If, with a cold engine, the throttle is operated several times,the pump injects into the mixing
chamber amply sufficient petrol for starting.
The cylinder of the accelerator pump is the lower enlarged extremity of the pump needle jet, into
which the pump piston with valve disc and the pump valve screw are inserted.
The pump spring presses the piston against the bottom end of the jet needle. The piston then moves
with this needle and when it goes up, fuel is conveyed to the mixing chamber.
The air necessary for combustion enters the carburettor through the air–filter and is passed under
the slide, the fuel emerging from the pump needle jet is added and the mixture is passed on to the
engine. The performance of the engine is determined by the slide opening.
As indicated in Fig.1, the fuel passes to the float chamber of the carburettor through the petrol
pipe connector (33), the petrol filter and the pipe connector locating nut (36). The float (27) and
the float needle (28) provide a constant fuel level in the carburettor. From the float chamber, the
petrol then flows into the pump jet cover (23) and to the idling jet (17).
