best offroad carb?

When I first got my Jeep, about 5 years ago, I rebuilt the bbd, and did the Nutter bypass. The old 258 ran pretty good, and didn't sputter too badly on extreme angles until recently. It's not idling very well, and basically needs a rebuild again. Rather than do that, I think I'll just replace it. I know that fuel injection is the way to go, but I'm poor, so another carb it is. What are you carbeurated guys running, and what kind of luck have you had with them? I'm thinking either Motorcraft or Weber. Which is the best, strictly offroad? Thanks,

Jer

Re: best offroad carb?

Best luck I've had is with the MC2100 1.08 mounted backwards.

But I'm kinda backwards. [img]images/graemlins/grin.gif[/img]

Re: best offroad carb?

I'm partial to the 2100s also...mine runs at angles that made *ME* choke out [img]images/graemlins/blush.gif[/img]

Not to mention you can field strip one in 10 minutes (including removal), new parts are cheap and on the shelf (even at AutoZoo [img]images/graemlins/smirk.gif[/img]), and any 3rd grader can figure them out (even when put on backwards [img]images/graemlins/shocked.gif[/img] )

Re: best offroad carb?

The MC 2100 seems to be the concensus on every Jeep forum I've ever seen. They ARE easy to work on and troubleshoot, and you don't have to find a truck in the junkyard to get one. They were on plenty of cars too- got mine off of a Ford stationwagon for $20. The venturi size is on the driver's side of the bowl in a circle. Make SURE you find the 1.08.

Re: best offroad carb?

It's probably not what you're looking for, but after fiddling some, my Carter YF 1-barrel is working like a dream. It idles under 500RPM, pulls smoothly from there, has very good throttle response, and has never been upset by any slope I could get on. It surely produces less power than a 2100, but it does make all I've ever needed off road.

Motorcraft 2100. Mine would idle and pull at low rpms on severe angles that caused power loss with the carter 2bbl. This is referring to a nose up angle.

But don't go with the Holley Pro-Jection. It just doesn't work that well.

Isnít that a reliability issue more than a performance issue?

Seem to remember reading bad things. Components that have issues and maybe poor choice of profit margin for the marketing effort.

Both.

So far the tally is 3 injectors, 1 TPS and 1 fuel pump. Occasionally, the injectors leak out the top in the mornings causing it to flood. It never seems to be adjusted right. I have the box sitting on my center console to adjust the mixtures when it decides that what it is set at isn't good any more.
