Would like to understand logic behind hot start suggestions
I am not in need of suggestions for hot starting procedures--there are many posted indeed. But I want to understand those procedures and in turn better my understanding of the fuel injection system. My plane is an early model, and while the engines hadn't changed materially in this regard (to my knowledge) I know that some of the fuel plumbing may have. So if there are any substantive differences in the later models my diagram and logic here may not apply.
Looking at the attached, it looks like the throttle ("power") control is downstream of the mixture's on the fuel's journey to fulfillment. If that is so, why the suggestion (from some) to close the mixture fully, but open the throttle, when "priming" with the electric pump for a few seconds (the 15 or so often suggested)? Any setting after the mixture seems a moot point if you've closed the mixture.
