I made a piston stop that bolts directly to the deck. At first I just used a dial indicator on the piston itself, but quickly realized that there was about a 3 degree (guessing) period where the piston didn't move. So for best accuracy, I made the stop. I'm not sure exactly how far down in the hole the piston was stopping, but I know that it was hitting the stop 34 degrees on either side of TDC. Hopefully that made sense...



Doesnt matter how far in the hole it is... put the
damper on and roll it up till it hits and take a reading
on the damper.. roll it the other way till it hits
and take a reading.. split the 2 numbers.. thats zero
