Just a heads up but on the ten horse motors, the seals spring likes to hold the points cam up above the points, especially if the cam is a loose fit on the crank. So when installing the flywheel, the crankshaft must be turned so the high point on the cam is centered between the rubbing blocks on the points. Failure to do this will result in a bent points arm or something else if the flywheel is forced down as the cam will not clear the points arm and will get hung up.
