CARBURETOR
Float height measurement steps :
• Install the needle valve, float and float pin into the carburetor body.
• Hold the carburetor upside down.
• Measure the height distance between the mating surface of the float chamber (gasket removed) and the top of the float, using a gauge.
NOTE:
The float arm should be resting on the needle valve. It should not compress the needle valve.
• If the float height is not within specification, inspect the needle valve, float and valve seat.
• If one of these parts is worn, replace the whole set.
• If both parts are in good condition, replace the float.
• Check the float height again.
NOTE: The float height is factory-adjusted. Never try to adjust it yourself.
