Hm seams that the last option is the one ;( I tried to turn down the velocity screw till the gun wan't cicle then the leak stops (but thers no air in the gun)
also i tryed replacing all the o rings stated in the trouble shooting manual. and tryed remowing the noid and all but still leaking. Calling dye tomorrow. It's sucha shame since its a brand new gun and my first expirience with dye
