no fire after sitting for 15 min , first shot puffs

[Chingis]

Howdy all just played a great game today but had some in field problems and was looking for a pointer to nail down the problem


1 gun shooting normal , then sits for 15 min and i have nothing , once i take hopper off i can manually push the bolt back like a 1/16 of a in and the valve resets , anyone know what this problem maybe ?

2 first shot often , goes with a puff and the ball flys out 8 ft , after that shot any balls shot quickly shoot fine , this need also to sit for a few for this to happen


my set up is

R/T pro custom , ule body , intella , x valve , lvl X , nitro duck adjustable 88/4500 set at 900

thanks you for any pointer.tips, or plain out just tellin me what do!

if you need lvl X info i can get it

Bolt stick,carrier adjustment. Up one I think

[ScatterPlot]

The first part sounds like a worn sear could be an issue, but I'm not sure.

[athomas]

You are getting bolt stick. The carrier o-ring is sticking to the bolt stem. To repair this situation you need to go one carrier size larger. If that causes leakage problems, then you will need to go with the next smaller/lighter bolt spring. Quite often, once the carrier o-ring gets broken in, it doesn't stick as easily.

ty for the help guys ,

im not sure that it is "bolt Stick" this happens when im not shooting at all, if i air the gun up, try firing everything is fine , now let it sit for 15-30 mins while still aired up and pull the trigger and nothing , now if i take off the hopper and manually push the bolt back i here a click and the sear rod comes back out to reset the trigger and it shoots fine.

note that the bolt does move but it wasnt fired so im not sure how that would be bolt stick? any ideas?

also im not sure if i said i also have the ULT

Thanks

What you are describing is bolt stick. As long as the gun is cycling everything is fine. As it sits, the carrier o-ring sticks to the bolt stem. Sometimes the bolt will move ahead(but not fire the gun) so that the sear is held down and the trigger rod will not come forward until you manually push the bolt back. Other times the gun will cycle but the bolt will not completely reset itself.

ok so I should be going down one spring , it leaked if i went to a bigger carrier. happen to know what color the bigger spring is?

\thanks

[CaliMagFan]

i'd suggest using starting with a really generic setup, that includes teh stock length spring.... get it leak free, and have the lvl10 at least work and all that...then modify one peice at a time.... once you get the thing to work with teh generic setup use the link in my sig to troubleshoot any issues it has.... hopefully there is some helpfull info in there... good luck... keep us posted..

If your setup leaked using the next larger carrier, then chances are, you are using the proper size.

It could be that the spring you are using is too stiff for your setup. The pressure in the valve before firing is too close to the tension on the spring to overcome any amount of o-ring sticking at all. By going to the next smaller spring you increase the amount of pressure differential between the air pressure in the chamber and the force of the spring. This pressure differential allows the bolt to be forced forward past any o-ring sticking issues without compromising antichop ability. Once the carrier o-ring gets broken in over time, you will probably be able to go back to the longer spring without issue.

The short spring is the lightest, followed by the medium red or cut spring, and then the grey high tension spring.

TY very much guys , my problem seems to be fixed , ended up just going to the smallest spring, and that fixed it right up, i waited 1 1/2 hrs and it still shot fine

thanks again

any guess on how many shots it will take to break the oring in ? ive shot about 1700 threw it last time when i was having problems with it.

[cphilip]

Should be broken in. Also if thats a relatively new X valve a lot of them have some really tight Regulator Pin assemblies. Causing them to sometimes stick after sitting. Once you break them free they fine for a while. You might want to pull that reg assembly out and oil it directly on the bunch of oring looking things. Until its broken in good these things stick a lot. Often causing non recharging issues and no shoot without leaks or even slow recharge issues and then shoot. Odd symptoms from this issue. Oil those regulators on those X valves. They need it.

[Chingis]

am i sapose to Oil or grease the regulator packing ? (when i was down at teh AGD HQ, they used a light grease on the packing)
your talking the one behind where you change the volicity correct?
im going out sat this weekend so i can try then for some field use, but untill then it seems to be workin.

[AGDlover]

no do not bother oiling the spring pack if you want to know what kind of grease that is call AGD but you should not have to bother that what so ever

[Auto_Rook]

cphilip.. thank you soooooo f-ing much~!!! i just got my x valve and i could NOT solve bolt stick.. oiled those things in the reg u told me too and it KICKS A-hole now!! thank you soo much. i was about to sell it too

Great to hear. Now beware that it might do it again. Untill it really breaks in good. Just do this... Each time you get ready to use it go ahead and oil that again before you air it up. Just to be sure. Until its well worn in. Its a simple thing and eventually it will break in. Seems these last batches have been extra tight. Several of the guys (Tuna and RobAGD) mix a paste with about half and half Dow 33 and Marker oil and use that instead. It stays on there longer. But oil will get you by and does work fine too.

And no I am not talking about the spring pack to answer the earlier question. I am talking about the regulator pin assembly.

The spring pack is greased just to keep it from rusting. Nothing more. And any kind of grease is fine for that. but its not necissary to redo that unless for some reason yours lacks any grease and its rusting. Or if you clean it for some reason. But any grease will do. I use white grease on mine. But any will do.
