Dimensions for bottom of Carb

[odiekokee]

ok. what's the cylinder with the plug coming out of the lower section between 2 vacuum lines? and the book shows some kinda vacuum dashpot looking thing on the black bracket thing attached to the high throttle butterfly. that I don't have either. what is it, do i need it, and where do i get it?

I defer to drddan or someone else with a carbed car....

Ok, new plates that fit are in progress. I need to talk to whoever has done this conversion before.

Sorry I missed the recent continuation of this thread. I have put up my Festiva for winter and driving my 4wd Ranger again. So havent been checking Festie forum.

Is this the Escort carb from the stovebolt.com site or did you get one off ebay or someplace? If its one off stovebolt site then its non computer carb and the extra wire is most likely a solenoid to cut fuel off when you turn off ignition. It was very common on Japanese carbs and Ford may have used same setup. Basically just connect it to ignition so its open when ignition is on and closed when ignition is off. It allowed them to very lean running carb without runon issues. During 70s many manufacturers ran lean carb and played with distributor to meet emissions. May have met emissions but created lot other side issues. Runon was one of them. The Japanese solved this with this solenoid and it worked quite well.

As to the plates sorry it didnt work out, at least posting here keeps anybody else from going this route. As I said, I had no personal experience with these plates, that they just looked right. I made my own plates out of 1/4 inch steel plate. I still think its odd that the Festie side plate was same shape and same offset for bolt holes but just not quite exact match. That is just weird they'd go to trouble to make such a miniscule change when they went to feedback carbs. I am wondering if gasket is whats bit off and when you actually remove the current carb, you will find they do fit the manifold.

As to Escort carb base, since I dont have one, I just couldnt say. Again since its based on Weber design odd they changed base plate mounting holes. I know the old Holley-Weber carbs used on Pintos and Vegas did use the Weber bolt pattern. The Carter-Weber carbs on Fiesta and Escort, I just figured probably same but didnt know.

And try contacting Festy46 as he has lot experience with the escort carbs. He didnt use adapter plate but modified the actual manifold or machinist friend of his did. Unfortunately not all of us have a bored machinist friend close by that will do these little one off projects for free. I suspect if you could just get somebody to tig weld some additional aluminum to manifold, you could then drill and tap own holes. There are times I'd love to be set up to do tig welding but just not often enough to justify buying the equipment.

As to choke, look in Escort manual how they hook up, think it was just 12V hookup as TominMo suggested. I personally dont like electric chokes. I have a hot water choke on the weber in my Festiva. I prefer hot water choke. But would even do manual choke before I did electric. The car manufacturers went to electric choke cause first its cheap and simple. Second it opens choke quicker than water choke to please the EPA. Unfortunately this can also make engine stumble if it opens too soon. The older Amercian hot air chokes worked fine if you did bit maintenence and checked for rusted heat tube. But carb had to be designed for it as there is a small vacuum passage cast into the side of carb to draw in the heat. I have a Ford 300 straight six in both my Ranger and my F250, both with hot air choke and pretty simple and reliable. Manual choke not bad, but seems to be incomprehensible to any person not familiar with them who tries to drive the car. Its like trying to explain manual transmission to anybody who has never used one. Doesnt help that lot of manual choke kits are made super cheap and dont work all that well due to cheapo cable.

This is guess on the fuel shut off. You really need to post a picture for more accurate answer. Car makers attatched various little gizmos over the years to meet emission requirements. If its internal fuel shut off valve (screws into the carb) then you need to connect it and it is a beneficial thing. If its just some gizmo connected to throttle linkage, maybe to prevent throttle closing too quickly, dont worry about it, can even remove it probably. If its an electronic gizmo (throttle positioning sensor) directly on end of throttle shaft then you have a feedback carb and it isnt going to work in a non-original application.

Ok, this is curious. Going to that stovebolt site that sells both new Carter-Webers and rebuilt Holly-Webers, they sell an adapter to put these on old one barrel manifold. This adapter is said to work with either the C-W or the H-W. Look at the carb gasket. It is the SAME for both! So I think the Carter-Weber does use the Weber bolt pattern cause I know absolutely that the Holley-Weber does. And it looks just like the base gasket I used with my Weber.

^ That is a great find! Lotsa Festy peeps who want to switch to H-W or Weber will thank you for this. And only $15!!!

Look again. this adapter is meant to mount a C-W, H-W, or Weber to a single barrel manifold. This stovebolt guy sells these C-W and H-W to use in multicarb setup on old American straight six engines that originally come with a one bbl carb. Smaller straight six can even get away with a single H-W, the C-W is too small and only usable in multi carb setup.

I only posted pic to show that it seems the C-W and H-W and by extension the Weber all have same base mount pattern as they only include one carb base gasket with the adapter. So I am confused why the C-W of original poster doesnt work with top plate of adapter he bought. Did he try the actual C-W carb with the upper plate or just a gasket sold to him as base gasket for the C-W on the Escort?

Well, here are pictures: Everything looks pretty much the same. The thing with the wire is in the first picture, where bonanza's picture shows a plug?

I don't really know what the blue plug covers in the second picture. And i don't know which way the throttle is supposed to work or exactly how to go about that...

Also including both sides of the throttle linkage doodads.

[odiekokee]

need to know what the thing in the center of this picture is, with the wire coming off.

Besides that, I think i may be almost ready to start thinking about doing something like planning to think about starting to swap it.
