Float Level
Invert air horn and float cover assembly, allowing float to hang free Distance from top of float to gasket surface on cover (gasket removed) should be as indicated in specifications To adjust, bend lip that contacts intake needle valve (see Figure).
CAUTION:
When gauging float level, only the float weight should rest on intake needle (excessive pressure will compress resilient seat or spring-loaded needle and cause false setting).
Do not allow float lip to contact needle when making an adjustment.
