Carburetor for 1978 CJ7 304 stock intake

I have finally decided to come back to the land of Jeep after a long hiatus. I will be trading my current vehicle, which I will not mention since this is a Jeep forum, for a 1978 CJ7 with a 304, th400, quadra-trac. The 304 has stock amc intake on it but the carb is a 2 barrel holley which will not remain functioning, it's tired and needs a rebuild or replacement.

I realize that I can put on a motocraft 2100 2 barrel as that is a direct fit for year and motor, however I have some questions. For a 1978 with a 304 was it electric or manual choke? The owner of the Jeep told me there are not any electrical wires going to carb which makes me believe it is not an electric choke, but I have not had to mess with carbs ever as any vehicle I have had never had issues with the installed carbs so i never bothered to learn a thing about them.

I simply want to put in the right carb since I am ordering online and would like to be able to bolt to factory intake using the stock lines. The owner of the jeep was not able to find any numbers that were helpful in identifying the specific holley 2 barrel currently on it.

I seem to find a lot of motocraft 2100 carbs at various prices but am not sure if there are variants of the 2100 for the Jeep and what I need to look for. My price range is 200 max including core, which I realize puts me into the rebuilt/used category but I only need this to get the Jeep up and running so I can drive it until next summer during which an engine swap will be taking place.
