Seems I have another problem to deal with too, found lots of oil in the air filter.
You have the Carter carb with the pulse air system. Those carbs attempt to monitor the exhaust air, intake air temp, air/gs mix and adjust the carburetor for you. The pulse air system pulls air from the catalytic converter and the manifold through two tubes connected to the air cleaner assembly. It is a poor system at best and is greatly affected by altitude, type and brand of gas, and ambient temp. Quite often when the jeep is not driven for long enough distances moisture collects and condenses in the pulse air tubes and picks up oil from the engine. It will pool in the air filter housing and ruin your filter. There are a number of ways of getting better performance, but the least expensive is to change to a High Energy Ignition system and change to a different carburetor, like the Motor Craft 2100.
However, your state may not allow you that option. I suggest you check with local officials before changing anything under the hood.
