I live in northern IL and I drive my stuff year around. Since I know how to properly set up automatic chokes, every carbed car I've ever owned, and drove on the streets, had a properly adjusted automatic choke. When they are properly set up, the motors run correctly from stone cold (-30 F) to dully hot (+90F). I can not understand how people can stand a poorly running car at any temp. Maintaining proper automatic chokes is just like maintaining anything else on a car. There are things you have do to keep functioning, but once set up, maintaining an automatic choke isn't any more difficult then maintaining any other part of a car.

Even my street drive high performance cars had operating automatic chokes. Our dirt track cars did not have a choke, but once those started up, it was past the need of a choke.
