pop quiz - Carb question

I would like to know what type of carb is in my jeep. My dad said a mechanic switched out the carb many years ago and I would like to know what you experts think it is. Thanks for all help!

Sure looks like a Carter BBD, which was OEM on 258's.

I agree with Tim, appears to be a stock Carter BBD.

Re: pop quiz - Carb question

were all cj7 carters non-computer controlled? I don't see a stepper motor or the solenoid on the throttle linkage (is that hooked into the computer anyway?)

Re: pop quiz - Carb question

The float bowl vent looks like it is a computer controled version of the infamous BBD. The 'kicker' that mounts to the top of the carb and pushes on the very front of the linkage seems to be missing though. The stepper motor is a big thing with a ton of wires on it sticking straight out the back of the carb...about the size of a D cell battery, maybe a bit longer. What year is your CJ?

Re: pop quiz - Carb question

Re: pop quiz - Carb question

Sounds like it's performing perfectly to factory specifications [img]images/graemlins/grin.gif[/img].

Options include rebuilding the Carter, or replacing it with a Weber, Rochester, Motorcraft 2100 or fuel injection. You should find lots of info on all these options here by doing a search. Some of the carb replacements are a direct bolt on (like the Weber) and others require an adapter (Motorcraft). Cost will range from junkyard rebuild of Motorcraft to a new Weber ($350??).

Re: pop quiz - Carb question

Jeff,
It depends on what state you live in. If your state does visual smog checks (in addition to the tail pipe), then you need to keep the BBD. Otherwise, your wide open. The Motocraft or Weber seem to be the most popular. Or you can save yourself a lot of trouble and go fuel injection.
