So I picked up a LNIB Karni that the guy bought brand new, put less than 100 shots on the counter becuase he couldnt get it to shoot properly, and stuck it in his closet until he sold it to me last week. I figured it was all well and good becuase Im pretty familiar with the format and could figure it out with some help if needed, but Im not sure what to do next. My tank output is correct, I attempted to sweetspot but the velocity is really really all over the place, all settings are reset to factory fast, but it farts! Like a slapped together sniper. Im a little perplexed. Ive had a good number of e-cockers, but I havent had this issue before. I'll make a video tonight. Im not sure if my bolt is in too far or not far enough, but it seems to be in the proper location. Any pros out there wanna help a brother out?



And yes, I searched.

Maybe ivg isn't in correct location to far in or
Out. Or needs new springs

About how many rotations should the IVG be from flush, assuming the karnivor is fully stock. I know its not an exact science but about-ish how many full threads in?

[PaulE2Cocker]

I know on my other cockers it's 1 1/2. To 2 rotations in if it looks further than that could be your problem

Well, if it's been sitting maybe the first thing I'd do is strip it down, and clean/lube it all (including the HPR). In a pinch, throw some oil in the asa and fire a few shots. See if that lubes/loosens anything that is causing your problems?

2 threads visible at the back of the gun.

If you have a gauge set the HPR to 280 psi.

adjust the LPR and you should be good to go.

i ran my karni with the ivg about 2-3 threads in and had no issues. put a generous amount of oil right into the asa and dry fire it a bunch. or the hammer or valve spring might be worn out, it could have sat cocked for a long time or something.

lug slip or wrong alignment. Plus for it to fart must mean it doesnt re cock correct? maybe check the lpr too..

Usually, farting comes from an imbalance between the hammer and the operating pressure.

Get a gauge for your inline reg and set it to 0, then slowly up the pressure until the farting stops. You shouldn't need to exceed 325psi. 285 is a good target.

Once you've found a comfortable pressure, adjust your FPS through your IVG. It's not the best way to get efficiency, but your marker wont sound like a clown car.

Chances are you just have to bump up your pressure a bit. If that marker ever sat for a long time with the hammer cocked, the spring may be weak.

Oh, and just for the hell of it, set it to classic mode with your LPR set to 0. Hold the trigger and up your LPR until the backblock hits the back most part of it's cycle. Then add a quarter turn up, just in case.
