When you're putting the torque on those flywheel bolts necessary to tighten them to specs or to get them loose, you can bet your buns that the crank will move, no matter what the compression. You will need to lock the crank somehow to break them loose or tighten them. I just remove the inspection plate and stick a big old ccrew driver into the starter teeth to hold the flywheel still while I do the bolts. BTW, use Lock-tight when installing and always use new bolts.
