The amount of air flow is governed by the venturies.

Removing the choke section of the carb allows for air draft and a better flow to the venturies.

People remove the choke section to allow clearance and to improve the ability to pull air from everywhere as David mentioned.

You can simply purchase a carb section that does not have the choke section from Holley or some third party supplier.

It is an easy swap and may take up to an hour to complete.

May I suggest you secure a new section without the choke and keep the old one in case it doesn't work well for you. My car likes the choke when it's cold outside, but it loads up a little if it isn't allowed to reach running engine temps.
