Well I found out that the more I tighten the screw, the more I lose air seal. I guess maybe it's pushing the gearbox forward? I still have a perfect air seal, but I just have to keep the stock loose enough.
If anything, that'd pull the gearbox itself back. It might be pushing the piston and stuff forward a smidge.
