258 w/Carter BBD running rough

I'd got an '84 258 with the Carter BBD (High Altitude). Most if not all of the computer stuff has been axed or bypassed by a DS "mechanic" I had replace the valve cover 2 years ago but it's always started and run 100% fine regardless.

Two days ago it started to run rough at idle and stall every time I come to a stop. I thought I had bad gas so I added carb cleaner to the tank, new fuel, changed the filter and cleaned out the carb with an entire can of carb cleaner but that only seemed to help just a little bit.

With the way it's running is this one of the failure modes of the Carter BBD? What can I do to get it running good again?

This is on an '84 AMC Eagle but it's the same system as the CJ/YJ/SJ.

Thanks!

Drilled out the idle tubes and flossed them out. Runs great now.

Totally. If you're careful you can even do it without removing the entire carb but I did just to be safe.

I've been driving this one for 4 years now and it's the first issue I've ever had with the BBD.

I can't remember all of them we did on the 258s at the dealership back in the day. Pull the top off, lift out the tube assembly, drill, flush out, go back together.
