CARBURETOR
Measurement and adjustment steps:
● Hold the carburetor in an upside down
position.
NOTE:
● Slowly tilt the carburetor in the opposite
direction, then take the measurement
when the needle valve aligns with the float
arm.
● If the carburetor is level, the weight of the
float will push in the needle valve, result-
ing in an incorrect measurement.
● Measure the distance between the mating
surface of the float chamber and top of the
float using a vernier calipers.
NOTE:
The float arm should be resting on the nee-
dle valve, but not compressing the needle
valve.
● If the float height is not within specifica-
tion, inspect the valve seat and needle
valve.
● If either is worn, replace them both.
● If both are fine, adjust the float height by
bending the float tab b on the float.
● Recheck the float height.
