Info

Begin carburetor teardown by removing the external hardware; automatic-choke assembly, fuel fllter, throttle solenoid and any other items which have been hung on your carburetor. Don't overlook removing the air-cleaner hold-down stud before you remove the carburetor top. It threads into the main body. After your carburetor is torn down and cleaned, lay out the rebuild kit. Be careful. There are several small parts that are easy to lose, particularly the ball check/s. There are more parts than you need. This allows one kit to be used to rebuild more than one carburetor model. filter-not the butterfly-and the choke lav out the parts in an orderly fashion. vacuum can and throttle solenoid or dashpot if yours is one of the later emissioncontrolled models. Remove the bowl cover. Don't forget - to remove the air-cleaner hold-down bolt from the center. You now have access to the float, its needle and seat, the venturi booster assembly and main jets. Also remove the discharge-nozzle screw, accelerator-pump discharge-ball check, and nozzle-and-venturi-booster assembly. Be careful with these parts. They are easily damaged and lost. Strip the bowl cover and throttle body of their "exterior" components. The main, or throttle body will have a power/ economizer valve, idle screws and accelerator pump. A tip here: screw the idlemixture screws in until they bottom, while counting the number of turns. Make a note of it for reassembly. After removing them, the cleaning-process can start. Soak the parts in carburetor cleaner or lacquer thinner-long enough to remove or soften the carbon and varnish deposits so they can be rinsed or wiped off. A note of caution: Don't soak any rubber or plastic parts in solvent. This includes the float. Otherwise, there's a good chance they will be ruined. After the parts have soaked for a while and you've rinsed and dried them off, blow all the passages out with compressed air, if you have it available. Be very careful not to get any solvent in your eyes when doing this. Assembly-Relying on the instruction sheet that came with your rebuild kit, begin assembling your carburetor. First open up the kit too, but be careful not to lose any of the little parts-ball check, gasket, clips and the like. I leave the parts in the box, but fix it so I can easily see them. Put the exterior parts on the throttle body first, the economizer/power valve, idle jets and the accelerator pump and its linkage. Be careful during the assembly that you don't over-tighten any component. You are working with delicate parts and soft material. There aren't any torque specifications, so you'll just have to rely on your grey matter. Start with the inside. Install the main jets using a screwdriver that fits tightly in their slots. The next job is more than just assembly-setting float level or height. Float level governs the fuel level in the bowl, so it must be right. Check float level by installing the float, its needle and seat. Lightly hold the float and its needle in the closed position. Using the floatlevel gage that came in your rebuild kit, check the float position in the bowl. Position the gage across the top of the float Installing the booster-venturi assembly involves several parts. Ball-check and its weight go in first, followed by gasket, booster, booster-venturi screw and its airdistribution plate or gasket. bowl, and measure down to the top of the raised float, using the correct tab on the end from which the needle the q-he kit's sDecification sheet then reinstall it for a recheck.

Gage works for several carburetors, so refer to the specification sheet to find the float-height you are checking. Rather than pushing down on the needle-end of the float to check height like thls, hold carburetor upside down so float is hanging. Before installing the bowl cover, install the choke vacuum-break diaphragm assembly if your carburetor is so equipped. A flat nylon seal goes under the cover to seal the diaphragm linkage. Don't forget it. Install the bowl cover with its gasket, four bolts and the center air-cleaner bolt. When installing the idle-mixture screws, run them in until they bottom lightly, then back them off the same number of turns you noted during the teardown. Your carburetor may not be set exactly right for idling, but the idle-mixture adjustment should be close to the correct setting. To complete the assembly, install all the hang-on parts, the choke, throttle solenoid or dashpot, choke vacuum can and a new filter. Hooking up the linkages to all these parts and getting everything adjusted can turn out to be the most challenging job of rebuilding your carburetor. Follow the kit instruction sheet closely. TESTING AND CALIBRATION After your engine is installed with its new or rebuilt carburetor and distributor, you'll want to make sure they will perform at their peaks-maximum mileage and power with a minimum amount of pollutants. Distributor and carburetor tuning are major factors in determining an engine's performance, and to tune them to their full potential requires expensive and sophisticated tuning equip- .,. ment at the hands of a tuning specialist. This is the subject of the last chapter. Adjusting float height. Bend down tab from which needle hangs to lower the float. Bend it up to raise float. Install float and recheck its helght. Install choke-linkage dust shield and top gasket. There may be a couple of these gaskets in your kit. Find the correct one by matching it up with your old gasket. Dust shield prevents unfiltered air from being drawn Into the carburetor through the choke-linkage clearance hole. After carburetor top is in place, you can add all the external hardware. Don't forget to replace the identification tag. Finish up by installing throttle solenoid.
