Float Level

1. With engine running, check fuel level in bowl sight glass. If fuel level is not within specified range, remove carburetor from engine. Remove fuel bowl cover and invert carburetor.
2. Allow float to lower by its own weight. Measure clearance between float and edge of bowl. If clearance is not to specifications, bend float tang to achieve proper clearance. See Fig 1.
