After two years of tuning during the Spring and Summer with O2 sensors, I found that once the cold Fall air hit I started having lean cold-startup problems. Since I had leaned out the carb to idle/transition/cruise in the 14.0 range, I found that I had to richen up the electric choke to compensate for the colder air with the leaner A/F setup. I am now an electric choke fan.
I do remember that I used to run a non choke DP Street Demon on the same engine. That carb would fire right up and idle on it's own in the Fall temps with two pumps of the pedal. I now wonder how rich that carb was running at idle/transition/cruise to be able to do this.

Neither would I. A choke on a street car is a must, especially in a cold climate like where I live. And it's a safety feature. I can just imagine an emergency where someone has to drive me somewhere, and they can't even get the car running. That'd be my luck.

A well-type choke can be disabled by taking the clip off. a classic electric-only choke can be taken off with a screw driver. I don't think I'd be caught dead driving around in an old car without a toolbox
You're saying having to plug in block heaters is more convenient than keeping a choke tower and utilizing it? and if you happen to drive somewhere and leave it sit for a few hours? I just can't see it

I’ve been considering no choke………. I used to have a manual choke but it was a bit hit and miss, and also I never quite trusted that it was not fully open (and staying open) even after the engine was warm. No biggie I could have tested for sure. Electric chokes kind of take away your control – if something goes wrong with them you can’t start the car – cold or hot. How likely is that to happen? Very unlikely I guess but I did have a bad experience decades ago with my daily driver. However running no choke is not a no brainer either. First I’d like to be able to start and drive away quickly on the odd occasion I would leave early in the morning in my Challenger – to keep the peace with the neighbours! And presumably if you get it wrong you can flood the carb etc (can also do this on a manual choke).
For these reasons I got to thinking about a couple of block heaters instead. Most of the time would not need but for that occasional early start in very cold weather it would achieve the aim and your engine and cylinders would thank you for it too.
Maybe overkill but just another option…..
A choke is nothing to be afraid of, expecially a manual choke. You can bolt a small piece of wire on manual choke carb to keep it from coming on like I did forever. Then it was real easy to bolt a cheap metal choke cable in place of the wire I bolted in.
That's all there is to it. No tricks or secrets and helps a ton at start up, then turn it off after it starts(push the cable in)
It's not something someone should stress over ...lol
FWIW I would not run a race carb on the street now thAT i REALLY DRIVE MY CARS.
A finely tuned muscle car on thee street impresses me way more than brut horsepower, on the street.
I'm becoming a dinosaur as it seems less and less people know how to tune a old car, or any car for that matter.

My Holley 750, and Quick fuel 950 have no chokes. Been running my Duster with out a choke for almost as long as I've had it. But out here in Calif., it's not needed much. Besides, the choke horn just slowes down the air flow. Need plenty of flow for .
Same here in So. Cal. Doesn't get used much even if I had it.

On a street driven car what's the disadvantage of having a choke?
None that can think of other than missing a couple horsepower at 6000 grand rpm or higher.

Facts as I know them DP Holleys don't need a choke period hot or cold I can start my car after sitting for weeks in cold with couple jabs of the gas.Even down to 5 degrees TQ's will not start without a choke without a fit if at all AVS will start provided the squirters are drilled Q jets wiil have fit but start with no choke with backfiring and all.
If I have a holley I remove the choke and I have two electric setups but I found they run better without the choke My 10 cents
You mention Double Pumpers. Is it the same for Single Pump/Vacuum Secondary Holleys?
Holley 3310 vac secondary here. As Paul said a couple of jabs and presto. I was out last week in 20 degree weather warmed right up and went. The key is having your car tuned correctly.

Sometimes a choke is a good thing. Set up properly they can make life a lot easier. I use electric on most of my stuff. Picture taken as I was digging it out for a little road time.

Hot rods being a little more work to drive is part of the fun! No choke, three on the tree, maintaining drum brakes, big cams that have personality, muscling manual brakes and steering, all that kind of stuff is part of the danger excitement and manlyness of the old car hobby.
this is why I drive old cars/trucks with no choke,lumpy cams,manual shift/brakes/steering.
takes more driver input to fly it straight.
the preventive maintence is something for me to do as a hobby.
no chokes needed in FL.
