I am going to hook up an Autolite 4100 4V carburetor to my 1985 Ford F150. This carburetor uses a "hot air" choke instead of an electric choke, which I understand is actually better. However, I am not sure how to install the "hot air" and the "fresh air" tubes.

There is a "hot air" tube that goes from the choke down to the manifold someplace and then another "fresh air" tube that supposed to hook up under the carb plate somehow, but then I do not know where the other end goes.

The next thing is I am now running long tube headers, and they do not have the "stove" needed to hook the "hot air" tube to. Is there another way to make this "hot air" choke work with headers?

Any help would be appreciated!

 

Not really sure what your asking pictures may help a little.

 

There used to be a Choke Stove kit available in the HELP section of many parts stores. It was a metal chamber that clamped to the header/Exhaust manifold. There was tubing to run from the stove to the carb and a woven insulating sleeve. If not in stock, the parts store may be able to order it if the kit is still made. It should be. There is no fresh air intake line on this setup, but I don't think your 4100 will have the fitting for it anyway.

Personally, I would put an electric choke thermostat on it, run a wire from the "S" terminal on the alternator, tweak the adjustment as needed and call it done. The electric is a bit less finicky.

 

I have always had good luck with the electric choke so if your willing to go that way that is the best in my opinion.
