Where to buy Carburetor Rebuild Kits.

No Dan. Daytona's doesn't meet the description of the claimed improvements in said patents.

Maybe not, but the "Daytona Float Valve" in the Carter BBS and BBD carb kits I bought from them was an identical, exact match for the "Duro-7 valve" in the old-stock Tomco Carter BBS and BBD carb kits I had on the shelf at the same time. ¯\_(ツ)_/¯
