mine starts and idles perfect even -20 if I let it idle a minute or two I don't even have to feather it, but who wants to drive when its that cold any how, rub out start car com back in 5 minutes and I am good to go. I have a t-quad with no choke. If the base timing is tuned to perfection and your mixture screws are set right when warm you can give them an extra 1/4 turn open and it will richen it up enough to run god cold. If your timing is compromised at all it will make it harder to get it to run good cold. Also need to make sure your air bleeds are set right, a good quality mix burns better when cold. Also you need to make sure it is not a holley because they ocasionally back fire when the tune is slightly off and blow power valves.
I am not causing global warming, I am just trying to hold off a impending Ice Age!

...That must be why the carburetor manufactures put those chokes there in the first place?
True to an extent....
But Depending on cam, a choke can be totally unnecessary.
My car will start no matter how cold,(although I won't start it if it's older than -15C ) and idle within 1 minute of starting. Has never had a carb with a choke on it. The mix is bang on. Proven on a dyno, and at the track.
Maybe that's why performance carbs don't come with chokes in the first place?

chokes will reduce the cfm of the carb. or better yet, removing it will increase the cfm. I read it in my Holley book. they said that the 600 cfm 2 bbl 2300 series (its was really a 4xxx series but i cant remember the actual number but its in the 2300 section) would rate close to 630 or 650 cfm with the choke plate removed.
thats enough reason for me

I love having a properly functioning choke on my thermoquad. I drive my satellite to work in the spring-fall months. Leaving before 7am some days, I sure as heck don't want to sit there and spend minutes babying the throttle before I leave for work. I don't get up early enough for that, and to a lesser extent, don't want to wake up the whole neighborhood! This way I can pump the gas 3 times, hit the key, it fires, 10 seconds later I kick it down and off I go to work. Even on cold mornings I can take off right away. If you don't drive your car much, I'm sure you're fine with out it. I drive mine everywhere and use it as my daily driver so to me driveability is my primary concern. Besides, with those tiny primaries in a thermoquad, I'm not crying over the idea of losing any flow through there anyway.
