Question 1983 CJ5 wont run right

I have a CJ-5 1983 258 inline 6. This thing will not run worth a dime. Thinking of taking Carb. off and swiching with a 1979 model carb.. Take the 100 yards of vac. lines off and junking all vac. components that are there. Is this a good idea. I have spent way to much money on this motor. The jeep runs good when it wants to but floods out all the time. I have put 411 gears, 1 piece ax., detroit locker in rear. just need motor to run.

Does it have the 2-bbl Carter with built-in stepper motor? I know my brother's '85 CJ7 with the 258 has the same setup as my '90 (the above mentioned Carter and the electronic emission controls) and we did the nutter bypass on it to clean up everything that you mentioned. Just do a search on here for "nutter bypass" in the CJ and YJ forums and you'll find a whole bunch of info. If you have to keep emission equipment for your area, the carb may simply need a rebuild (about $12 for the do-it-yourselfer) and although it won't get rid of all the vacuum lines, it may run much better. One important thing, based on the age of your jeep, the stock carter carb may be worn out--they leak air around the throttle shaft with time. I got 130k miles out of mine with one rebuild at 80k miles, for reference. (personally, i'd replace it with a weber, as evident in my sig, if necessary--much less temperamental).
Currently an '86 CJ-7 and a '77 CJ-7 Golden Eagle---#4 and 5 following a '01 Sahara, '90 Sahara, and '85 CJ-7....

I would look into a weber carb. My father got one for his 85 and he hasn't had a problem since. It was a few bucks but it sure is worth the money!
