Mag chuffing

[shooker8]

I got a Pariaha ule mag with a X-valve and lvl 10 and a ult. I cant seem to get the gun to shoot reliably. It's chuffing and not recocking. I'm using the gold spring. When i play with the back screw tightening and loosening it will recock and be able to shoot but it only lasts a few shots. I tried to equalize it and need some help here guys. Thanks

Are you using a hp output tank 850, do you have more then 1000 psi in the tank, use the loosest L10 carrier that doesn't leak, use oil before gassing it up, make sure the ball detent isn't in to far and has the proper size o-ring on it....

I'm using normal output 850

What flying said. Largest carrier that doesn't leak.
