The Ford Barn

1941 Ford flathead basically stock including 6V pos ground and generator. Made lots and lots of progress in the past year from being a real pig to drive to actually pretty good. No doubt this has been discussed extensively but my searches haven't been very good. I'll ask my Early Ford V8 club folks about this too.

Very, very hard to get the engine to crank when warm, easy when cold. In other words, the fuel and spark seem fine, the starter just won't turn over the motor when hot. I've undone and wire brushed all the electrical connections, including grounds, between the starter and battery. Maybe SLIGHTLY better but not much.

The whole point for me in having this car to have it like it was back in the day so converting to 12V is not on my list. Clearly, people started their 6V cars back in the day after they were warmed up, such as after filling up with gas.

Please help me out with a logical path forward to make the car crank when hot.
