My engine was stuck from sitting for nearly 20 years. ATF down the cylinders,
and every day I would come home from work and try to rock it back and forth with a breaker bar on the crank pulley. After about a week it broke free. I then rotated it several turns to make sure that none of the valves were stuck. She smoked like a crop duster when I first got her running. Both from burning off all that left over ATF and the gummed up rings. But after while she ran like a top. For a "stuck" motor, it has great compression now. Never took the engine apart.
