Symptom: after start up, builds pressure to 1300 psi then a loud sputtering sound without rpm loss, followed by periodic loud "popping sound" like a gunshot. I then immediately turn off. It is reproducible Seems to come for 2nd stage but uncertain.
Electrical 3 phase w autostart, autodrain, no interstage gauges.
Recent valve overhaul on all stages.
Any ideas or troubleshooting tips?
Thanks
