Learning about how the carburetor works on my grandfathers (PA-24-250 Piper Comanche) normally aspirated Lycoming O-540 engine.
In this video it shows the external movements related to Carburetor Heat, Mixture, Throttle, and Prop Pitch, with the engine fully together and the cowling removed.
This video is directed to someone who already has the engine theory down, and wants a visual representation.
