Identifying Your Carb:
Factory Toyota carbs were manufactures by Aisan. Aisan stamped a date code on the top of every carb. While this date code is the absolute indicator of the actual manufacture of the carb, there are instances in which a replacement carb can have a much newer date code than its actual design. However in most cases the date code is an excellent means of identifying your carb.

How to Decipher the Code:

First Digit: (Numeral) is the last digit of the year. Ex. a 2 could be 1962, 1972, or 1982.
Second Digit: (Letter) corresponds to the month. Ex. A = January, B = February, etc.
Third/Fourth Digits: (Numeral) corresponds to the individual batch of carb's.

Examples: 1D6 = April of 1971 or 1981, which would easily be narrowed by identifying the remainder of the carb components.
