Hey, I’m new to this forum. I’m looking for some help. I recently bought a 63 F100. I’m trying to rebuild the carburetor but I can’t figure out how to identify the list number. It’s a holley carburetor. I’ve been through Holley‘s website and been looking on the Internet but the numbers I’m seeing on the carb don’t seem to be listed anywhere. I’ll post the pictures but here is the numbers I have.
stamped on the right side: 6R 3806 B A-1
there is a sticker on top with the numbers: 5143. 2255-999900
also on top is another sticker. I noticed it says Remanufactured by Holley




any advice would be appreciated!
thanks

 

I dont know about the really old Holley's but the list number is on the front side of the choke horn, right side when looking at it from the front.
Other wise 5143 looks like it could be it.
I think it is Mike's Carburetor can help you find the needed numbers and get you the needed parts for a rebuild.
