Right at that "pack another BB into the chamber point"....gently-ish (so as not to bump/disturb things) pull the bolt.

Is the float valve stuck forward in the nozzle? Flicking it with something pokey...does it get it moving springy-ish again?

Check the oring around the float valve for nics/deformation...check the inside of the nozzle for chopped BB's.

The valve should spring back and forth...back = gas released down barrel pushing BBs...forward = trap gas, start recoil/load cycle.

The valve should start back...flick forward and spring back without sticking.

Maybe I got some loctite residue on the o-ring when we last assembled it....take a close look.

**EDIT**
OR...remember how we were trying to set the velocities so low the other night and I said, any lower and it might not cycle properly....try moving the whole assembly up...so the valve starts a bit further back (i.e. more power). About 1mm. This may be due to temp variations.
