mc2100 carb

i have a 4.2 carter carb im thinking of going to a mc2100
what do u think would be the best donor car to get a carb off of? what year? model?
and where can i order the adapter plate that i keep hearing about? thanks

Summit Racing sells the adapter plate.
Or Cdn Tire if your in Canada.

And the best engine to get it off... if your ordering it and need to know what to tell them, then it's an AMC 360 From a 86 or so CJ.. I think that's what I asked for. But make sure it's the MC2100.

If your just going to a yard to get it, then it doesn't really matter what it comes off.

The 360 was never used in the CJ. 81 was the last year a 304 was used in a CJ.

And I *think* it's also an issue to use a 2100 other than the 1.08 venturi size on a I-6...

Here's a decent write-up on the process

I stand corrected then..

Get the one that went on the V8

Venturi Size is 1.08
And Jet #47


This is the one thing that the 2100 write up doesn't say very well. It just says find a 2100, but I had a hell of a time figuring out which was the BEST one I could get seeing as how I was just buying one flat out from the parts store and they were all the same price so I may as wel had got the best one.

does anyone know what year and model i can get the carb off of? mc211, 1.08 venturi and 47 jets? im going to the wrecking yard and going to rebuild the carb but i need some idea od what kinda car im looking at
thanks

Go after a Ford w/ an inline six (I can't remember, was it a 302?). The rebuild kit is cheaper for those 2100's. They were used until about 85 or so I think.
I don't know anything about the jet size though.
I bought an adaptor off the shelf at Advanced Auto to $17

ok i need some help here
all the wrecking yards i have called NEED to know the year and vehicle the mc2100 1.08 venturi came out of so if anyone here knows this please email me back or post back
also was told that the inline 6 was only a 1 barrel
again if you know what year and model to get the mc2100 1.08 venturi out of please help

Hunh.

It came out of any Jeep 360 throught a year range, say like 72 -> 85 or so?

My buddies FSJ has the 360 and a MC2100.


This is what i hate about yards and shopsthat dont realyl know whats going on.

You could say... (just picking a year here) a 1978 Jeep CJ5 with a 360.

But then if they have the 1979 with the MC2100, they won't even look, they'll look only at the 78s and say.. "nope."

I don't remember the exact year I gave.
I just told the parts store guy (napa was really helpfull) that it was for a 1972 CJ5 with 360.
He said, ok I can get one of those for you. I asked if it was the MC2100, he said no, so I said it was a 1973 CJ5 with a 360... and so on.

Then just double check the Jets and Venturi..

If I were you, head to your favorite parts store, because they have computers, and figure out what you need. Then head to the yard with ALL the information.
