8. CARBURETOR
8-1 OPERATION and CONSTRUCTION (See Fig. 37 and 38.)
8- 1 - 1 FLOAT SYSTEM
The float chamber is located just below the carburetor body and, with a float and a needle valve, maintains a
constant fuel level
during engine operation.
The fuel flows from the fuel tank into the float chamber through needle valve. When the fuel rises to a speci-
fic level, the float rises; and when its buoyancy and fuel pressure are balanced, the needle valve closes to shut
off the fuel, thereby keeping the fuel at the predetermined level.
