Correct me if I'm wrong, but I think the "idle mixture" does not have
anything to do with high power settings.
All the "ports" open up with full throttle and gives it more fuel than
needed to keep it cool.

Don't know, but that sounds plausible. Thanks for the correction. The same
mixture knob controls the mixture at both idle and full power, though.
