I got my fastback about a week ago and since i got it things dont line up properly the vertical asa included with it didnt fit so i used my old one from my AIM bodied cocker. but when i got the gun totally put together i turned the air on and air shoots out of the barrel like their is no valve installed. i have tried a stock orracle valve and an eclipse supercharger valve with different springs but the same problem occurs.

cock it b4 you turn the air on

ive been workin with cockers for years i already know that

ok, do u have an oring on the valve? and is it seated corectly. The only way air is going to come out of the barrel is if your cup seal on the valve is bad or the oring is bad or missing.

i found the problem the chamber where the valve sits wasnt milled deep enough so air can flow around the oring
