I have an older 68 classic with a rt valve and lvl10. The problem is when I shoot, the gun will start to go full auto, but it double feeds. I have changed out the ball detent from the metal to the plastic one. Also when I pull the trigger barely or pull it to fast the paintball will just barely roll out the barrel, which causes is to double feed( I think). My current setup is 1.0 carrier with the short spring and no shims in the lvl10. My tank is preset at 850 psi. I have tried different carriers, shims, springs, and another tank, still no change. PLEASE HELP! Need gun for Mancow event next week.
