Okay, at the risk of sounding like an idiot I was hoping someone could explain this to me. In a few other threads people explained a problem with the flywheel key "dislocating shoulders" and "pulling muscles". I am probably not thinking straight but what the heck does that mean. If a flywheel key drops out wouldn't the flywheel just free wheel? Wouldn't it be easier to pull? Help me out on this as I am totally confused.
