 If I remember my stuff from aircraft maintenance school, there are two
fuel ratios that will give full power (I can't remember the numbers
though). The rich mixture is use to cool the intake charge to prevent
detonation during full power take off. Remember the extreme pressures in
a supercharged aircraft engine at take off power!

 The lean mixtures would quickly destroy the engines at WOT during take
off.

Getting all the information is most of the solution.

I always thought that not fuel gave you more power, within reason.
Someone  
told me tonight that leaner is better for power and more fuel will
result in  
less power but less chance to damage the engine. Airplanes set "full
rich" for  
takeoff and climb to get the most power out of the engine. The mixture
is 
pulled  back, leaned out, in cruise for economy.
 
So what's the "real" story?
