Stripped down the entire gun..

Right now it has a small leak from the lpr set screw, Noid is responding but not fully cycling

Dwell has been checked to make sure it is stock and I have replaced the battery several times

LPR is at 5 and reg is at 3 still doesnt work. Bolt moves freely outside of body

If you have a leak from the LPR set screw, then one of the outer LPR orings near the set screw is bad. It may not look bad but swap them out anyway.

A leaky LPR will not be able to maintain enough pressure to cycle the gun.

Make sure you don't have the front on/off knob in the off position as well.

LPR leaks can be a few things..

like mstrkey said change the other LPR orings should be 013. and make sure its not at the LPR set screw itself if it is then take it out and locktite it with blue lock tight.

and if both of them fail u'll have to replace the 007 inside the LPR body

while you're in there i'd check the LPR retaining screw seat, its the black hocky puck looking thing on the brass screw make sure it's not beat up or indented too bad if it is just replace it..

same for the piston oring
