Fuel Level

Fuel level may be checked without removing carburetor top cover when using fuel measuring glass tool (P-77).

1. Connect measuring glass tool to fuel outlet at float housing. Pour fuel into float housing. Use a 2.3 meter (7.6 ft.) high fuel column to obtain correct pressure.
2. Close off fuel supply and read fuel level. The correct level should be 0.728" ± 0.04" (18.5 mm ± 1.0 mm) measured from edge of carburetor housing to fuel level surface.
