Personally, I do not agree… as the above information is from a knowledgeable person who is basing his opinion on heresay.
I always thought that the ‘AFB’ designation on Carter AFB carburetors stood for ‘Aluminum Four Barrel’…. regalbob will no doubt come back with info that indicates that ‘AFB’ stands for ‘Anderson Four Barrel’!!!!!!!!
No, ‘WCFB’ stands for ‘White Cast Four Barrel. (my opinion)
Also, I highly doubt that a Carter WCFB carburetor, although heavy, weighs “over seventeen pounds”!
