Now that its getting cold out, my car is getting harder and harder to start in the morning. I have sidedrafts on an early 71 car and there is no choke hooked up. This wasn't a problem in the summer. The car has a choke knob but the cable has been cut off.

What is the best choke option for these cars? Get a new cabel and hook up the manual choke? Is there some other type of choke that would make the process automatic? Thanks!
