Ok so I bought a shocker from here off the nation, my first one ever. So I got it and aired it up no probs. Went to shoot and it was terrible, fsdo, broke paint and started leaking. Well
played with my trusty ear orgasming dm4 the rest of the day. Well come to find out when I reset the board I had the dwell at 12 ms and that was no bueno with the humphrey noid and he.....
So I reset the dwell to 17, and the abs to 10 and I relubed the whole gun with slick honey ( go ahead and hate it works perfect though :p) went out and shot a whole hopper perfect, except it had an intermittent leak from the body. Well I thought, its just the bolt sail like my dm4 and ill fix it easy. It turns out not so much......
I go out another day to shoot some paint to show my new beauty to my roomate and the leak is worse, not intermittent this time and stays till I de air it. Well crap, so I go in and relube her and try a new bolt sail, all new outer can orings, new front guide oring, new inner bolt sleeve oring and even a new front can oring. This was over the course of three days btw.
So none of that worked, im about to chuck this thing across the room because I know its the noid or manifold and I didnt wanna mess with those. But tonight I said screw it and performed surgery ( to me lol simple to some of you) I pulled the frame off and aired her up. Sure enough, slow and steady leak from the left exhaust manifold. So I carefully detach the eye wire and pull rhe scres out. I take the manifold off, clean all the orings and slap her back together. Air it up and psssssssssssss. Made it worse. Very defeated at this point. I go and goof off for an hour and decide to try again. I pull her apart, rub a tiny amount of grease on everything and put the noid back on. This time I make sure the noid is perfectly straight and I evenly torque the screws. Air it and bam..... pure silence....... I hate leaking markers lol, I prolly woulda stayed up all night wanting it fixed. Also I tryed a whole new bolt engine to make sure it was the noid. Just sharing my used marker story/ successful noid installation.
Gun waas leaking, replaced every bolt oring in gun and tryed a new engine.
Figured out it was manifold, tried to fix it once, made it worse, tryed again and it was perfect.
Happy camper over here, I always have bad luck with used stuff.
