I can't be much help, but this isn't the forum for this question. You probably want to repost it in the Spyder forum. On my MR100 Pro the only thing I can think of that would, for some reason, leak air out of the adjustment screw is the o-ring on the striker being dried out etc.
Just looked up that gun in google images and wow, that is one sweet looking gun!
EDIT: Just read through my manual and looked at the leaking troubleshooting section. Could your valve bodies back o-ring need to be replaced?
