ADJUSTMENTS
- Remove air horn (bowl cover) and turn it upside-down
- Install air horn gasket on air horn
- Ensure that floats are resting on seated needle
- Measure from bottom side of float to gasket surface
- Refer to specifications for correct measurement for your particular carburetor
- If adjustment is needed, bend float lever
- NOTE: DO NOT allow lip of float lever to press against needle when adjusting. This will damage needle and cause carburetor flooding and incorrect float level
Watch a video about adjusting the float.
NOTE: aftermarket floats are shaped differently
TESTING
- The nitrophyl type of Thermoquad float is solid and can only be tested by weighing. Weight should be 7.5 - 8 grams.
- Brass floats are tested by heating a pan of water just prior to boiling. Immerse the float. Any bubbles will indicate a leak.
