I am in a conference in Chicago right now and won’t be home to Green Bay until later tomorrow. I will try to post some pictures then to clarify. Until then:
– the flywheel is definitely hitting the mag plate – not the coils. It is hitting one of the cast round "knobs" just before the flywheel gets to the coils. Picture will help
– didn’t really check to see if the mag plate is warped. That could be causing the issues, but it doesn’t seem overtly wrong. I will need to figure out how to check for warping
– I have a few other plates to check fit – one from a 56 FD-10, one from a 57 Big Twin 35, and one from a 50-something parts motor. I would think I could check fit with one of those
– the cam appears not to be overly worn or cracked and fits snugly
– i will need to get my hands on it this weekend to check taper fit and the brass mounting rings
