leaking out the rear velocity adjuster

[kingpen509]

air is leaking out of my e-mag valve throught the rear velocity adjuster. its actually seams to be leaking out of the allen wrench hole.

any guesses or advice?

The velocity is turned up to high. Turn it down.
What spring do you have in the lvl 10? If you have the grey one in there, change to the red.

If it isn't shooting hot, Check your spring pack.
Degass the marker, and back out the adjustment screw all the way out. Take it off and look inside your valve. You'll see a black thing that looks like it has a bunch of washers on it, order a replacement and see if it works.

The spring pack would not be the problem. It would either be the reg piston or the reg piston o-ring. If you are shooting above 330fps, back off the velocity. If you are shooting under 300fps, replace the piston o-ring or the piston if the o-ring doesn't fix it.
