make sure your tank doesn't have high output pressure, also try replacing the back cap's o-ring and lube the inside of the bolt not just the outside.
i also agree with Anthony

EDIT:check the 2 o-rings closest to the rear inside the gun make sure there not worn are dry rotated in any way

You can use an ASA with a gauge on it, but it doesn't matter. Your tank is most likely high pressure, and the G4 doesn't care either way. The majority of people with G4s use HP air anyway.

With the gun de-gassed, take off the back cap, and push the bolt forwards through the breech. Then, put the back cap on, and turn the reg all the way down. Air up the gun, and slowly turn up the reg until the bolt sucks back. Put dwell at 12ms to start, and if it shoots, lower it by one increment until it's inconsistent or won't shoot, then bring it back up one increment. If, at 12ms, it still doesn't work, increase the dwell by one increment at a time and see if anything happens.

I think he means is it is letting more than the normal HP output. But I would figure it would blow a disc...

I forgot to mention that once the bolt sucks back, you've got to give the reg another half turn or so. When the bolt sucks back, you know that at least there's air pressure getting to the gun, and it helps to combat the bolt stick. However, it's still not quite enough pressure to make the gun cycle, even with the right ammount of dwell, so don't forget to open up the reg a bit more past that point.
