Inner valve springs

Thanks, had me confused for a bit, but discovered there are 2 Schrader valves in the compression tester.
Gotta try and find someone local with an old hyd rocker I can weld to bar for compressor.
These 2 finger fresh aren't cutting it, not when there are 2 spring and a damper I'm dealing with.
Thanks!:thumbsup:
The schrader traps air in the hose/gauge, that means it only lets pressure out of the cyl., not in...just leave the air hose plugged on until that cylinder's finished & move to next.
