Carburetor

Looking to buy a new carburtor. It will be used for some off road but mainly just for the street. Whats the best one money can buy for an 84 cj 7 with the 258.

Depends on what you have done to your engine.
If you still have the 'Computer' then you will need to replace the Carter BBD you have with another Carter BBD.

If you have eliminated that stuff, then your best bet would be a MC 2100.
---------------------------

I don't like Webber carbs, but that is a personal opioion.

In my estimation, the 'BEST MONEY CAN BUY' is fuel injection...
Other than that, a Holley with the proper 'Off Road' upgrades.
Easy stuff, but most people don't take the time.

The most cost effective/'bang for your buck' will be the Motorcraft 2100.

I willl throw my vote behind the Motorcraft MC2100/2150.
They are Just as reliable, easy to tune, performance is great, much cheaper, deeper knowledge base, been around for 40+ years, easily found in junk yards and rebuildable in 2 hrs.
The list of advantages goes on with not one down side that I have encountered.

I dont know any thing about rebuilding carburetors. Can you buy one new or remanufactured and what kind of mods do you have to do to get it to work on the 258.

Check out this link to a fellow who sells them on ebay. He also provides the linkage that you will need. I've never bought from him, but I've heard some others talking about him in another thread. They seemed to be very satisfied with his rebuilds. HTH http://cgi.ebay.com/ebaymotors/Motor...QQcmdZViewItem

I bought one from him. Hooked up with minimal issues and fired right up. I've been very happy.

A kit for the BBD carb runs less than $20.00 most places and is really easy to put in. That carb is supposed to get a kit every time the engine needs sparkplugs and gets really cranky about it when it is not done.

Mine just purrs, so do all the ones I have helped folks kit. The kit instructions are straight forward, you just don't unscrew or unadjust anything you don't need to to clean it.

As far as aftermarket carbs go, none of them seem to be set up for the 258 because none of them can pass emissions from what I have read over the years. The BBD, even with no computer running it will tune up easy and pass the sniffer.

Take the 2100, great carb, but made for 304 cubic inches, not 258, so it's too rich so the gas mileage is lower and the sniffer says fail. The BBD can get over 20 mpg highway easy, it's 'supposed' to from new, I get 22 mpg if I stay under 65 mph and my CJ friends fill up real close to mine when we are on trips, so theirs are the same. We beatYJ and TJ 4.0 guys by at least $15.00 a fill less.
