Wet Float Adjustment
With air horn and gasket installed temporarily on carburetor, idle engine for at least three minutes to stabilize fuel level in bowl, then remove air horn and gasket. With engine idling, use "T" scale to measure from top machined surface of bowl to surface of fuel at a point at least 1/4" away from any vertical surface. If fuel level not correct, stop engine and adjust by bending float tab toward or away from inlet needle as required.
CAUTION:
Do not allow float tab to contact needle while making adjustment.
Repeat entire procedure to recheck fuel level. After adjustment completed, install air horn and gasket and make necessary carburetor adjustments.
