Model "BC" Carburetor employs the conventional
float needle and seat to control the
fuel level in the float bowl. In accordance with
concentric float bowl design, dual floats are
used to maintain fuel level. (As shown in Figure

In this manner, the float
needle is drawn from its seat
by the float as the fuel level lowers, thereby
permitting an ample entry of fuel into
the bowl to meet increase engine demand.
feature also serves to retract the

might tend to cause a sticking condition.
