Not real well. Once you get lean of peak, the engine gets real
sensitive to the mixture. Very slight adjustments make for very
large rpm changes. It doesn't shudder so much as just die.

My experience with sensitivity is the same as yours. The hardest part
of setting power with mixture only is that the mixture is at least an
order of magnitude more sensitive than the throttle -- there's only a
tiny range of movement between full power and cutoff. I generally
take the throttle friction lock off while very gently nudging the
mixture lever, then put it back on when I have the right setting.

If it dies without much shuddering, then the distribution is
probably pretty good, I'd guess (as a non-technician).


All the best,
