Another newb question

[HEADSHOT]

I am having a gas problem...
I a using c02 until i can get nitro, when I screw the tank in i can shoot one or two times before the gun either does nothing at all, but stops shooting, or starts REALLY leaking out the barrel, and stops shooting.

Is this just because i am using c02, or is my gun screwed up???

If you have level 7 then check the powertube spacer(see if you need a different size), pt o-ring, or spring these parts might be worn out.
