SECTION 14 - FUEL SYSTEM
GENERAL INFORMATION
The engine is equipped with a float bowl type carburetor with fixed jets that require no adjustment. The car-
buretor atomizes the fuel, mixes it with air, and feeds the combustible mixture into the cylinder.
HOW THE CARBURETOR WORKS
MAIN SYSTEM
The main system of the carburetor consists of the main jet, the main nozzle, and the main air passage. The
main system meters fuel to the engine during moderate to heavy load conditions. Fuel flows through the
main jet and into the main nozzle, where it is meets air from the main air passage. The resulting mixture flows
out the end of the main nozzle and into the carburetor bore, where it is atomized by the high speed air flow
and then carried into the engine (Figure 14-1, Page 14-2 and Figure 14-3, Page 14-3).
During the intake stroke of the engine, a negative pressure (vacuum) is created in the venturi of the carbure-
tor. In this venturi tube, the intake air has high velocity and low static pressure. Subsequently, fuel is drawn
out of the carburetor float chamber, atomized to fine particles, and then drawn into the cylinder as a combus-
tible mixture (Figure 14-2, Page 14-2).
