I need help PPS Super Stocker

[Erndogg]

Getting my gear ready for this weekend, and for some reason my super stocker has gone awry.

Every time I screw a 12g in, I can fire 3-4 shots and then the rest of the 12g just flows out the end of the barrel. I checked all the rings I can and every thing looks fine. I oiled it up, and every thing.

I can take every thing out but the valve, as I don't have a valve pulling tool. I just sent it to palmer's back in April and its worked wonderfully up to this point.

Ideally I would like to have it running before this weekend, as one of the guys running in my crew wants to use it at BFSV game.

Any help would be awesome thanks.

Air down the barrel = air leaking past the cup seal.

1. The cup seal is worn/misaligned/dirty/etc. Without a valve tool the only thing you can do is oil it heavy...PPS guns drink oil.

2. There is no spring/a broken spring in the valve, this could make sense since the CO2 pressure would keep the valve shut for the 1st few shots. Remove the hammer and push the valve pin with a dowel to make sure it springs back.

3. Unbalanced springs causing excessive pressure on the valve pin.
