    Bill,
    Since I have the engine removed from the frame, I looked at the carburetor and the number was AT7B. Since mine is a early build, I think that should be the answer that you are looking for.

    Thank you! I just wanted to ensure the AT7B carb I had on my 12/70 HKO was correct.

    Bill, Here are the correct carb numbers for the K0 and K1. The jetting information along with the settings are in your Clymers manual.

    K0 - AT7B
    H K0 - HT7A
    K1 - 533A
    H K1 - 594A

    G
    CT70 K0
    CT70H K0
    CT70H K1
