Do Model A Engine Valves Rotate?
I'm curious, have searched the forum and the internet but didn't find an answer. But I would think Model A engine builders would know.
Do Model A engine valves, either stock or modern valves with adjustable tappets, rotate as they're operating? If not, what prevents them from doing so?
