Default Re: I’m wondering if my coil is going bad

Does anyone have any ideas about why point gap would appear to “slip?”
Check the distributor cam's surface, it should be extremely smooth, if it's the least bit rough the point's rubbing block will wear down quite rapidly.

I had this a couple of years ago, I had put a new "B" cam in the distributor and never thought to check it's surface. The point's rubbing block wore down in less than 50 miles. I took the cam out and polished it w/crocus cloth, it's been fine since then.
