Thanks Doug and Dan for the clues. Unfortunately neither loose wires
or low voltage to the coil seem to be the problem. The battery has to
jumped to start, but that's another problem I need to track down. The
engine runs, but poorly. I'm thinking I might have rust in the fuel
line that may have entered the carb float chamber and screwed up one
of the jets.
I'll be up early tomorrow to do some more detective work.
