...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
