2 barrel carb replacement

I have a 88 YJ with the 4.2l. My carb is now idleing rough, at speed it's ok but the idle jumps. It has a new jasper motor with about 5k on it. I've been reading actually seeing videos of guys running Mopar 2bbl carbs. Everything I hear and read say its a far better carb then the stock one. The only problem I am not seeing which carb to buy. I already took off the electric choke on the stock on and I want to stay with a manual choke. Any help and advice is greatly appreciated.

Check this out. Very common problem, and easy fix.

Make sure your intake manifold bolts haven't loosened up, too.

Cool. Cheaper than a replacement, huh?
