Well I have a 2100 from a 74 J-20 in need of rebuild on my truck and a 4350 from a 77 J-10 at my folks house. I'm trying to figure the better of the carbs for my wheelin rig. My question, who likes what they run off-road? I had a 2150 on my 84 J-10 (similar to the 2100 I believe w/altitude compensation) and I never had many stalling or idling problems while off camper. I'm also a poor student (cheap a**) and thinking about the cost of a rebuild kit vs. intake gaskets.
Thanks in advance, Marc

I run a 2150 on my CJ and LOVE it! Great idle, good power (for a 6), and great off-camber performance. I have only had a stumble on a steep, continual nose-down trip i.e. 45 degrees for 30 yards or so.
Hope this helps!

My chero came with a 4350, it kicked Great Googley MoogleyGreat Googley MoogleyGreat Googley Moogley offroad. The super small primaries gave great throttle response at low throttle and it never once stalled on me. But on the HWY it got me a wopping 7-9mpg :(

4350 - used it for years and NEVER had probs with it - even on super angled stuff. But the 4350 and the 2100 require different intakes...you knew that right? :confused:

If your engine currently uses the 2100, stick with that.

It's not worth it to put an adapter on to run the 4350. The only other choice is a full manifold swap.

The 2100 is good off road and a rebuild will be easier than a manifold swap.

my motorcraft carb has been good to me... i would upgrade it for fuel injection... but i doubt i would swap it for a 4bbl.. .and if I did, I would probably get a rochester quadrajet... but I'm a rock-oriented guy..
