Another ULT Problem!

[wahoo5x5]

I just put my x-valve in with the ULT it came already installed . When I fired it it goes rapid fire, so I start to take out shims one at a time..all the way down to no shims... still rapid fire.I have a Crossfire tank fixed at 800 to 850? Ant help would be very helpful! Oh yeah it also fires once when I first gas it up.

Thanks,

pics would help

and 1 shot after gas up is normal operation..

PIctures of the ULT the whole bolt???

[mostpeople]

ULT assembly, trigger assembly (do you have trigger stops?)

take the ULT out and take a pic of the hole in the valve where it goes also

mainly the ULT assembly need a few good pics of it

and a pic of the marker as well..

Oh yeah no trigger stops and a level 10 bolt.

Hrmm, do you have the little black o-ring on the pin?

Im trying to think of what it could be but im stumped... are you sure about your tank output psi? The reason I asked about trigger stops is, is it possible on the RT that the sear trigger rod is too long and is being bounced back by the trigger hitting the frame?

Your reg looks like it might be a tad far out, maybe screw it in a little more to see what happens, sometimes when the pressure is too low the gun will do many rapid fire shots but at low fps..

One thing I notice right off the bat is that you have a lvl 7 bumper, blue, not the clear lvl 10 bumper.

They are technically different however many AO'ers use the blue because it lasts longer. The lvl 10 is more gummy like affecting the bounce properties on impact. So, if we cant find any other obvious issues you should start by getting a new bumper - however im doubting thats it.

Yeah that little black o-ring is their..uummm I did notice that when I gas it up the sear rod is right up against the trigger, and I'll see if I can find the out put pressure for the tank online.

nono, you need to check it for yourself, with a guage.. just take a HP guage capable of showing 5000+ psi toss it on your ASA and plug the other side. It will show you your pressure.

I think the issue could be that the rod is right up on the trigger, thus when it RT's back foreward it bounces off the trigger and fires itself again. The next step is to screw in the trigger rod at the clevis on the sear and see if that doesnt resolve your issue.

[athomas]

Your problem is most likely caused by a worn sear or a bad/leaking on-off oring. The oring problem could be as simple as a piece of dirt caught somewhere. Is your valve tihgt in the body when you are using the gun. Another thing to check, is the presence of the rail bushing. Sometimes they get lost and forgotten about.

Ok I checked on the tank the out put PSI is 800. I also ajusted the sear so the rod was not on the trigger, and the same thing happens...full auto! do you think the rt rail is the issue?

I have not check to see if their is a rail bushing,,,not even sure if their was ever one in their bacause I bought it used...when I had my old level 7 valve with level 10 blot on the rail everything worked.

[athomas]

If it worked with another valve then the problem is probably vavle related. I would change the orings in the on-off top area. Only the top 2 cause those types of problems.

[flyingpootang]

athomas is correct. Usally F/A is caused by the on/off pin being to short just like to many shims in the ULT will cause F/A.
