If your float valve, the little valve inside the nozzle, does not move forward (towards the muzzle) it will not close the gas system and start the recoil phase...no bolt moving backwards, no trip of the knocker, knocker stays forward and keeps pumping out gas until the mag is empty.
So pull your bolt.
- take a close look at the nozzle
- use a little screwdriver/pick/rod/fingernail and see if you can push the float valve forward...it should move freely, but there is a little spring tension..
- it should pop back when you let it go.
- if it's not doing that, take a close look at the o-ring on it, pull the nozzle apart and test fit it without the spring (don't shoot it like that, just test fit by hand).
The float valve MUST move freely and seal tightly when it's forward. I mic'd the specs of the valve...but it's in the workshop somewhere.
