| Re: Cylinder leak-down test procedure (with percentage gauge)
OK, I contacted the manufacturer and indeed, the instructions are in fact incorrect.
For those following this thread, the correct procedure is:
1) Bring the cylinder to be tested to top dead center, valves closed.
2) Thread the hose into the the spark plug hole.
3) Set the incoming air pressure to the tester at pressure 30-100 psi
4) Slowly turn the regulator on the tester until the percentage gauge reads "0". This calibrates the gauge.
5) Connect the hose from the cylinder to the tester.
6) Read the percentage of leakage on the gauge that previously read "0" when calibrated. This will be the percentage of leakage.
The instructions had step #5 before #4 and it made no sense to me.
