new unloader same problem
I put a new unloader and a pressure guage on the washer today. I adjusted it per the instructions but the highest pressure I could get out of it was 2000psi.It didn't take more than a few turns of the adjustment screw to get 2k but that was it. The motor seems to be laboring hard too. I kept turning the adjustment past 2k and when I release the trigger it kills the motor on a pressure spike. So I set it just under 2k and and it spikes about 200 psi but the motor keeps running. It will work as a 2000psi washer but it should be 4000psi. I need to check the motor compression before I do anything else. I will post back when I get my hands on a compression tester....
