Creek,
I think your problem is at the cartridge carrier. They recommend that you do not take these down as they are a B!! to adjust. Get some snap caps and slowly cycle the action. Get a dental pick or something to correct the alignment of these carriers, then tighten down the screws. (There's one on each side of the action, just above the loading port). When everything is "working, lock everything down with "blue" locktite, and do not remove in future disassembly.
