Question About The X valve

[TippmannGuy]

I have an ULE lvl X mag with an x valve and it was chrono'd out at 270 fps at the begining of the day and worked fine...
Until about 3 hours later it dropped down to 230fps and fired the response of the trigger dropped off.. later the marker would only shoot 1 shot then would refuse to fire for about 15 seconds then it may fire again? I did not adjust the velocity and i run a fixed output 850 psi tank and their was over 3k in my tank.

The only thing that changed throughout the day was the humidity was very high and temp was around 80-90 degrees. would the temp & humidity mess with my gun this much?

So is my X valve out of adjustment or should I try again and then adjust it if I have further problems...

When was the last time you oiled it?

When was the last time you oiled it?

should have mentioned that I oiled it before I chrono'd it at the begining of the day 2 drops down the power tube tip, 2 on the on/off, and 2 line that runs into the X valve.

maybe your lev.10 carrier is too tight. Try going up a size.

I would try running more oil through it. Mags with Level 10 like their oil.
