I purchased a used 80 gallon compressor for my garage about a year ago. When I first got it home and powered up, I thought there was a leak near the unloader valve. Dicked around with the unloader and broke it. ******* didnt recognize the crankcase vent right above the unloader 
.
That being said, I will need to purchase a new unloader valve. Currently, I have been releasing head pressure manually. But watching my compressor run, it looks like the flywheel unloader weight system (not sure what its called) that pushes on unloader valve to release pressure isn't quite working properly.
I get the general logic behind that the unloader valve does, but my compressor's operation doesn't seem right.
With compressor off, knub is fully extended.
With compressor running knub is sucked in.
Once compressor is running for about 3 minutes, the knub looks like it starts to oscillate in and out, which doesn't seem right.
If I pull the crankcase cover off is there anything I should look for? I did this once before, and if I recall, the flywheels weights moved freely.
Should I worry about the oscillating knub?
Much appreciated,
Kevin
