old cj 258 running rough

My CJ started running extremely rough the other day. I drove it work jsut fine. But going home it wouldn't idle, and would die if I slowed down for the corners or came to a stop sign.

I've checked distributor cap + rotor, wires, and plugs, all which I just installed in December and show no signs of wear at all. I've taken the fuel filter out and run without it to test that, I've run seafoam through the tanks + carb.

I've adjusted the fast idle screw to keep it sort of running while driving it around, but am kind of at a loss as to my next (hopefully cheap) step.

The only thing I've found wrong is that it's about 1/2 quart overfull on oil.

I *think* I've narrowed this down to the cam position sensor a trip to the junkyard yeilded no results. Anyone got a distributor left over from an electronic upgrade?

an update for the archives. This turned out to be a worn lobe on the cam.

No, just the cam.
