I don't see hardly any movement of the crank when the impact is going on. maybe a 1/4 inch in 10 second. But it must be absorbing the impacts rather than breaking the tight bond it has.
..
a second question, I have been told that turning the crank backwards has some unwanted effects on the engine. More than unwanted, harmful. can someone explain what happens that is bad when the engine is turned backwards?
