Here's my non expert opinion on your question. For the carbureted version, it's simple. When you start the engine with the engine cold, you need extra fuel in the mixture as some of the fuel will condensate on the cilinder walls. As the engine warms up and the fuel will enter the cilinders in vaporized form, the extra fuel is not needed anymore. My understanding from fuel injected engines is that the injectors do a much better job at vaporizing fuel compared to carbureted versions. When starting a fuel-injected engine, we use the electric fuel pump so the injectors vaporize some fuel into the intake just before the intake valves prior to cranking, and when cranking we wait for the engine to "catch" and then go rich on the mixture so the injectors start spraying fuel again and get into normal operation. I hope this makes sense, let me know your opinion. Cheers!
This was a perfect video for learning the procedures for them.
Thank you, much appreciated.
Great Video !!! Now i can start an engine of an airplane and steal it 😊
Don't forget to pick me up when you do! 😜
Why do carbureted engines require full mixture when cranking vs direct injection that only requires mixture to be full rich when engine starts?

@@LeantoPeak Thanks!! This makes sense and is what I was thinking!!
@@Mattblackaviation787 cheers bud, my pleasure. Blue skies!
Great video! I lived in Köln mit mein Frau and always wanted to fly there, love seeing your countryside, subscribed! 👍👍
Köln is definitely on my list to fly over. If not this year, next year for sure! Thanks and cheers!
