On occasion, I have witnessed where someone may have rebuilt a throat lift cylinder ram(replace seal kit) & did not re-pin the cylinder ram into the correct throat hole. K2's throat has two position holes for lift rams. So, a quick visual under the throat can confirm if this may be your issue?? I don't know if Ms have two positions? Just check it out.
Or, you can try either side's eccentric to compensate for unlevel throat. But like Tbran says, a bushing in the throat's pivot housing may be worn too.
This last month (October 2018), I replaced a K2 gleaner pivot bushing on its throat's right side. Surprisingly, my local AGCO dealership had the bushing in stock. Important note: the bushing has a full width cut that is located dead center in the lower part in it. It also has a grease hole that lines up with the pivot's grease zerk. To remove bushing, slip a skinny knife blade or thin screwdriver under either it's left or right lower side and pry upperward until you can grab that side with a needle nose pliers to easily pull it out. Remember to line up the new bushing's grease hole to zerk when installing it.
To get to the bushing though, you got to remove the whole throat. So - After removing all the pivot shaft's belts, sheaves, bearings, electric tattletail sensor wires, unhook/drop lift rams, remove the 8 eccentric mounting bolts (4 on each side), and disengage the return grain shoot, I used a forklift to lift the whole throat assembly, along with it's eccentrics & pivot shaft, and back it away from combine. If you can reach penetrating fluid onto the exposed threads of each of the 4 eccentric mounting bolts, it may help them from snapping off?? The lower rear bolts are the worst. I snapped off one of these on the right side. No worries though. Cause after you remove the throat from combine, you can get in there with a good long nose vise grip and turn the threaded end inward to remove the snapped bolt.
Once the throat is out in the open, you can remove eccentrics & shaft to inspect bushins in the throat's pivot housing. Check each side's bushing (one of each side - 2 total). If theres any shaft play, replace the bushing(s).
After you reinstall new bushing(s), slid in pivot shaft & eccentrics onto shaft. Then forklift the whole throat back into combine.
Each eccentric has 4 positions (clockwise:top,rear,bottom,&forward). When you reinstall the throat into combine, make sure pivot eccentrics are 180 degrees opposing each other (one side positioned down, one side positioned up). Then if the throat requires levelling, you can try adjusting from one side only.
