This should help a lot of people:

3 main things that are commonly overlooked:

1. Sometimes your ULT works, you just have too heavy of a spring. If you must, use the stock spring that comes with your gun. This problem occurs when you air up the gun and it doesnt leak, you can feel trigger weight, but when you pull the trigger nothing happens except a mild vent down the barrel.

2. A commonly overlooked thing is your mag eats lube like a fat kid at a chinese buffet. Each time you pull out your ULT to adjust it, always add a drop of oil on the two outside o-rings. I just helped tune a ULT over the phone today that was having problems with slow on/off reset. A drop of lube on all the o-ring proved that we overtuned and that it was in full auto. The symptom here was no leaks, but after you shoot once you have to wait a second or two and you can hear the on/off reset.

3. THE MOST COMMONLY OVERLOOKED PROBLEM: Make sure your back screw (the one that holds your valve on the rail and in the body) is tightened with an allen wrench. Hand tightening with make a perfectly tuned ULT go into full auto. Or if you tuned your ULT and its full auto, tighten the back screw. It sounds dumb, but it is almost always overlloked because you have to dissassemble the gun a lot when tuning your ULT or LVL X. NOw do not overtighten. Use your hands till its snug, then sometimes less than a quater turn up to about a half turn with an allen wrench tightens it good enough.


hope this helps someone
