Just what I needed ❤

I had a Bendix PS5 pressure carb on a 150 HP Lycoming in a home built Pitts S1. It worked great for full inverted flight. Fortunately, the PS5 never required any repairs during my ownership of the Pitts. This was around 1974 - 1976. I'm thinking the PS5 was the best inverted fuel control device that preceded fuel injection systems of today. Perhaps someone more familiar with the history of the evolution of inverted fuel system technology could comment.

Really great video! I'm studying for Powerplant Written Exam. There's a question:" An aircraft engine equipped with a pressure-type carburetor is started with the...?" Answer: "primer while the mixture control is positioned at IDLE-CUTOFF position." Do you know *why* this is the starting procedure for a pressure carburetor? Why not have the mixture control set to lean or rich? I'm reading that once the engine starts you immediately move the mixture out of the CUTOFF position. But why is it necessary/desirable to start the engines in the IDLE-CUTOFF position? And it seems like with it in the IDLE CUTOFF position little to no fuel would be available for starting. I don't get it! Thanks for the great video.
