New carb tomorrow!

Hey all,

Installing my new motorcraft 2150 carb tomorrow and just curious, what would you also recommend replacing/fixing while I have carb off? Gaskets? Electrical stuff? I'm looking for suggestions so anyone's two cents is appreciated! Also installing new brown dog motor mounts!

Thank you!!!

i would remove all the extra junk form the engine bay. those little valves hanging off the firewall, redo the vacuum lines, check the wiring for the starter and alternator to make sure the connections are tight

Yeah, all the extra junk hanging around the engine compartment really is there for the Carter carb and its now useless. Do the Nutter bypass and you can even remove the ECU and associated wiring. Your YJ has a lot of doubled up sensors, one for the ECU and the other for gauges. I did mine and I had two shopping bags full of useless crap, one vacuum and solenoids, the other full of sensors and wiring I pulled from the loom.

So I can remove a lot of those vacuum lines and it won't affect the performance or make me not pass smog? I'm in California (unfortunately) so is the nutter bypass compliant with California smog?

Thanks again for the advice!

No, the Nutter isn't compliant with California smog rules.

From what I hear, any change to the carb is not in compliance with California smog.

You will have a hard time getting to run right unless you do the Nutter. The computer controlled stock carb is a part of the whole system. Once you take that away, the computer will be trying to regulate the carb but won't be able to because it isn't there anymore.

You really need to rethink your plan.

Hmmm. So I bought the carb from the Colorado guy on eBay and through talking with him, he said the visual aspect is the only thing that people have had issues with as far as smog in CA. So he gave me instructions on how to modify the existing air box so it covers the new carb to pass inspection. BS, I know.

Did I get scammed?

Well, if they don't figure out what you did, then maybe you'll be okay.

I'll let people from California answer further on what you can get away with.
