CLOTHINGTo hundreds of thousands of enthusiasts,snowmobiling has added an entirely newdimension to WINTER. However, to trulyenjoy the fun, there is one item that is asindispensable as your snowmobilewarm,safety clothing.Safety ClothingHelmet (C.8A and A.S.A. (Z.90.1) approved).Snowmobile suit: Reinforced at stressareas - wind and water resistant.Boots: Lightweight and waterproof.Mitts: Strong - Padded - Windproof.Goggles or Visor: Interchangeable lenses.Tuque.Chill FactorAs the Chart shows, even moderate temperatures,when coupled with vehiclespeed or wind velocity, produce a chillfactor often as much as 20 to 30 degreesbelow thermometer readings.Bombardier Limited, the people whoknow snowmobiling best have consideredyour comfort and safety with a completeline of cold weather clothing. Fromunderwear to outerwear in high-fashionstyling, these garments and accessorieshave been laboratory and field tested tokeep you warm and give you the comfortand freedom of movement that the sportdemands.Marketed by Ski-Doo Sports Limited (asubsidiary of Bombardier Limited) andstocked exclusively by authorized Ski­Doo dealers displaying the Ski-DooSports Logo, you are guaranteed warmer,safer winters when you wear certifiedSki-Doo sportswear.WARNING: Under no circumstancesshould you wear loose clothing orscarves that could become entangledwith moving parts of your snowmobile.Wind velocity or snowmobile speed5 10 15 20 25 30 35 4035 32 22 15 11 7 5 3 230 27 16 9 4 0 - 2 - 4 - 625 21 10 2 - 3 - 7 -10 -12 - 1420 16 4 - 5 -10 -15 -18 -20 - 2115 11 - 2 -11 -17 -2210 6 - 9 -185 0 -150 - 5 -21-5 -10-10 -15-15 -20-20-25-30Increasing danger from freezing of exposed flesh• Great danger from freezing of exposed flesh5

DRIVING HINTSDriver confidence and capability are thekeys to full enjoyment of your new Ski­Doo snowmobile. For your first few runs,select a large, clear, flat area then practicethe uses and responses of the variouscontrols and get the feel and balanceof your vehicle.When first using throttle and brake, mostbeginners press and release the leverstoo quickly, causing a corresponding"jerking" of the machine. Instead,squeeze the levers firmly and smoothlyso acceleration and braking are even.When braking, remember that snowmobileshave a broad, flat track in continuouscontact with the ground, so thatthe vehicle immediately starts to slow ofits own accord as soon as the throttlelever is released. For most circumstances,this natural slowing action plusa gentle pressure on the brake are morethan sufficient to stop the vehicle.Driving PositionsThere are 3 main driving positions on asnowmobile - (1) Standing, (2) Kneeling,and (3) Sitting.Each presents certain advantages dependingon the nature of the terrain, thesnow conditions, speed of the vehicle,the turns you desire or the personal preferenceof the driver.(1) Standing - a position often adoptedby beginners, allows for better weight6distribution and permits you to respondto the movement of your snowmobilewith surer control. With this position,however, always keep your knees slightlyflexed to absorb surface shocks.The position is undoubtedly the best forsteep hills, climbing or going down, ashort stretch of very bumpy trail or whenmanoeuvering in deep snow.(2) Kneeling - crossing a steep slope,for example, from side to side, you willfind the kneeling position a definite advantage.Place one foot on the footboard(on the high side of the hill), the oppositeknee on the seat, then lean into the hill.If leaning left, your left foot should be onthe footboard, your right knee on theseat, and vice-versa.WARNING: Side hills and steep slopesare not recommended for a beginner.An alternate recommended kneeling positionand one that is frequently used, isto place both knees on the seat, with onefoot on each side, loosely pressingagainst the seat. This posltlon is usefulshould you encounter bumpy trails wheresitting is uncomfortable.(3) Sitting for all normal driving, themost comfortable position is the sittingposition. Toes should be held loosely inthe stirrups, body about midway back onthe seat and body weight distributedevenly between the seat and footboards.Quick TipsWhen necessary to turn your snowmobilearound by hand, always lift back endrather than front.If you have to turn your vehicle around byhand in deep or loosely packed snow,first press down firmly on the tips of yourskis. This will raise the trailing edges, sothat they do not dig in while vehicle isbeing turned.TurningIn turning, you will quickly find that oftenyou cannot rely on the handlebars aloneto turn within the circle you desire. Part

of the fun of snowmobi ling is that eachturn depends on 4 factors the radiusof the turn, vehicle speed, snow conditionsand the weight on the skis.To make those tight, fast turns that arethe mark of the experienced driver, youmust learn to use the weight or positionof your body, shifting to left or right asthe turn demands and keeping your centreof gravity as low as possible.In soft or lightly packed snow, the theoryof weight shifting is that by leaning thebody toward the inner side of the turnyou increase the pressure on that edgeof the track and correspondingly lightenthe other edge. In effect, you create abank of snow under the lighter edge, sothat the vehicle is banked when turning.On hard packed snow, leaning in towardthe turn and at the same time keepingyour centre of gravity as low as possible,counterbalances the natural tendency ofany vehicle to tilt when turning.Also, moving your body weight towardthe front of the vehicle, particularly, inhard-packed snow, adds pressure to theskis and ski runners so that they bitemore deeply into the snow surface.IMPORTANT: Thoroughly know yourvehicle and how to drive it before attemptingdifficult or rapid manoeuvres.Surface ConditionsDeep Snow - Your new Ski-Doo snowmobileis designed to negotiate almostany snow surface, including deep ornewly-fallen snow. Two things are importanthowever, - (1) don't overloadyour machine (i.e. travel alone, not withpassengers) and (2) maintain a reasonableforward speed at all times. Don'taccelerate beyond the track's ability tocope with the surface underneath, anddon't stop.Use the standing position recommendedearlier and if your vehicle continues tomake reasonable headway, respondingto light changes in acceleration, you aresafe enough to explore new areas.Icy Surface - Ice or extremely hardpackedsnow can be difficult to negotiateas both skis and track do not have muchtraction. Best advice is to slow down andavoid rapid acceleration or braking.TipsFor vehicles equipped with a slider suspension:During normal driving, snowwHI act as a lubricant and coolant for theslider shoes. Extensive riding on ice orsanded snow, (not to mention dirt, asphalt,etc. never recommended) maycreate excessive heat build up and causepremature slider shoe wear.7

DO'S• Register your Ski-Doo snowmobile atyour nearest Licensing Bureau, whereState or Provincial Laws require it, andaffix Registration Plate to the vehicle.Carry your registration certificate withyou. It provides proof of ownership in theevent that the vehicle becomes lost orstolen.• Obtain your State or Provincial bookleton snowmobiling. It gives valuable informationon the neighbouring snowmobiletrails and the laws governingsnowmobiling in your particular area.• Always carry emergency materials andsupplies. Your local Ski-Doo dealer hasa Safety Centre prepared specially foryou.• Let every riding member of your familyread the entire Owner's Manual. Theknowledge and confidence gained willreduce the risk element.• Observe all posted snowmobile signs.Not all private landowners allow snowmobilingon their property. You can havejust as much fun, even more so, by travelingelsewhere.• Before you start out, check to be surethat you and each member of your partyare equipped with sufficient warm clothingand safety helmets.• When snowmobiling with others, limityour actions to the experience of themain body. Show the inexperience driverhow to properly handle at snowmobile.8• Use the 'buddy" system. Always travelwith at least one other snowmobile, especiallyin unfamiliar terrain or on trailrides. Even in snowmobiling, a pair beatsone of a kind.• If you are planning to explore newareas, leave word of your approximatewhereabouts and estimated time of returnwith someone. Remember, a snowmobilecan often travel farther in 15 minutesthan you can walk in a day.• Always make a full stop, then lookcarefully in both directions before crossingroads. When traveling in pairs or ina group, have one member direct theothers across, singly.• Use a rigid hitch or tow-bar when pullingany sled or trailer behind your Ski­Doo snowmobile. Rigid hitches preventtailgate collision when gGing downhill oron sudden stops.• Be extremely careful when givingchildren a ride. Go more slowly andcheck frequently. Small children, are farsafer in a Ski-Boose" sled than on theseat of your snowmobile.• When trailering your Ski-Doo snowmobile,secure it solidly at both ends,protect it with a bright cover (Ski-Doo*cover) then check that trailer hitch andsafety chain are secure and that brake,flashers and parking lights are all inworking order."Trademark of Bombardier Limited

DONT'S• Don't cut across in front of the line oftravel of another snowmobile. Don't tailgate;collision, or the threat of it, is seriouswith any moving vehicle.• Don't risk injury or damage to yourmachine with needless and foolish stunting.Don't "jump" your snowmobile. Thispart of snowmobiling should be left tothe professional "stunt" men.• NEVER ride on railway tracks. Thesounds of your moving vehicle drown outnoise of approaching trains. Your vehiclemay also become caught in track junctions.In many States and Provincessnowmobiling on railway tracks constitutesan infraction of the law.• Never cut through fences or attemptto run over them. Give a wide berth totelephone poles. Hidden guy wires, unseenfrom a distance, can cause seriousaccidents.• Don't lend your snowmobile to inexperiencedor under-age drivers. In manycases it is the vehicle owner and not therider that is responsible for mishaps.Check State or Provincial minimum agelimits for drivers.• Unless you are certain of a fuelingstop, never travel further than 1/2 of thefuel remaining in your tank. Even then,leave yourself a safety margin. Rememberthat a snowmobile does not necessarilytravel the same distance each timeon the same amount of fuel. A lot dependson speed, the snow conditions ofthe trail and the adjustment of the carburetor.• Don't drive your snowmobile in thevicinity of skiers and keep off ski trails.Always respect the rights of those whoenjoy winter in another way.• NEVER ride on earth, grass, asphalt orlike bare surfaces.• "If you drink don't snowmobile! If yousnowmobile, don't drink!" RememberAlcohol and gasoline don't mix.• Don't overload your snowmobile. ASki-Boose sled or other trailer carries farmore than your snowmobile can, withoutnoticeable loss of efficiency or manoeuverability.• Don't cross a river or lake without firstbeing positive that the thickness of theice is sufficient to support both you andyour vehicle. Your life may depend on it.If at all in doubt, take an alternate route.• Don't ride on public streets, roads orhighways. The single largest cause ofaccidents have occured when snowmobilesand automobiles mix.• Don't leave your keys in the ignitionswitch. It prevents an invitation to thievesand a danger to children.9

FUEL MIXINGRegularoil20/1orWith Ski-Doo snowmobiles, the OIL mustbe added to the GASOLINE in pre-measuredamounts then both oil and gasolineshould be thoroughly mixed together,BEFORE fueling the tank.The importance of using the correct fuelmixture cannot be over-stressed. Priorexperience has shown that the largestcause of engine damage is from incorrectfuel mixtures.12Which Gasoline to UseThe correct gasoline for your Ski-Doosnowmobile is regular gasoline, (notless than 88 octane) available from allservice stations.CAUTION: Never experiment with differingfuels or fuel ratios. Never use premiumgasoline, naphta, methanol or similarproducts.Which Oil to UseUse only Ski-Doo* oil available in regularor concentrated form. Both typeshave especially formulated oil bases tomeet the lubrication requirements of theBombardier-Rotax engine.CAUTION: Unless absolutely necessary(in case of emergency) do not use outboardor straight mineral oil. Never usemulti-viscosity oils.Fuel Mixing RatioWhen using REGULAR SKI-DOO OIL,the correct mixture is 20/1.5 GALLONS, REGULAR GASOLINE plus1 QUART, REGULAR SKI-DOO OIL =CORRECT FUEL MIXTURE.When using CONCENTRATED SKI-DOOOIL, the correct mixture is 40/1.5 U.S. GALLONS or 4 IMPERIAL GAL-LONS plus 1 PINT CONCENTRATEDSKI-DOO OIL CORRECT FUEL MIX­TURE.Note: To facilitate fuel mixing, concentratedSki-Daa oil should be kept at roomtemperature.Fuel Consumption TableThrottle R.P.M.

Resultshave been obtained by running statictests under full load, but cannot take intoaccount such factors as snow conditions,carburetor adjustments, etc.Fuel Mixing ProcedureTo mix the gasoline and oil always use aseparate clean container. Never mixdirectly in your snowmobile tank.Note: For best results, acquire two containers,either plastic or metal. Draw fromone until empty then use the second one.Meanwhile, refill the first as soon as convenient.WARNING: Gasoline is flammable andexplosive under certain conditions.Store in a well ventilated area. Alwaysstop the engine and do not smoke orallow open flames or sparks near thevehicle when refueling. If gasolinefumes are noticed while driving, thecause should be determined and correctedwithout delay.1. Pour the full amount of Ski-Doo oilrequired for the total mixture into thecontainer.2. Add approximately half the amount ofgasoline to be mixed.3. Shake the container thoroughly.4. Add the remainder of the gasoline.5. Once again thoroughly agitate thecontainer.6. Using a funnel with a fine mesh screento prevent the entry of water and foreignparticles, transfer the mixture from thecontainer into the snowmobile tank.13

PRE-START CHECKFuel Tank QuantityCheck that there is sufficient fuel in thetank for your trip. A good habit to acquireis to refill the tank before starting outeach day.Since mixed fuel has a tendency to settleovernight, agitate the fuel in the tank bystanding on the footboards and rockingthe vehicle from side to side.Track (Daily, before first run)Under certain climatic conditions, thetrack of a snowmobile left outdoors overnightmay freeze to the ground or snowsurface. Always make sure that the trackis free before attempting to start the vehicle.(This procedure will eliminate unnecessarydrive belt wear).Steering OperationCheck operation of steering mechanismby rotating the handlebars several timesfrom side to side. If roughness or bindingis felt, check for ice or snow that may beblocking the mechanism.Throttle and BrakeDepress and release levers several timesto check that they operate easily andsmoothly. The throttle lever should returnto the idle position when released. Thebrake lever should be fully applied whenit is 1" (minimum clearance) from thehandlebar grip. If the levers do not return14swiftly, remove cables and/or housingsand replace. Re-check lever operation.Do not start the engine until levers returnswiftly.WARNING: Always check throttle andbrake operation before starting engine.YOU MAY NOW START YOUR SKI·DOO SNOWMOBILE.BREAK-IN PERIODWith Ski·Doo snowmobile engines,a break-in period is required beforerunning the vehicle at full throttle.Manufacturer's recommendation forthe Bombardier-Rotax engine is ten(10) operating hours or the equivalentfuel consumption, (See page 12 for theequivalent fuel consumption of yourvehicle). During this period, maximumthrottle should not exceed 3/4, exceptmomentarily to attain cruising speedor avoid emergency. Before you tookdelivery of your new Ski-Doo snowmobile,the carburetor was adjustedby your Dealer for a rich fuel mixture.This permits better lubrication andcooling of the engine. Do not readjust,regardless of excessive smoke in theexhaust.InspectionAs with any precision piece of mechanicalequipment, we suggest thatafter the first 10 hours of operation or30 days after purchase whichevercomes first, that each Ski-Doo snowmobilehas an inspection check. Thisinspection, which should take approximately1¥2 hrs., is at the discretionand expense of the vehicle owner.

4. Check spark plug gap using a wirefeeler gauge. Gap must be .020", adjustand/or replace if necessary. Reinstallplug.(W2) Battery (Electric Model only)Remove battery caps then check electrolytelevel at each cell. Electrolyte levelmust touch bottom of filler hole. If necessary,add Distilled Water up to this level.(W3) Suspension SpringsWith engine OFF, visually inspect suspensionsprings. Replace any weak orbroken spring.(W4) TrackLift the rear of the vehicle and support itoff the ground so that the track is free toturn. With engine turned OFF, rotate trackby hand and visually inspect track condition.If bad cuts or missing inserts (SeeGlossary, page 30) are noted, see yourdealer.Note: Without these inserts continualabrasion would wear and cut the tracktherefore, always teptece a missing ordamaged insert as soon as possible.(W5) Track Tension(bogie wheels)With rear of vehicle off the ground, checkthe track tension from the middle set ofbogie wheels. The track tension (distancebetween top inside edge of trackand bottom of footboard) should be 21Ainch plus or minus Va inch (See Fig. 11).20Fig. 11 ~"""""'''''IIIIIiIIIii''''''IIIIliiiIl'''I''''''''''''''''''(slider suspension)Lift rear of vehicle and support it off theground. Allow pressure of slider to extendtrack normally. The tension (distancebetween footboard and inside oftrack) should be 5 3 A. to 6 inches. (SeeFig. 12).If track tension is too loose, the track willhave a tendency to thump. If too tight,performance will be affected.If necessary to adjust:1. Using wrench, loosen both track adjustersby unscrewing the lock nuts situatedon the inner side of the suspensionsprings (See Fig. 13).and 14).2. Adjust to proper tension by turningadjuster bolts, clockwise to tighten trackcounter-clockwise to slacken. Adjustboth sides equally (See Fig. 14).3. Proceed to track alignment.Note: Track tension and alignment areinter-related. DO NOT adjust one' withoutchecking the other.(W6) Track AlignmentAfter track tension has been corrected,start the engine and accelerate slightlyso that track turns slowly. Check thattrack is well centered and turns evenlyon the rear sprockets.The distance between the edges of thetrack and the link plates should be thesame on both sides. (See Fig. 14). Misalignmentcan cause excessive wear oftrack edges and sprocket teeth.

To adjust:1. Turn track adjuster bolt clockwise onthe side where the track is closest to thelink plate until track aligns.2. Firmly retighten adjuster lock nuts.3. Rotate track slowly and recheck alignment.(W7) Carburetor AdjustmentThere are four different adjustments forthe carburetor.(1) Maximum Throttle Opening, (2) IdleSpeed Mixture, (3) Idle Speed, and (4)High Speed Mixture.Maximum Throttle OpeningWith engine OFF,unscrew the Idle SpeedAdjusting screw until a gap exists betweenscrew end and carburetor shaftlever. Depress the throttle lever athandlebar and hold. Throttle butterflyshould be horizontal when the lever gentlytouches the handlebar grip.To adjust for maximum opening, loosenscrew at point where cable joins carburetorlever.With finger, hold carburetor throttle leverin fully open position (UP), pull cabledownward until taut. Retighten screw,ensuring throttle is fully depressed.WARNING: Before starting engine,make sure carburetor throttle leverreturns to idle position when handlebarthrottle lever is released.Idle Mixture AdjustmentA primary adjustment (with engine OFF)should be made by first turning idle mixturescrew fully clockwise until closed.Back off screw 3/4 of a turn counterclockwise.(See Fig. 15).Turning screw clockwise produces aleaner mixture; (more air/less fuel);counter-clockwise, a richer mixture (lessair/more fuel).Note: Do not close too tightly as needleand/or needle seat can be damaged.For final adjustment, start engine andallow it to warm up. Turn idle mixturescrew until engine reaches maximumR.P.M. and obtain a steady idle and a fastresponse of the engine to the throttle.Idle Speed AdjustmentTurn the idle speed adjusting screwclockwise to increase idling speed, counter-clockwiseto decrease. (See Fig. 15).High Speed Mixture AdjustmentWARNING: High Speed Mixture adjustmentmust be carried out only by anauthorized Ski-Doo dealer.For primary adjustment however, withengine OFF, turn high speed mixture adjustingscrew fully clockwise until itcloses. (Do not close too tightly as screwand/or screw seat can be damaged).Then back off screw 1V4 turns counterclockwise.(See Fig. 15).(W8) Drive Belt ConditionTo check the condition of the drive belt:1. With cab tilted, remove the consoleand pulley guard.2. Remove drive belt as detailed in LubricationSection. Page 17.3. Check condition of belt. Inspect forcracks, fraying or abnormal wear. (Unevenwear, wear on one side, etc.). If abnormalwear is noted, probable cause ispulley misalignment. (See your dealer).(M1) Battery ConnectionsCheck that battery connections are tightand free of corrosion. If not, remove corrosion,using a stiff brush then clean witha solution of baking soda and water.Rinse and dry well. After reconnecting,coat battery terminals and connectorswith petroleum jelly to retard corrosion.Check that battery is well secured.CAUTION: Do not allow cleaning solutionto enter battery. It wi/! destroy thechemical properties of the electrolyte.21

(M2) Carburetor flange NutsAfter the first two (2) hours of operation,check tightness of carburetor flange nuts.Tighten, if necessary. (See Fig. 16).If a minor adjustment is indicated: Slackenoff nut (A) and tighten nut (8) toincrease lever clearance. Turn each nutvice versa to decrease (See Fig. 17).To proceed with major adjustment:Slacken off the nut retaining brake cableto lower brake lever. Adjust cable to requiredlength and retighten nut. (SeeFig. 17). Ensure that minor adjustmentnuts are located approximately half wayon adjuster threads.3. Tighten the nuts firmly against the tierod. Firmly tighten the steering arm bolts.Note: In cese of serious misalignment,contact your dealer.~::=:;::~~~(M3) Muffler AttachmentWith cab tilted, tighten the nuts and boltsattaching muffler flange and brackets toengine. Loose muffler attaching partswill greatly reduce muffler life.(M4) Drive Belt WearTilt cab, remove console and pulleyguard. Inspect drive belt for wear. If beltis less than 'l's" wide, it should be replaced.(MS) BrakeThe brake mechanism on your snowmobileis an essential safety device. Keepthis mechanism in proper working condition.Above all, do not operate yoursnowmobile without an effective brakesystem.Check operation of brake mechanism bydepressing brake lever. Brake shouldapply fully while lever is still 1 inch minimumfrom handlebar grip.22(MS) Steering AdjustmentsSkis should be parallel to each other. Tocheck, use metal tape and measure distancebetween skis at front and back.The skis should also be parallel to vehiclewhen handlebar is horizontal. If adjustmentis required:1. Unscrew the nuts locking the tie rodsin place.2. Turn one or both tie rods until skialignment is correct (See Fig. 18)~(M7) Engine Head NutsWith cab tilted, check that engine headnuts are tight and equally torqued, (16 to18 ft./lbs when COLD).(MS) Engine Mount NutsWith cab tilted, remove console andpulley guard then check engine mountnuts. Retighten if necessary.(M9) Vehicle General InspectionWith cab tilted, check electrical wiringand components, retighten loose connections.Check for stripped wires ordamaged insulations.

EMERGENCY GUIDEThe following charts list the "most likely to occur" problems, their possible causesand remedies. Should you encounter trouble on the trail, first identify the symptomsthen rectify, using your manual to assist you.What To DoIf headlamp is burnt, stop engine, unlock cab latches (2) and tilt cab. Unfasten bulbretainer clips. Detach bulb and replace. If taillight bulb is burnt, expose bulb byremoving red plastic lens. To remove, pry off red plastic lens using flat bladedscrewd river.Remove throttle cable and replace. Check lever operation. If necessary replacehousing. Do not start the engine until levers return swiftly. (See Throttle andBrake, page 14).If rope is broken inside starter unit, remove starter unit, using 10mm wrench suppliedin Tool Kit. Make a knot at end of remaining rope at end opposite handle.Wind remainder of rope around pulley. Pull vigorously, as per usual manual start.(See page 23).If rope is broken at handle, remove starter unit. Fish rope out, being careful toretain all loose parts of unit. Wind remainder around pulley. Start in usual manner.See your dealer for immediate repair or replacement.In case of major damage, remove ski coupler bolt, using wrench. Remove skiand return on remaining ski. Shift body weight to keep vehicle in balance.If both headlamp and taillight go out at same time, most possible cause is burntfuse. Check light fuse filament, if broken, replace. Light fuse is in fuse holder onred wire going from ignition to light switch.In emergency, fuel can be siphoned from companion or passing vehicle. Tosiphon, disconnect both fuel lines of vehicle with fuel, at carburetor. Positionvehicle with fuel higher than vehicle with empty fuel tank. Run longer line intoempty fuel tank, (or container, if available). Placing hand over open filler neck oftank with fuel, to form a seal and build pressure, blow into open end of shorterfuel line until flow starts.24

TROUBLE SHOOTING GUIDEWhat To DoCheck the tank level and fill up with correct gas-oil mixture. (Refer to Fuel Mixing,Page 12). Check for possible clogging of fuel line, item 5.Check for fouled or defective spark plug. Disconnect spark plug wire, unscrew plugand remove from cylinder head. Reconnect wire and ground exposed plug to enginehead, being careful to hold away from spark plug hole. Follow engine starting procedureand check for spark. If no sparks appear, replace spark plug. If troublepersists, check item 3.Disconnect spark plug wire from plug, unscrew the spark plug cap then holdwire about 1Js II from the cylinder head. Follow engine starting procedure and ifno sparks appear, it means a faulty ignition system. Do not attempt to repair.Contact your dealer.Turn choke knob to OFF, wait 60 seconds or more then depress throttle leverfully and try to start engine. Release throttle lever immediately after engine starts.Remove and clean the fuel filter. Change filter cartridge if necessary. Check thecleanliness of the fuel tank. Clean tank if necessary. (See Fuel Tank, Page 28).Screw in the idle speed mixture adjusting screw and turn it back % of a turn.Make final adjustment with engine running and warmed up.First make primary adjustments on carburetor. (See Maintenance Section). If carburetoris still faulty, contact your dealer for repair.Drain the fuel tank and refill with the correct gas/oil mixture. (Refer to FuelMixing).Breaker points may be worn or out of adjustment. Contact your dealer.Running with a lean fuel mixture may produce excessive engine wear resultingin poor engine compression. If this occurs, contact your dealer at once.In the case of a seized engine, contact your dealer. Seizure is a direct result ofpoor lubrication.25

What To DoCheck for loose or corroded battery and starter connections. Tighten and cleanif necessary. Try to restart engine electrically. If engine still does not start, checkitem 2.Check condition of battery by turning lights ON. If lights are dim or out, batterymay be discharged or defective. Contact your dealer to charge or replace.If wire connections are tight and fuse and battery are all in working order, mostprobable cause of trouble is defective starter. Contact your dealer for repair.Change your spark plug. Fouled spark plug may be cleaned, regapped and testedby your dealer. (See Spark Plug page 19).Remove and clean fuel filter. Change filter cartridge if necessary. Check fuel linecondition and connections. Check cleanliness of fuel tank. Clean if necessary.Readjust the carburetor. If the trouble persists, contact your dealer.First check items 2 and 3 of "Engine turns over but fails to start or starts withdifficulty". If the ignition system still seems defective, contact your dealer.If unable to locate specific symptoms, contact your dealer.Check item 1 of "Engine lacks acceleration or power"Carburetor set to lean. Readjust.Contact your dealer.Check for defective or worn drive belt. Replace if necessary.If the drive and driven pulleys are not aligned correctly, contact your dealer.Check track tension and alignment. Readjust to specifications. (See MaintenanceSection).Check items 1 to 5 of "Engine lacks acceleration or power".26
