Float Height Adjustment - Polaris Sportsman 400 Service Manual

FLOAT HEIGHT ADJUSTMENT

1. Place the carburetor on a level surface as shown at
right to remove weight from float arm. In this position,
the float tongue will rest lightly on the inlet needle valve
pin without compressing the spring.
2. Measure the height from the float bowl mating surface
to the top of step in float as shown. Both sides of float
should be parallel to each other. The measurement
should be made at the mid-point on the top of the float
using float adjustment tool (PN 2872314) or a vernier
caliper. When measuring the height be sure the inlet
needle valve spring is not compressed.
Float Height:
13.0mm (.51") ± 1 mm
Std: BST 34
14.7mm (.58") ± 1 mm
BST 40
3. If adjustment is necessary, bend the tongue slightly.
Be sure float arms are even on left and right side.
