gun messed up...HELP

[ghost rider x]

when i screw my nitro bottle into my gun i hear a loud hissing coming from inside and i can feel air coming out the front when i don't have a barrel on. i checked my vavle o-ring and it seems fine. the screws holding in the valve and power tube are in tight. i can't seem to find the problem. i had just finished cleaning my gun and had not yet put oil in it because i can't find mine. i heard that some people had this problem and after they put oil on valve and shot it through asa it went away. if any body knows the problem and how to fix it that would be great because i am planning to play tomorrow. thanks

check all the orings, cupseal, and everything inside, make sure theres no dirt or dry o-rings, oil up and clean up the gun and it should work, if it still is having problems i would suggest giving the company a call and asking them about it.

yup thats the first thing. dribble some gun oil in your ASA, gas up, and dry fire a string of 20 shots. that should lube up any dry o-rings in the gun.
if that doesnt work, post back.
