Dustin answered 14 years ago

the 12A in all of its forms was produced between 1970 and 1983. The 12A as seen in the RX-7 with a carburetor, was 1978-79. If you could provide the casing numbers, information on the carb, or other clues I could probably pinpoint the exact year, assuming the parts are original.
