SETTING CORRECT FLOAT HEIGHT

HONDA CB750 CB350 CB360 CT70 CARB FLOAT LEVEL GAUGE

Before changing any jetting parts, check the carburetor for the correct float height.  Measure the height from the bottom of the float to the carb body gasket surface (where the float bowl mates with with the float bowl removed). When the checking the height the float should be resting on the float needle pin (but NOT depressing it), this can accomplished by holding the carb body at an angle until the float tab rests agianst the float needle pin.  If adjustment is needed bend the metal on the float arm until the correct height is achieved.
