4hp 20 gallon charge air pro slows down
by Richard Breig
Starts fine but after about 30 seconds or so it slows down until the motor stops and then I assume the heat switch in the motor pops.
Wait a few minutes and it will do the same thing.
I took the regulator and gauges off to see if it would run and it did fine but as I cover the pipe and it starts to build pressure it slows down and stops.
