    Air issue...

    RT ULE, xvalve, ult, lvl 10. Marker is with tech right now as he said he'd try messing with it. He says it may need the on/off shimmed more but isn't sure. The symptoms are; thread in the tank, fires for a bit, then stops. I unthread the tank, rethread it and it automatically fires once it's pressurized. Then I can fire a few more shots, it stops, and so on and so forth. I'll be ordering some parts from AGD tonight or tomorrow to just have them on hand in case I need 'em but was curious if anyone else had ideas. When I get it back I'll do a little vid to actually show the issue, too.

    Thanks.

    First off , what spring are you using ?

    Any one of these could be the culprit . Velocity may need turned up more . The on/off pin could be sticking in the oring . Just oil that oring or replace it (and oil the new oring) . Also make sure the front frame screw isn't too tight , that can cause the bolt to stick .

      Have you tried oiling it?

      Was it working fine and then all of the sudden started doing this? If so, have the tech replace the bolt spring. If you just got it you might want to tweak the lvl 10 and go ahead and just replace the bolt spring for GP.

      Are you using a 800+psi tank?

      Have you oiled it?

        I agree with the above... Oil it good. Oil everything inside and put oil in the ASA or macro fitting to the valve. It sounds to me like the pin is sticking in the ULT. Mine did that too. I pulled it apart, oiled it and put it back in. It wasn't engaging with the sear so it wouldn't reset the bolt. You COULD have bolt stick too, which is a carrier issue... The most realistic thing to me would be that the ULT pin is sticking, or you just need to oil the inside of the valve components.

          I'll be picking it up from the tech friday afternoon(since the field is open then). I had put some oil in the ASA..... that was it. I feel bad now lol. It was working fine, and it seemed to be a gradual thing. The first time it happened, I took the tank off and either the oring broke or I broke it. I thought that was it, got a new one, and then it slowly started happening sooner and sooner. The tech told me earlier today that it seems to work fine as long as I don't pull the trigger in all the way but I don't have it to play with so not quite sure the meaning of that. I'll need to pick some parts up from AGD or Tuna for ULT and whatnot as I got just the gun, no parts or anything. Also, the tank, I bought a 70/45 and it was working just fine like I mentioned. When I first noticed the problem it still had up around 3k left.

          Edit: Velocity was set around 270fps because of field requirements. Also, would like to mention that when the 'mag is repressurized, it automatically fires one shot. Then like I said, I'm able to fire a little more, then stops. Repressurize, automatically fires ones shot, repeat. Didn't know if that automatic shot was a symptom of the sticking pin, bolt, or oiling.

            That automatic shot happens when you press the trigger when the mag is degassed . The on/off is a minature valve , pressing the trigger opens that valve , then that valve is closed by air pressure from the tank . With the air disconnected , there is nothing to close the on/off . Hence when you air it back up , air blows right through the on/off and out the barrel .

            As for the trigger issue , first air up your mag when you get it back . There should be a small gap (about the thickness of a credit card) between the trigger and sear pin . If that looks good , liberally oil the on/off assembly . If it still sticks , you have a couple options which are replace the orings in the ULT , add shims to the ULT , and/or buy a shorter on/off pin ($8 from AGD or Tuna) .

              How many shims are in your ULT? Start with 4 and add one at a time until it goes full auto. Then remove the one that caused the full auto/uncontrolled reactivity.
              Except for the Automag in front, its usually the man behind the equipment that counts.

                With the degassed trigger pull you mentioned Guardian, I can understand that. I was firing at pretty good rates when I ran out of air every time and played with the trigger in a confused way each time. The tech txt'd me saying he thinks he fixed it, apparently it's not doing that now. I have another ULT kit ordered from Tuna(I bought the mag without any parts so i need some organ donars lol). Thanks for the ULT tuning info athomas, as I was curious about that for when the kit arrived. I wanted to try getting it super nice.

                Anyways, friday night will let me gas it up here at home and play with it some. I'll be able to take a vid of any issues I'm having, too.

                EDIT: Completely random from my issue but does anyone know the distance between the screw holes for the intelliframe ASA? I was wanting to call the local pro-shop about on/off ASA's and I don't know what fits our 'mags.

                  If you're talking about bottomline ASA that connects to the butt of the frame it is a standard set, meaning that any standard duck bill or ASA will fit as long as it is a direct mount.

                    Alright, so I got it back last night(the tech let me play several hours with is PM8 so I didn't take a vid last night or mess with it). My debit card fits pretty snug between the trigger and sear rod. I dont think the tech did anything tuning wise and I don't remember the trigger being that sensitive but now I wish it was operating as it should 'cuz that's awesome. But anyways, don't mind me taking forever to thread the tank in(i picked up a CP on/off but i want to get macroline before messing with that). As you can see, I thread it in and it fires, then I'm able to fire a couple more before it stops. The reason I was playing with the trigger after the shots is because if I hold the trigger in, you can hear air somewhere and if I hold it down long enough it goes away like it ran out(I'm thinking the air in the valve?). Anyways, I just wanted to go ahead and post this up before I mess with it. My ULT kit hasn't arrived from Tuna yet so I don't have the spare parts to tune the current ULT.

                      From what I have heard, and learned, when you pull the trigger to push the piston while the air is off, and then re-air it, it will fire because the valve is open when the air is screwed in, which then fires it and resets itself. It looks to me like this is what happened there because you pushed the trigger in the video while the air was out.

                      The other issue of it not firing appears to either be bolt stick, which is caused when the bolt is not pushed all the way back against the bumper. You SHOULD, theoretically, be able to fix that by using a different carrier size (bigger). First, to see if it is in fact bolt stick and not a piston issue, try pushing the bolt back with the barrel off using a swab or something long that will fit down the chamber. You should be able to push the bolt back against the bumper and hear it "click" when the sear reengages. This will reset the piston behind the trigger and make it ready to shoot again. If this is the case then the carrier is the problem.

                      I don't know what your PSI is set at, but if it is too low it will also not reset the bolt, regardless of the carrier size. Anyway, try these things out and see if they work. Hope that helps!

                        Definately bolt stick. Try a larger carrier size.

                        When holding the trigger after a shot, some of the residual air in the chamber will leak out due to the remaining pressure not being high enough to seal against the oring. This is normal for the level 10.

                        You can prevent the first shot when screwing an air tank onto the ASA by holding the trigger in.

                          awesome, thanks guys. the other night the tech and i were talking about the issue and other markers and he said you could reset the bolt by putting a swab down the chamber and pushing it back. now there's the issue, i dont have any spare parts like that and i dont think a ULT comes with it so any idea what parts i would need from AGD/Tuna?

                          oh, also, when i take the thumb screw out to slide the valve out, it doesnt come out all the way. it'll come out a little and be able to slide back and forth but it's like it's getting caught on something.

                          guess i could've read the lvl10 tech tips but i see that if the carrier is smaller(larger oring? kind of goofy like the discs on a supertrapp exhaust... anyways), then they say to oil daily.... which hasnt been done lol. i guess i'm going to drop some oil down the power tube and around the bolt. see what happens. if nothing, then ordering parts. Played around with it some more, oiled up a lot, put air in and it didnt fire automatically nor would it fire with a trigger pull. it's like no air was in it. i went to take it apart and i found out that the on/off pin is sticking through the body so the xvalve wont slide right out like it should.

                          mmm, a 3rd edit. anyways, when you guys say replace the carrier... does the lvl10 kit actually come with multiple carriers or can i get a shim kit like actionvillage has and shim it?

                              That's your bolt fomie. Re-glue it or you can just leave it out, not going to affect anything.
