Yeah, and it's always the carb that's at fault. If it's a Holley, someone will say, "Replace that piece of junk with an Edelbrock," and vice versa. North Texas isn't exactly like the upper Midwest in the winter, but I've never had issues starting my old cars or trucks in sub-freezing weather, and waiting no more than 30 seconds before driving. And that's with several engines and carb combos. It's mainly a matter of choke settings, including fast idle.
I did have a "hesitation" issue on a 350 engine with a 600 Holley on a day in the high 20s. It was so cold, the coolant wouldn't get above 160F or so even after 15-20 minutes of driving! But I tuned it out with slightly larger squirters and 1-step richer power valve.
I actually enjoy playing with carbs. My all-time favorite is a old-skool 650 Holley #80783C. Classic gold finish and worked great at all throttle positions and loads, with zero changes from stock except for float level and idle mixture adjustments. Sold a car with that carb installed. Wish I would have replaced it first.
