Gordon smith compressors

I fixed it. Ran a hot wire from the ignition switch to the coil.. took care of the problem. And that was after I rewired the complete compressor and still did the same thing. Go figure...

Our Le Roy 125 does that , try loosening the gas cap because it pulls a vacuum on gas tank,if u have non vented cap.

Well, then I'd be looking at the unloader system.

Depending on the model either all at once or sequentially, the valves on the compressor side are supposed to be held open.

So I'd guess during the rebuilt you either missed or wrongly installed those parts...or the signal to operate them isn't being generated by the pressure sensing system.

Yes it's builds pressure really good. Seems like it lugs down shuts off. As stated I can restart but shuts down again

Does it build any pressure?

Does it die as if switched off, or lug down?
