I've got a strange one. My 73 is pretty stock. It does have an aftermarket crane ignition, but I can't see how this would cause the following problem. When it hasn't been started for a few hours, and the engine is cooled to the ambient 90 degree air temp, the first two or so times you turn the key, the starter behaves as if it isn't getting enough power. It sounds like the battery is almost dead, and simply cranks slowly. On the third try, the starter cranks normally, and the engine starts fine. If the engine is hot, this problem won't happen. I've read up on cleaning the electrical connections between the battery and the starter, done that, no change. I'd really hate to buy a new starter and still have this problem, but that seems to be the next thing to try. Any thoughts?
