Hey, that's a neat trick!
I'm wondering if you measured the gap when it was home, and if it's close to the spec?
Seems to me like that should be the "optimal" setting. The factory spec would be an "average" setting. Could it be this would produce a better running engine? Are there any risks to having the gap too large/small if the spark is good?
I suppose you have to worry about things like dwell and bounce if you get to high RPMs, but this is a low RPM engine...
