FLOAT HEIGHT ADJUSTMENT

1. Illustration 1: Place the throttle side of the carburetor
on a level surface to remove weight from float arm. In
this position, the float tongue will rest slightly outward.
2. Illustration 2: With the carburetor still resting on the
level surface, use one hand to slightly tilt the
carburetor back. The float will then fall into the correct
position, with the float tongue resting lightly on the
inlet needle valve pin without compressing the spring.
The bottom of the float should be parallel with the float
bowl mating surface. Illustration 3: NOTE: If the float
is past parallel with the mating surface, the carburetor
has been tilted back too far and the float tongue is
likely compressing the needle valve pin.
