I'm not sure I see the value of doing an engine check while flying the plane, or flying carbureted engines without automatic mixture control in general.
Pilots will understand their engines' quirks better, but those quirks are stupid and obviated by newer technology.
Forget mixture, carb ice keeps killing people in 2025. Even just moving everyone to dumb mechanical fuel injection will be a big step forward at this point…
