Does anyone here work on air compressers? I have a 5 horse Campbell Hausfeld which I just replace the motor on. The compresser runs fine till it start to build pressure then it stuggles to pump. I think it may have a bad check vavle. Do any of you think it could be something else? Like worn reed vavles or wiring too small. I would like to get this piece of [darn] working right so I can use my pneumatic tools.
