X-valve runaway

[kopfjaeger]

I removed the ULT from the X-valve and installed 3 different Retro on/offs. When I pull the trigger, it goes full auto. Every time I changed on/offs, it did the same thing. Any ideas? The on/offs were stock and taken out of retro valves. :confused:

Are stock X valve on/offs different than Retro on/offs?
I am using a preset tank @ 800

that sounds natural to me. lowering the pressure would help, or you could just leave the ult in it.

The on/offs are the same. Be sure that you have both the small and the larger o-rings on top of the on/off.

ULT prevents me from shooting fast, so I am going back to stock.

Thanks again Shawn. Now, what size pin should I get instead of stock?
