Here's a new one to me, and I've been working with engines for a long time. I've done new coils/points/condensers/ on this motor and now it runs good (one one cylinder!) Upper cylinder doesn't fire, pulling the plug wire off when running does nothing. Not even any of the snapping you usually hear when you have the electrode near the plug. The weird thing is that I get almost a 1/2" blue spark jumping off the bare wire to ground when spark testing this wire. Its the top cylinder so its the one where the spark plug wire wraps almost all the way around the ignition plate and is almost 3 feet long, so I'm guessing its the wire shorting somewhere, though i'm damned if I can find it! New wires on their way tomorrow. Anyone else ever experience this?
