OK so my bad luck with repairs is continuing. Im putting my VR2 back together. I have the first stage assembled and on a tank with 340psi. Air on--- nothing. I turn that adjusting screw down down down and can barely muster a slight hiss. So I plan to tear it all back apart and search for a blockage. If that isnt it, where should I go next. Im used to working on single stages because they are easy.
UPDATE:
This is what happens when you dont pay attention to what you are doing and try to force things. Had the brass pad been aligned with the first stage hole, I never would have had an issue.
