I am pretty new to this. I am working on my 66 mustang (289 2v) and I have a pretty stupid question. What kind of choke is on there?And could you tell me how I can tell?

Thanks
Dom

 

If you still have the original exhaust manifolds you will have a stove and two tubes running from the back of it up to the carb. The choke gets heat from the manifold and in the round black thing there is a spring that opens as it gets hotter. That spring is attached to the butterfly on the carb which opens as the engine gets hotter. Here are some pics of what it should look like. If you have aftermarket headers, then there is a stove set-up you can get. Let us know.

Thanks!! I found it. If i changed the headers would I have to go to an electric choke?

 

Maybe this doesn't apply to your car, but when I first bought mine long long ago, the choke was heated by one of the heater hoses held next to the round black cover by a bracket. It was never hooked up to the exhaust manifold. It's easy enough though to convert to an electric choke. You just need a 12 volt source that's only hot when the engine is running, which is normally the output of the alternator I think.

 

If you look at the first picture carefully you will see the bracket for the heater hose that is next to the black choke housing. If you put on headers you can either go electric, manual, or use this choke stove set-up.

The clamp on stove will work, but it will heat up and cool off faster than iron manifolds. Be sure you leave the heater hose against the cover, it serves as a moderator for the choke thermostat to slow it's response in both directions.
