Chasing my tail trying to get 1928 tudor running

[Tom Wesenberg]

Wisconsin air cooled V4 engines used on swathers are famous for exhaust valves sticking during the off season. I saw one snap the camshaft in half from a stuck valve. I have a Renault Dauphine with a stuck valve, so the crankshaft will turn, but not 2 full revolutions. Valves can stick in any position, and I wouldn't force it too hard if it's stuck.
