Leakdown Testing

Have you been able to verify your TDC is correct. If it would have slipped that would throw off your timing which could possibly be your miss. Not sure just taking a WAG.

I have a related question that has been keeping me up at night for years, LOL. When using a twin gauge setup, do you set the incomming gauge to 100psi before connecting the cylinder hose, or do you adjust after connecting? The reason I ask is, if you set it before connecting, the reading on the incoming gauge drops slighty when connected. Chuck

Mine is supposed to be connected and then adjusted to 100psi then backed down to 60 psi before disconnected so then when connected to next cylinder it starts @ 60 psi
