having issues with my biddies GX3 leaking down the barrel. when he gave it to me the reg had an input pressure of 550 which seemed very high to me, so i dropped it down to 350 (normal wgp cocker operating pressure) and backed out that stupid ANS IVG as far as it would go. i can hear that the main spring is still in there tight because when you shoot it with no air you hear the spring ring and can feel it vibrate in the grip frame. additionally to adjust the hammer screw you need to pull it back, so i know that its clearly holding the cup seal forward when its ungassed. i dont wanna jack the pressure up too high but it seems thats the only way it will fire without massive leaks after each shot.
main spring is a Green Madman spring, about to pull the valve spring out to see if it matches..... that could be my problem right there.....
Thank you in advance for the help or your confirmation that i should just jack the pressure back up
