I've got a Quincy 325 turned by a gas engine. When it reaches 125 psi the unloader works both the intake valves and the engine drops to idle. A while ago the pressure started to creep up after reaching 125 and I need to stop it. It's gotten slowly worse over the last year. Took the valves and unloaders apart and cleaned them up with no change in the problem. I run this compressor for hours on end for breathing air and don't want to operate it if it's not working right. Anyone solve a similar problem?
