Help identifying this intake manifold part?

On a '74 CJ5, 304. Connected to a 2100 carb. Trying to see if I can find a replacement part for it.



Many Thanks!

 

I wanna say its the choke stove.

There is some internal suction under the black cap that draws hot air out of it to open the choke faster

 

Jeep calls them "choke heater tubes" aka a choke stove. I doubt there's any source for a new parts - you may be able to find a good used take-off if this one is broken.

Is it broken? It looks intact from the picture. I'd just clean it and use it - or leave it in place. You can buy the gasket that's between the plate and the manifold easily.

Yes, there is vacuum under the choke cover. There is an internal passage in the carburetor that connects from there to manifold vacuum. The vacuum draws filtered air from the air horn, through the tube in the pocket in the manifold, and into the choke cover. There is an exhaust gas passage to the pocket in the intake manifold.

 

napa used to have a manual conversion that went on instead of that one it had a hole for the linkage to go through in the middle...

 

x2, Im a fan of mechanical, cable linkage. No surprises, and not hard to retrofit.

 

As time goes on the inside of the exhaust manifold will get a GOOD coating of black stuff, (I not using the "o" word, but an old jeep uses it), and carbon against the wall and will reduce and finally stop the transfer of heat.
On quite a few cross over tubes on V-8s, I've had to use a chilsel to create a path for the exhaust to travel to heat the carb and stove for the choke.
Run the jeep for a few, feel the area, if it's HOT, you still can use the stove.
I've turned the spring on the choke, (reduce the spring tension) to make a "sick stove" work.
I've made some up using copper tubing, a LOT of solder, silicone.
But in the end the "ol standby" is the manual cable.
Nothin' better than "forcing" the motor to run with the choke open before it's warm, sputtering stumbling up the street!

Jeep- that's indian for, "sure that's the way it SUPPOSED to be, but it can me modifed"

 

Go with the manual cable, you can make much better choke adjustments than a metal coil. These things are finicky and once they are adjusted right they don't stay right very long.
