The gun airs up nice, slight leaking from bolt. sounds normally when it shoots but the ball only goes 10ft. I dont really care if it doesn't work is my crappy back up. I just would like to know whats wrong with it.
take the gun apart, and clean and check the valve. Also while the valve is out check to see if the plunger slides in and out of the valve without binding or catching of any sort.
Also tear down your reg and clean it.
Lube the Reg, or unscrew the reg, and you'll see the black thing that the reg screws in to. unscrew the screw or the black thing and take the valve out. lube it and make sure the firing can is on the spring.
