the more complex adjusting of the fuel comes from the mixture control.
I don't understand the mixture control, either. Fortunately I can
have MSFS worry about that.

I'm surprised at all the fiddling that pilots are expected to do with
their propulsion units, as compared to other types of vehicles. Bad
enough that one must know how to fly, but apparently one must be a
qualified engine mechanic as well.

Have you ever driven a non-turbocharged car from a low lying city up into
the mountains, like above 5,000' MSL? If you did, you would understand why
the pilot has to manipulate the mixture.

Also, the design of the aircraft engine is such that once it is started,
the engine driven magnetos provide the spark to keep it running.

Yes, doens't that remind you of a basic lawn mower engine?

Not really. Granted, I'm not a lawn mower engine expert, but I believe
they are two stroke engines, yes? Completely different than a four
stroke piston aircraft engine. Going farther, a turbine aircraft engine
generally doesn't stop once it starts running, and I'd hardly compare
*that* to a lawn mower engine.
