X-valve Problem!

[wobbles82]

Urgent! I need to get this thing going in about two hours, so any help would be great help. OK here we go. The carrier setup is fine, always has been fine, until the other day. I got my EVO2 in and went out to fire some paint. I was getting shootdown within about...2 shots in a row. So, I decided to give a shim and try, and it worked fine. But I only fired a few paintballs, so yesterday when I went to play I noticed crazy reactivity, and near runaway mode! Whats up with this? From tank pressures of about 750-850, so thats obviously not the problem. Also, I even added two shims to give it a try, and that just made it more reactive. When I take out shims altogether, the mag doesnt even bother to fire. The sear locks into place and can be pushed against by the trigger but doesnt shoot or anything. Any ideas???

I'm assuming you're talking about ULT shims.

Install four of them and make sure that you have the field strip screw fully tightened with an allen wrench when you put it back together. Having that loose will cause excessive reactivity.
