CLassic Valve Problem

[Darkknightheven]

Hi Guys, i got a problem with my classic valve...First, when i tried to install my level ten everything fit into place but when i gassed up the marker is began to leak out of the back (where you change the velocity)...Any suggestions??....Also, SOMETIMES when i try to shoot rapidly with the regular guts inside, it has an extreme velocity drop off every 3 shots...I fixed the problem by just taking apart the gun and moving that little spring inside around...Is it just sticking?...Please Help!!

have you checked your velocity? If it's too high, turn it down. If the velocity is ok you need a new reg piston.
