Hi Chris,
The only answer is they must be from a CB160 i had one as a parts unit, also had 2 CD175 early model with no frame down tubes in front the motor was part of the frame structure. In the 60's and early 70's all distributors of Honda motorcycles were independ from Honda so they could bring what ever models they thought would sell in their markets, that is why you may see certain models in certain parts of the country as well i suppose some euopean models could have been shipped here although Honda did not make different models for different parts of the world as they started to do in the late 70's now they have the same models through the world other than some very small motorcycles, interesting how things change but stay the same. I suppose these carbs could have been from another manufacture, although Honda used Keihin carbs only.

So now I look to the 60's 160's. And even if I do find them, I still don't know what to do with the air jets though.
