It takes quite a while to pump up to a max of about 90 psi (should be able to go to 125 psi). When I try to run tools on it, even ones well within the demand of the unit (sorry, don't have that info handy, but something like 11 cfm at 90), it quickly peters out, the compressor runs, but just can't keep up. The filter material is clear, actually run it without one to see if that was causing restriction. If I set the gage low, say 60 psi, it pumps up to it and stops, and will actually hold pressure, I did this and it held for 2 hours, so there isn't an obvious leak.
So the compressor has gone weak. Are these types of compressor's rebuild-able? It is craftsman, so parts should be available, just wondering what might be the cause of the compressor not having the power to do its job, worn cylinders maybe?
