gun not firing

[gunangel]

Hey guys, I've got a little bit of a problem. I run a rt ule pro with the xvalve on a 72 3k tank. After about 12 shots or so the valve doesnt seem to get enough pressure to fire. The pin is still out put it doesnt actuate the firing mechanism. In order to get more shots I have to degas the marker and gas it up again.

Any help will be greatly appreciated,
THANKS!

you have oiled it at all or enough?does it leak or stay sealed?

change your powertube o-rings or lvlX carrier.

and, or oil it well and recock the bolt with a straight shot squugie when it sticks until/if it stops

[gunangel]

it's all oiled and it stays sealed and the bolt goes back, just seems like its (the pin behind the trigger) not getting enough pressure, I am running HP so I don't think low pressures a problem. I will try replacing carriers though

1) Add a shim or two to the ULT if you have one.

2) If you have a stock on-off assembly then you need to increase your velocity setting.

3) If the velocity setting is too now high, then you need to go to the next lighter bolt spring and set your velocity to the proper setting.
