Float Level
With carburetor off engine, remove fuel bowl cover and invert carburetor main body so that weight of float only is holding needle valve against seat (hold fingers against fulcrum pin retainer to fully seat pin). Use the correct gauge or a scale (see specifications ) and measure distance between surface of fuel bowl and crown of each float at center. To adjust, bend lip of float lever.
CAUTION:
When bending float lip, do not allow lip to push against needle valve which is rubber tipped.
