Because I had the other one leak a short time ago, I can tell when the gauge spins easily. These teeny o rings flatten out easily I have extras. When l get this done I have a clean bucket of water to submerge it in to test everything.
Huben k1 Air leak at front gauge, cannot get the cap off. It is held on with balls and springs inside, Appears they want us to replace the whole thing ! Any one ?
Got the Huben back together ,The only ammo I shoot now is 2.19 dia.zan slugs they fit tight no slipping out And gotta keep the pressure up to 170 so it indexes solidly.
The bushing came out when i pushed the firing valve out to the rear, at first i thought it was the firing valve seal , nope too small then i matched it up, weird thing to happen.
