metered through the pilot air jet. The intake air draws fuel, metered by the pilot jet (Figure 14-3, Page 14-3),
from the carburetor float chamber. The combustible mixture of air and fuel is then delivered into the venturi
through the pilot outlet and bypass. When the engine is operating at low speed, fuel is supplied mainly
through the pilot outlet (Figure 14-3, Page 14-3).
The air/fuel mixture is adjusted by the pilot screw (needle valve) (Figure 14-3, Page 14-3).
