The spark plug gap is .027, the points gap is .015.
When installing flywheel, don’t force it in case the flywheel points cam is hitting the points if the points are way off.
The fuel mix is 2/3 pint of SAE 30 wt oil per gallon of gas for normal use. Can be reduced to 1/2 pint oil for extended trolling.
The prop nut should have left-hand threads and no cotter pin.
The water pump has 2 check valves which should be clean, not oily. Clean intake screen.
Carb setting is 1 1/4 turn open for high speed needle, 1/2 turn open for low speed needle (screwdriver slotted).
Magneto: Piston position is irrelevant for point setting. When the points are viewed through the triangular window, gap is .015. When the points are viewed through the round window hole they should be seen opening and closing with slight flywheel movement. Test the points gap, adjust, repeat until .015″.
Starting cold: Set both carb needles.
Set carb throttle lever at halfway point.
Lift up choke lever to choke.
Start.
Adjust needles to best running position.
