Got all problems fixed...but two

[Paintballboy]

Okay, I got my gun to stop leaking outta the vertical asa and valve, but know my gun has two new problems. First one. The gun looses pressure after the first shot and I gotta let it recharge for a few seconds. The secong problem is even with the velocity screw at loose as it can go the balls come out like a rocket when fired. Im using N2 now and it never did it before. Any help would be great.
Thanks

check the reg. seat and the spring pack......make sure the pack isn't seized and put some grease on it.....oil the reg. seat and make sure it's in the right place.

clean the inside too.

possibly a new reg seat would help, and it sounds like the reg piston, spring pack, or reg pin may be stuck. check and lube all of them.
