Last summer I was having problems with intermittent spark on one of my SXLs. I checked and adjusted the point gap and cleaned with alcohol. I had spark while cranking, at least that's what is it seemed. It would sputter and run a little but then I couldn't get it started. Checked spark - no spark. Hummmm Pulled the flywheel again and my gap seemed tight and while I was watching and adjusting I noticed the problem:
