I have changed a lot of carbs over to the Annular Booster over the years.
Low speed drive-ability is improved for sure.
I have had my booster tool for 50 years. Not going to wear it out in your lifetime.
People over the years have even added more holes to the booster insert to improve signal with the larger 850 carbs.
The Annular Booster is a drive-ability "fix" for the larger cfm carbs 4 BBL or 2 BBL.
I have converted quite a few of the #4782 & #4783 2-BBL carbs over to the Annular Booster. These are mechanical secondary 6 pack race carbs.
