9-1-1 OPERATION AND CONSTRUCTION
1) FLOAT SYSTEM
The float chamber is located below the carburetor
body and, with a float and a needle valve,
main-
tains a constant fuel level during engine operation.
(See
Fig.9-2.)
The fuel flows from the fuel tank .into the float
chamber through 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 closes to shut
off the fuel, there by
keeping the fuel at the predetermined level.
