Valve problems

[Paintball_Kid13]

My on/off is F'ed /\ and this one kid said he had the same problem he said turn the velocity all the way up but if I do that it will leak out the back velocity thing, the small stainless cylinder pops up and leaks, thats what happens I run co2 if that matters I dont know ive watched the video looked at the manual and assembled it exactly as it shows but it still leaks anyone know what to do???

Slow down. Ok, where is it leaking from? If its leaking from the back, your velocity is too high.

Ok, replace your on/off orings. If its leaking when your using C02 then, you are getting liqiud in the valve.
