What should the reg be set at? I haven't used it in a while and I don't have the manual. I increased the reg all the way up to 200 and its working now but I think the solinoid might be leaking cause I can hear air coming out of the back. Anyways I give up on this gun so now Im selling it with everything I have with it for $100 OBO including an extra reg, stock spring, broken solinoid, and everything else in the pic. The gun is missing a bolt on the grip.
