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 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 close
to
the shut off the fuel, thereby keeping the fuel at the reference level.
