Motorcraft 2100

I am in the process of ditching the Holley 2bbl that was on my Jeep from the PO and installing a rebuilt 2100.. Can anyone who has this carb on their 304 post a few pix of where all the vac hoses's go and throttle linkage is set up?? Aslo the fitting on the choke?Thanx...

 

I would be happy to, but mine was stripped of all the vacuum plumbing by PO #1 or #2.

Throttle linkage might be here: http://www.nmr.mgh.harvard.edu/~reese/ResizedJeepIPics/

Try #848

 

Here are a couple of pics of the choke.

In the second picture you can see the vacuum line just behind the flange nut. This line goes to the distributor.

 

^Thanx. That helped a bunch. The only fitting I did not see was on the choke. The choke on my new carb has a threaded fitting . Any idea?

Also on teh throttle side there is a linkage affair that I have no idea what it does.. It is on the firewall side of the throttle linkage and has a screw adjuster of some sort..

 

Auto trans downshift linkage? Remans will fit a lot of different applications.

 

The carb shown in the pix you referenced must be a different version than mine. The part in question is noted with the white arrow. Also mine does not have the parts noted by the blue and red arrows. Otherwise the same pretty much.
AARGGH!! Upload probs, I'll try in a new reply. pic below

 

Picture?

 

Pic now maybe? Nope, the server aint likin what I am doin.. Gettin an error. But the pix you posted are exactly what i need. Just need the throttle side to verify the one part i do not understand.

Edit:The carb shown in the pix you referenced must be a different version than mine. The part in question is noted with the white arrow. Also mine does not have the parts noted by the blue and red arrows. Otherwise the same pretty much.

 

Ok I pretty much understand now. Looks like a trip to the local wrecking yard to find a few missing pieces..

One more question. The metal tubes shown in the second pic: Are they lines vac lines going into the manifold? Or heat lines? My engine has the piece the lines go into but no lines. Just holes, and they look like they just go into a deadhead in the manifold. Also what is the hat looking piece in the line to the choke?

Thanx guys.

 

The blue arrow points to the carburetor dashpot. It keeps the throttle from closing too quickly. The red arrow is the choke pull-off. It opens the choke plate some at high vacuum (that's what it is called, but I'm inferring how it works). White arrow is the auto trans kick-down lever (not used).

The metal tubes connect to the choke stove in the manifold. Draws heated air into the choke cover to help open the choke plate. The connection to the air horn is a source of filtered air. The gadget in the middle of the tube that goes to the choke housing is a delay valve of some kind... don't know any more about it - surprised that a '75 has one.

 

So do I need a dashpot? My choke linkage is on the far side where the choke stuff is so I am ok with that. . The carb shown may be the 2150. So the air to the choke cover comes from inside the carb air intake (filtered) and goes to the choke via the plate deal (choke stove) in the manifold?

 

The dashpot is a real good addition if you can find one. Without it, the engine will tend to stumble, possibly even die, when you back off the throttle quickly. You can increase the throttle speed to compensate, but that causes other headaches.

As for choke routing, you are correct. Vacuum inside the choke housing pulls air from inside the filter, through the choke stove, and into the choke spring housing. The choke stove sits inside the exhaust crossover in the intake. Make sure the tube in the choke stove isn't corroded and full of holes or you'll end up pulling exhaust gas into your choke housing. Bad situation.

 

Thanx again. I found a new dash pot at a web store, I'llorder one today.. I am missing the mount so I guess I'll be searchin the junk yard today for that as well as a choke stove w/the tubes still attached..

So far so good. I believe I have found most of the parts I will need on the web. If someone could post a close up of the bracket for the dash pot I'd be about set. I am thinkin I will probly fabricate the bracket if I can understand how everything fits and works..

 

Ok if anyone is interested I found a new dashpot and a new set of thermal chke tubes. Took some surfin but they are there..

dashpot was here:http://www.rockauto.com/dbphp/mak,JEEP,1972

Thermal tubes were found here: http://www.rightstuffdetailing.com/parts_catalog.htm

 

Here are a few pictures of my dashpot and bracket, hope it helps, just successfully rebuilt my 2100, started 2nd kick!, i have a step by step photo gallery if you need it. Too big to post.

 

Thanx for the pic. I now have all the needed parts on the way.. I even found the mount bracket for the dashpot. Pony Carbs in Las Cruces New Mexico had everything, including the thermal choke risers. Unfortunatly for me I contacted them last.. So I now have parts coming from 3 different places! If anyone needs 2100 parts I can point ya to the right place.

I also recieved a reply from the carb guy and he says the dash pot is not necessary.

Thanx to all who took the time to reply.
