Coils, condensers and points are only a couple of years old which doesn’t mean they can’t be bad. I did swap plugs but the problem stayed with the bottom cylinder. Point gaps checked .020 and .018. I realize weird things happen but wonder how the ignition system seems to work well at high speed but not low speed. Never the less it seems like it is time to pull the flywheel and look around and maybe swap some components.
An old mechanic suggested a leaking seal such as the lower crankshaft seal which might lean out the lower cylinder under some running conditions. Any thoughts?
