I don't understand what you mean when you say the car didn't want to turn on.
Could you describe the problem in more detail?
Does the engine crank over with the starter?
Does it cough and sputter after the starter stops?
Can you get it running at all by moving the throttle?
Any history or other symptons you can describe?

Yeah Bubba, that's a tough one to diagnose!!!! My first off the wall, non informed guess would be that the temp dropped and the choke is too tight. But, I could be way off base. We will have to wait for more info.

It is very hard to tell whether the problem is fuel related or an electrical problem without knowing more details. But having problems this time of year would make sense that the choke is acting up.
Going to need to know more....

Sounds like the choke pull-down might need adjustment.
You can test the choke pull-down by applying a vacuum to see if the diaphragm holds vacuum. If it leaks, replace it.
You should adjust it to open the choke plate about 1/10" to 1/8" when vacuum is applied. The pull-down adjustment screw is on the back of the diaphragm chamber (2150 carbs) or on the bottom of the diaphragm chamber (2100 carbs).
