Leaking air somewhere. Changed valve and it will not hold air. Did get some leaking through barrel but also around fill port. Need help. Thanks
ThanksLeaking out barrel muzzleView attachment 451172 and breech (when side-lever open) means broken valve core (picture.) If you've replaced valve, did you burnish new valve to valve seat? Best illustration of burnishing is Hajimoto's YouTube on installing performance kit in Umarex Gauntlet.
