JTS Jts airicuda standard problems

Hi is there anybody out there that could possibly help me out with understanding why when I start filling my gun air leaks out the barrel? And Ive done it while I have it cocked as well.

when I have the lever back air shoots out the mag well side as well as the front of barrel.

O rings seem to be all in I did have a problem with my valve pin but I epoxyd and taped my valve pin back together and it seems to be working as it sould I just can't get a fill.

When I turn my power adjuster down (jts airicuda standard) the air seems to move slower thru the barrel. It's almost like the air is just passing right thru the gun how can that be? Anyone?
