Next time I try to break it free I'll loosen the screws. Last time I tried to break it loose I couldn't seem to get a pry bar in the flywheel teeth that well, and I was just out looking at the engine now and saw two empty holes on the pully on the front of the engine. If I were to put 2 grade 8 bolts and use a 5ft breaker bar would that be too rough for the engine?
