919.156610 has too much pressure on relief
I was just given this compressor yesterday. Owner bought it new,would pump up pressure but when pressure dropped, tried to pump but wouldn't run at full speed-I think is what he said.
He tried capacitors then was told that it was the check valve on tank from pump.This was years ago, hope he remembers correctly.
I got it to turn on but fittings on the tube from pump to tank were loose and leaking air.
Should I tighten and try or replace check valve.
Bad thing is he said relief valve was what someone told him was bad-too much pressure on pump to start up?????
