I am sorry, i dont follow.
If i loosen the sprocket on the IP for the timing belt..how do i rotate the shaft if the IP? Seems like once i loosen the sprocket the IP will stay in position while i rotate the engine...as i understand this, i would have to guess, tighten it down and then go through the process again to measure it and see where the IP is in relation to the fly wheel.

Also, i am not even close to an acceptable range on the timing tool. I would like to understand that as well.

What am i not getting?

Thanks,
