Finally aquired enough spare parts to build myself a back-up gun, so I put in my ReTro valve to get it all tuned up. Immediately ran into a problem I haven't seen or heard anything about.
ReTro Valve
L10 Bolt w/ 0 shims
RT on/off with .745 pin
900psi input
When I aired the gun up yesterday it aired up like normal and would fire, but would recharge really slow and the trigger had what felt like more resistance than it should've had. The resistance was pretty even all the way through the trigger pull, remaining "under pressure" even after it fired.
Today I tried fiddling with it again. I checked all the orings in the valve body and the regulator and they appear fine. I cleaned off and re-greased the regulator piston and springs. This time when I aired it up I couldn't get it to fire at all. I could turn the velocity up until it would vent from the back but it wouldn't fire. If I degassed it while it was leaking out the back, then air it back up, it was leaking full auto style out the reg nut. Any thoughts on this, I am perplexed.
