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.
