now THAT makes sense! it stands to reason that if damp weather is a problem, it's more likely to be interfering with the spark than with the fuel (not to mention the fact that if it's in the fuel, the problem won't go away when it's dry). i'll bet it was something silly like that, poor shielding of the electrical system from moisture. the 59 flathead is a 12 volt system from the factory, so that will hopefully give some advantage. i've been told i should switch from generator to alternator, but i haven't made up my mind just yet. i'll probably have to, though, if i want to make the fuel injection swap.
