4-bbl Carburetor "choke" question(s)

[travisdavid1987]

   So I am away from my truck till next week, because we are in the process of moving to NC from GA. I figured I would go ahead and explain this situation I am having now with this carburetor and see what you all think about it.
   When I first got this truck the carburetor on the engine has all the components that it needs except the item that is supposed to regulate the coke. I am new to messing with carburetors so I firstly need to know what part I need to buy to get this carburetor's choke to work on it's own.
   Secondly, after the motor has warmed up and is running... the choke plate should be open correct? Well the thing with this is that after the truck is warmed up I press the choke open all the way, I jerry rigged the choke plate with a pen spring for the time being, and the truck stalls. What would cause that to happen as far as the stalling goes as well.
   Thanks for the help and any advice you can give me. I will put up pictures of it after I move and get settled in up in NC.

Picture would help greatly. Assuming you have an electric choke look for pictures of a similar choke assembly together to get an idea of whats needed. If it's not electric (hot air) I would get a conversion kit to make it electric. you will also need to find a 12v with the key on power wire or make one to hook up to it. Also when you post a questions; give as many details as possible ie; model year, engine, carb type/brand, modifications etc.

I will I am just away from the truck at the moment and will not be back with it till Monday sometime. So I was just giving a broad description of the problems to see what people think at this moment.

Ok so I have more information on the carb and a few more questions and pictures. It is a Carter AFB 4bbl Carburetor, serialed: 9605S 3335, year made is sometime between 1962-1965. I couldn't find much information on these or get a manual for them downloaded without paying for it. So I figured it'd be better to ask you guys before I spend money on looking up information on this if its better off for me just to put money into an Edelbrock carburetor. Especially since I cannot seem to find and electric choke for this carburetor anywhere. Im pretty sure it's the original carb that came with this motor though, since I did find that the Chevy 327 motors from 1962 to 1965 came with the Carter AFB Carb so thats kinda cool. 1980c10, other than the information I just prvided the only modification I have done right now is a pen spring where the manual choke should be, just so that it will idol somewhat decently. Here are a few pictures, please pick away at it all ideas and information are much appreciated!

From the little I know of carbs; it appears to be a "divorced hot air" choke. Depending on your goals for this truck etc; I would upgrade to a better carb with an electric choke. This carb can not be converted as far as I know. Also, If you ever go with another intake manifold you will not be able to operate this choke if the intake is not set up for that particular choke.

The Carburetor that you have is called a "Carter AFB" these Carburetor's are not made anymore.  You can use any parts made for the "Edelbrock Performer" series Carb's...  They do make an electric choke conversion,  Made by Edelbrock that will fit right on the Carburetor that you have.

If you wanted to run a stock Carburetor for the intake manifold that you have, the choke is controlled by a Bi-metal spring that bolts down to the intake manifold,  it is controlled by heat from exhaust that flows through the exhaust crossover portion of the intake.

I believe this part would work if this choke had the bimetal spring located on the carb with the heat riser tubes; however I don't believe it will work given this chokes spring is located on the manifold and uses a mechanical linkage to the choke from there.

I may be wrong in this, but this is my undertanding and I don't belive there is a kit made to convert this to electric if this is the case..

[Camfirchev]

The conversion kit listed in the link is an electric choke,  Just tie the red wire from the choke, to the large pink wire going to the ignition coil,  The other "Black" wire from the choke, I just ground it to the carb itself.  I have never seen anyone try to use the Bi-metal choke spring from the intake to the choke lever on these carbs??  I would imagine it could be done, but all the Engines that I have seen using that choke set up use the Q-jet Carburetors.

Awesome thanks to everyone for your replies that is definitely going to be a HUGE help when I get around to working on it. I will keep everyone posted here soon I am going to start taking it apart and actually looking at everything that I got going on with it. thanks again!
