I have had this compressor for nearly 20 years and it has run well. I just noticed that I can't get the compressor beyond 80 psi with the regulator fully turned to the + side. It will hold the the pressure and overnight drop about 20 psi as it always has done. I hear no leaks. It does seem to take a long time to get to 80 psi.. Any ideas??Thanks
