    Hmmm…. Now I’m confused. 😕 I was under the assumption that because the the fuel line and the low speed needle were on opposite sides of the rotary intake port, that the fuel doesn’t actually flow through the needle itself like in later carbs, that the low speed needle controlled the air flow.

    Studying the cutaway illustrations more closely, I think I see how it works now.

    Wouldn’t be the first time I was wrong. 😉
