Float Level (Primary Fuel Valve)
Adjust nuts on float level checking gauge for correct float level setting (see Specifications ). With air horn and float assembly removed and inverted, install float gauge over floats with locating bolts installed in outboard holes of air horn. Both floats should just touch underside of float gauge bar. Align floats by slightly twisting float arms, adjust float height by bending primary needle tab (inner tab on float arm) up or down as necessary.
