Too cold to start car

You're not doing your car, and particularly your engine, any good by running and driving it with a carb that isn't working properly. If you don't have the tools or know-how to fix your carburetor, then I would suggest go and buy a new one with an electric choke and slap it on. Right outta the box is probably going to be a 400% improvement and you will wonder why you waited so long to do it! That's the best friendly advise I can give ya. Call Holley and give them your engine specs, as much as you can, as well as other info about your car's weight and gears and they will tell ya which one is best for your car.
I recently did the same for my '78 Dodge Van and it was some of the best money I spent.
