I had a chance to look at it more closely tonight. Jason, you were kinda right. Although I had everything hooked up correctly, the extension throttle spring, (#29) has been stretched and doesn’t overcome the friction of the throttle shutter, so it was effectively like it wasn’t hooked up at all. I’ll either have to try and find another one, or cut this one shorter and reshape the hook.

If I understand how it works, the spring tension keeps the cam roller tight up against the follower, and moves the throttle shutter (#32). The rod links up to the cam lever (#43), and that’s connected the the air shutter (#60). 😕
