When you gass the gun up and it leaks does the bolt start to come forward if it does its a solenoid problem may be a bit of dirt in there take it apart and clean it .
If the bolt does not move but stays back then the solenoid is ok .
This is because the solenoid holds the gas back from the bolt until you fire the gun when you fire the gun the solenoid opens the gas to the bolt and the bolt moves forward when the firing cycle is finished the solenoid shuts the gas to the bolt and opens the hole at the bottom of the solenoid to expel the gas behind the bolt making the bolt come back.
If the bolt does not come forward then its proberly as RainbowShooter sugests screw the velocity adjuster all the way in give it a little nip then fire the gun a few times you will hear the gun firing but nos gas being expeled then adjust your velocity as normal this 9 times out of ten cures this problem which proberly arose when you dident push the Poppet back all the way in when you took it apart.

I was on to Kee and they said its probably a stuck solenoid or something or other! Took the gat apart but cant inscrew the damn solenoid to have a look at it!!! Its never simple is it?
