I never saw any figures, they depended on the magneto stop. (I cannot find it in the parts book, but i have seen it on the motor.) Dad had a tool from engineering that screwed into a spark plug hole. With the piston at Top Dead Center it screwed it until it touched the plunger in the center of the tool. Then the flywheel was turned counter clockwise and the plunger was pushed in. the flywheel was then turned clockwise until a line on the plunger became visible. The stop was then held against the magneto plate and the bolts holding the stop tightened. 😕
