what causes.......

What causes erratic misfires and rapid firing on an electro trigger, also gas leaks down barrel. Sometimes it mis-fires, sometimes it double fires then it also has tendency to run away. Tried replacing valve o-rings, same results, changed back to stock valve and stock trigger frame problem disappears. Its a hyperframe, do tou guys think it may be Supplied Valve or the rubber o-ring on the valve?

Hmmm...I'd say it was the length of the Centerflag supplied on/off pin although it may be the powertube spacer. Call Centerflag and describe the problem so they can send you a different size on/off pin.
