      I cannot figure out how the points are supposed to open when the cam has a flat face a tdc rather that a bulge?  I’m really missing something here…20251228_104008

          Just move the point to widest opening on cam. the motor does not need to be on top dead center.

            The cam is the same width all around except for the “flat” section shown in the photo…
