Twice I've seen distributor bodies short between 3 and 4 and cause a misfire.

Last weekend I helped a friend get his old Honda 90 three wheeler running right. It would start and idle, but quit after running a couple minutes. Normally this would sound like a lack of fuel problem, but in this case it turned out to be a fouled plug problem. Normally a fouled plug clears up after getting hot, but this is the first time I saw a fouled plug get worse as it warmed up. Anyway, a new plug had the Honda running perfectly again.
