Power tube question/problem
So my mag leaks air as soon as it's gased up. Pull trigger and hold it stops. let go and it's almost like I have to flick the trigger to get it to reset. Still leaking and sometimes chuffing(almost like an rt effect)the whole time. The o-rings in the power tube were replaced and still the same thing. I swapped valves into a know working gun and same thing. Not sure what to do. Are there different spacers or shims for the classic valves? Any tips or tricks to get this thing running?
