Allow me to add to this with some pictures.
Of the carb choices out there for you, when you drive the street, weather it's once in awhile or everyday, you'll want an elcetric choke. I see them coming in different configurations. The first one being a housing, allway black in color and round on the passenger side of the carb. Picture #2.
All you need to do is add a single wire from a 12 volt source thats "ON" when the key is also in the "ON" position and off when the key is off.
The other way it's done is in combo with a bi-metal spring, in MoPars case, inside a well cast into the manifold. A electric assist is added sometimes. You can see it alittle in the overhead shot, picture #1.
The choke well spring has a arm that comes up and mounts to the carb, right where the linkage from the choke pull off meets the piviot point. Where the choke plates rod runs through the body to the "Outside" of the carb.
A full manual choke carb has a cable where you regulate the opening.
There is no performance gain in a manual choke carb. Your saving a few bucks in trade for ease of operation.
