Could someone tell me what the actual date is on my quadrajet. The carb number is 7041202 with B1 DG below that. I know it is a 71, but what is the actual month and week. Thanks in advance.

Look and see if you can find another number on the carb. It should be a simple 4 digit number like 1551.

The first 3 numbers will be the Julian date for day of the year (155=155th day of the year), and the last digit will be the year of production (1=1971, 1981, or whatever).
