classic leaking down the barrel

[florentine]

well i have a classic automag. it has a classic valve. it worked 2 weeks ago perfectly, i purchased an intelliframe and installed it correctly. i went to air it up yesterday and it held the air, i pulled the trigger once and it shot, then i tried to shoot a couple shots and the air went down the barrel. to get the air to stop, i had to pull the trigger and hold it. then the air stopped when the trigger was being held, once i let the trigger go, the air went down the barrel again. im thinking i need a smaller power tube spacer but im not sure. i can purchase anything you guys tell me to. so money is not an issue. thanks for your help

It could be that your power tube oring needs replaced.

Clean the PT o-ring and try again. Put a bit of oil on a rag, put the o-ring in the rag and wipe it down. The o-rings used in Mags are urethane 90 durometer and should virtually last forever. I would clean and oil the o-ring, check your PT spacer (it should most likely be a .220 or .225) and then put it back together and gas it up.

Make sure you have the correct number of o rings in the powertube, and in the correct order.
