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