Well that's an odd one for sure...too much compression seems an unlikely problem for a Model A engine but that is how it appears...

Someone told me once that when shut off an engine will probably stop turning when it comes up against the cylinder with the most compression....maybe #2 in your case....

See if it does the same thing next time if you loosen #2 spark plug....
