Float adjustment: With throttle body inverted and gasket removed, there should be (the clearance indicated above) between machined surface of throttle body and seam of float. Measure both sides and make them the same.
Idle Adjustment: Set throttle lever adjusting screw until motor runs approximately 400 RPM. Then set idle adjustment screw for highest steady vacuum gauge reading or smoothest engine operation. Correct setting will be found between 1/4 to 1 1/2 turns open.
High Speed Adjustment: With hand throttle wide open and engine operating 2000 RPM (governed speed), adjust high speed adjusting needle until smoothest engine operation is obtained. This setting will be found between 3/4 to 1 1/2 turns open.
