Was wondering short of trying a different tank/reg what's the next best way to determine if I'm having a regulator issue?
Last Xmas I got a 62ci/3000psi tank with preset 800-850 psi Myth reg as a present from my wife so I could start getting back into the sport, after about 8 years on the side lines. At the time I had a classic valve and it seemed to work "ok" as long as I kept the ROF lower then about 4BPS. If I tried to shoot faster I would start getting shoot down, double feeds/ double firing, chuffing and ball chops. The faster I tried shooting the worse these problems and once I'd get to the point of trying to shoot say 10 BPS+ the entire system would almost entirely stop. I'm talking no real cycling of the action just little sputters of air. I replaced a few of the orings in the valve and the mainspring which didn't seem to help much and just limped along with it like this until my birthday when I got an x-valve.
After installing the x-valve I noticed I was having a lot of the same issues I had with my old classic valve. Granted I didn't try actually running paint through it but when I tried shooting it fast it too would stop cycling. I've tried tightening the reg nut assy no help there, I've also tried running tons of oil through the system and no dice. I'm figure it is safe to assume all the orings in the valve should be good as it is brand new. I actually went so far as to take the entire gun apart aside from the valve and wipe down and clean everything out. I made small adjustments to the trigger rod as it seemed to be touching the trigger when gassed just to make sure this wasn't contributing to the issue. When I tried firing the gun again I had the same problem. I did notice when checking the sear and trigger rod that the sear seemed quite worn and was wondering if perhaps this could be contributing to the issue? I also tried testing the level 10 with a dental pick handle and the bolt seemed to stop and vent air when hitting the handle and reset so I don't think the level 10 is part of the problem. The only difference I've really noticed with the x-valve vs the classic is when firing fast the bolt does seems to stick but will only do so for about 7-10 seconds before resetting on its own. It will also sometime make a slight hiss for 3-4 seconds prior to doing this. I'm not really sure what to do at this point, I considered trying to make minor adjustments to the level 10 just to see what impact that had but I don't want to end up trying to fix something that isn't broken and create more problems.
On a side note, I've noticed both my classic valve on off and x-valve on/off seem to have metal worn down around the edges of the on/off assy. When I took the gun apart I didn't notice anything in the mainbody that should be causing this but then again it is a really old mainbody(even has some rust in a few places) so I wouldn't be totally shocked if it was implicated.
