Motorcraft 2100 Carb

Question, Can I convert my Motorcraft 2100 Carb with no emissions into one with emissions. And please provide me with the how information on how i would even do that.

Or you do you know a place I could buy a reman Motor 2100 Carb with emissions or other carb that would trade a core without emissions.

Thanks for the help guys.

I am sure more knowledgeable people will chime in but in the meantime, I converted my old carb that had everything off of it except the pcv and the vac advance and it runs just fine on the 2100.

Check ebay. There is a guy on there that just sells MC2100 carbs for jeeps. I think the emission carb you want is the MC2150. Is there a reason you want the emission system hooked back up?

No reason other than the jeep smells better and and I have the complete vacuum system other than the correct carb.

Is there something I can do for the time being like the basic hook ups until I get the right carb?

Not very hard. Do you have it mounted on the intake already?

Well I am trying to go from memory because it has be awhile since I did this and I am not in front of mine. There is a port facing the front of the jeep at the bottom of the carb plug that. There is the vacuum advance that goes to the distributor should be on the valve cover side that must be connected. Then I believe in the back of the carb there should be a hose that goes to the PCV must have that. I believe there might be one more that goes tot he air cleaner not important but plug in if there.

Beyond that I believe it is it, just plug all others but make sure that they have no leaks.

I can look later but not there now.

If I were you, I'd purchase this carb., for $180.

I can't say enough about National Carburetors. Their reman'd carbs look absolutely new, are setup to your specific application, are dyno tested, and come with a good warranty. Their customer service is also top notch.

I'm leery of the "Ebay Guy" for several reasons:

1. He advertises his carbs as new, which I don't believe they are.
2. I've heard his customer service is lacking.
3. I'm quite sure his carbs aren't dyno-tested and I'm not sure about his warranty.
4. His instructions promote scrapping the factory air cleaner in lieu of the shiny, but less functional, open breather in his kit.
5. His explanation of ported versus manifold vacuum advance shows a clear misunderstanding of the subject.

I thought we went thru this the other day?

The carb you have is a NON-SMOG carb. From the pics you posted, it is lacking a ported vacuum port to run your EGR/CTO and your canister/CTO. If I recall correctly, it also doesn't have the large manifold port for the PCV in the rear of the carb.

If you want all of your original vacuum systems hooked up correctly, you will need a different carb.

Good deal.

FYI, if you want to hook your climate choke back up, you will need this carb. It's even a little cheaper, but you will have to purchase new choke connector tubes, since yours are either missing or snapped off.

Since your engine appears to have had the climate choke, you may need to wire power to the e-choke version that I linked to earlier.

Clear as mud?

I think I posted the correct vacuum diagram on your other thread. No?

Been having problems with my MC2150 from the eBay guy. Less than a year old, and only about 500 miles on it.

This place is local to me, and if I had known about them before I bought from eBay...I'd have gone here first.

Mine is being dropped off there tomorrow morning after I get off duty.
