Hi guys,

I'm trying to restore the Carter WCFB 4bl of my 1955 Buick to the original factory set up. But I can't translate the part numbers of the service manual to actual jet sizes:

THIS IS WHAT THE MANUAL SAYS FOR FACTORY SETTINGS
==================================================
THESE ARE THE JETS THAT ARE AVAILABLE

Anyone here that has a clue how to find the right jet size?

Best regards

Ralph

 

Hi Ralph,
Is there some special reason you need to change those jets ?

I have a carburetor parts breakdown parts book probably with part #s . I just have to get out to the shop to locate it
Can you provide the casting part number stamped on the main body, should be at least 6 digits.
