10 5 50 Fuel system 3 Check that the carburettor is tight. No leakage is permissible at 50 kPa pressure. Connect pressure tester No. 501 56 27-01 to the fuel inlet in the carburettor. Pump up to 50 kPa pressure. Submerge the carburettor in a jar with petrol to simplify inspection for leakage. No leakage is permissible. 30 200 150 250 15 100 300 350 50 400 0 20 0 25 35 40 60 45 55 501 56 27-01 Fit the metering diaphragm and compensation insert for air filter blocking. Place the gasket on the carburettor housing and then the metering diaphragm. NOTE! Make sure that the pin on the diaphragm goes into the groove on the lever. Fit the blue compensation insert and then the cover. Tillotson HS E D A B C Mod. 950 The carburettor is of Tillotson (HS 282A) manufacture, and has in principle the same design as the carburettor for mod. 650, 700. The speed limiter, however, has been replaced by an electronic limit via the ignition system. The adjustable jets have been re-placed by fixed jets. A = Main jet (high speed) B = Low speed jet (behind washer plug) C = Idle screw D = Main nozzle E = Part throttle jet F = Fuel screen F The service method for this carburettor is the same as for mod. 650, 700. The main jet (A) can be dismantled for cleaning or replacement. To gain access to the low speed jet (B) the welch plug must be removed. 31
3 Fuel system Walbro WG 9 A C B Mod. 1250 The carburettor on this model is of Walbro manufacture. The service method is the same as for the Tillotson carburettor. Note the small O- ring (A) placed on the compensation device. This carburettor does not have a speed limiter either. A = O-ring B = Main nozzle C = Main jet (high speed) D = Low speed needle E = Adjuster screw for idle speed F = Fuel screen The main jet (C) can be dismantled for cleaning or replacement. E D F T H L Fit the carburettor on the engine in the reverse order to dismantling. Use new gaskets Check that the gaskets are turned the right way round so that the impulse channel is not blocked. Carburettor setting (not EPA models) ! WARNING! When test running the engine in connection with the adjustment of the carburettor the clutch, cutting arm and cutting disc must always be fitted. Otherwise there is a risk that the clutch may release and cause serious personal injury. Function The purpose of the carburettor is to supply a combustible mixture of air and fuel to the cylinder. The volume of this mixture is regulated with the throttle control. The composition of the mixture of air and fuel is regulated with the adjustable nozzles ”H” and ”L”. The carburettor should be adjusted if: ● The cutting disc rotates when the engine is idling. ● The engine speed does not go down to idle from full throttle within 3-5 seconds. ● The engine does not run on idle. ● The engine does not respond quickly to the throttle. ● The engine seems to lack power. 32 NOTE! EPA models have carburettors with fixed jets "H" and "L". This means that they can not be adjusted
