I want to verify an old 340 dampner is accurate. I have a piston stop installed and the dampner stopped at 6 degrees BTDC when rotating clockwize and at 7.5 degrees ATDC when rotating counterclockwise, I know the chain has slack backward so do I call this good. I really want to rig a dial indicator into the holetobe certain. The timing chain and gears are new
