I've had several different valves stick open on various rigs, but never ever stuck closed to where the cam action did not lift them when starting. On the model A, I KNOW from experience (when an oil pump jammed), that the starter's torque will take teeth off of the fiber cam gear if the cam can't turn, and that is why I say this problem is not a stuck valve.

But, I'm usually wrong when I'm sure that I'm right. Ha!

(Tom, I'd make a comment about Studebakers, but a valve on my Avanti tends to stick open every now and then... A little overnight soak with Sea Foam and it's right as rain. Done it twice now, same valve, #4 intake. Backfires and farts when it sticks.). Much more common on low spring pressure engines though.
