Carb ???

Hey guys,
Anybody got any experience with either the Holley/Offenhauser combo or the Weber in off-road/off camber area? My CJ-5 has a 258 6 cyl. and I want to upgrade, but I really can't afford the fuel injection thing. It will primarily be for daily transportation and rockcrawling on the weekends, hard to extreme trails.
Thanks,
Mike

Re: Carb ???

Consider the swap to a Motorcraft 2100 2bbl carb. It's cheap, easy to do, and improves both idle and power.

Re: Carb ???

I had nothing but trouble with the Weber that I put on my 89 YJ 258. Called Weber many times and even sent the carb back to them when the butterfly valve got stuck in the closed position. They told me that all they did was give the flap a good rap with a hammer. (I could have done that.)

The bottom line is that Weber treated me bad and I ended up with $275 worth of scrap metal. I know that others on this BBS love the things but I will never buy another Weber product again just because of the way they treated me. Also, on the box that the carb comes in it says in big letters "No Warranty Whatsoever". From my experience, they mean it.

Good Luck!

Re: Carb ???

I appreciate the candor, I went through the same thing with ARB on their old style compressor. Anybody out there running the Holley 390 cfm or the Pro Jection?

Re: Carb ???

I had a Offenhauser Dual Port intake and a Holley 390 cfm 4 bbl. carb on my 225 V-6 when I bought the vehicle. After getting it set up correctly, it seemed like a capable carb. I never took the vehicle off-road with that engine. Have since replaced the 225 with a 252 V-6 with Edelbrock Performer intake and Edelbrock Q-Jet carb and it is the best there is for off-road, for a carb. Another choice would be the 500 cfm Carter AFB which is less messy to dial in the jetting. Both the Holley and Carter will require the addition of spring-loaded needle and seats for off-road. Edelbrock Performer carbs are clones of the Carter AFB's. My tune-up guru says the quality control is much better with the Carter's.

Re: Carb ???

I have a 1980 CJ 258. I replaced the stock carburetor with the Holley 350 cfm, 2 barrell. I had done the TR upgrade, including MSD 6A earlier, liked the results and so then I wanted to try to help mileage since it was mostly terrible. As you note there are lots of opinions here regarding Holley but I had one on an earlier 304 and was quite happy with it. So I ordered a Holley, model 2300 from Summit Racing part# HLY-0-7448 $235.95. In addition I ordered an adaptor plate so that it fit the intake manifold, (can't find the part # but the guy at Summit figured it out for me.) I liked the result immediately. Smooth idle, responsive and best of all much improved fuel mileage. On one of our trips a couple of guys following noticed black smoke under acceleration so when we got home I changed the stock jets (#61's), with smaller jets #59's - a $6.00 investment. Black smoke is gone. I have had no problems what so ever with the carb in off camber/bouncy situations. Hope this helps. John
