I have an A12 Bee and my bud just bought one. We are comparing carb dates based upon a story of the seller. My Bee’s motor was built on March, 28 and the vin is 2626##. His car motor was built on June 12 and his vin is 3029##. My question is my carbs are dated 102 and 104 for outboards. My center was a 71 changed out long ago. I’m pretty sure the outboards are original to the car. I know the owner from 72 to date. His carbs are dated earlier than mine. His are supposed to be the original carbs and dated 093,092, and 087. Seller claims that the normal first in first out with parts was not followed on these A12 cars. He claims the opposite. This claim seems to follow our two cars, somewhat. I’ve got lots of oem 69.5 carbs I’ve bought over the years. I’ve got date codes ranging from 072 to 198. Anyone have more information to add?
