I do not know how many without research, but it must be equal to sprocket on half time gear.

I am not with my Atlas. I am not with my reference books. I do not know how many teeth on magneto sprocket.

However, magneto or distributor sprocket and dual sprockets on half time (or intermediate) gear, and camshaft sprocket must be the same, or else magneto and cam will not be in time. Therefore, if you know teeth on cam or intermediate sprocket, you know distributor sprocket.

Capese?
