xvalve leaks out the back

[dahoeb]

well i'm working on my friends xvalve, and normally i can get them up and running no prob. but this one is different! The air doesn't seem to be making it to the on/off, and it just leaks out of the little bleed hole before it reaches the on/off. i don't know what the heck it could be! bad on/off?

check the oring and try turning it down. if the fps is to high they blow out the back also

It could also be the reg seat o-ring. I had the same problem. Does the leak stop if you fire once and hold the trigger back?

hmm i'll check that on that.

think i figured it out, the on off valve pin is the wrong size, compared to my other xvalve, this one is almost half the length.....i swapped on off and it worked just fine. looks like i'll be ordering a new on/off pin
