Incorrect Timing Adjustment causing heat issues?

So talked with them this morning before I touched it. They clarified that yes the did mean misfire. They set the timing to a few degrees ATDC (somewhat arbitrarily). 10-15 degrees is out enough to cause an issue.
Adjusted it to 10 base seems fine but there is a slight miss that I haven’t tracked down. Dwell is good. Probably just the points. I have accidentally left it in the run position myself more times then I would like to admit.
