When are the valves considered down? When the small end of the rocker is fully down, or when the small end of the rocker is fully up? I know that when the mark of the shaft reaches the timing scale you are either in NO 1 position or NO 4 position, I just need to know when the valves are considered closed.
have the same problem?
