Now that's bull****. Aggressive leaning is COOLER when done properly
(i.e.,
using the proper temp range when LOP. It also produces lower internal
cylinder pressures, more through combustion, lower CHT temps.

Not in a carbureted engine.

Yes, in a carburated engine.

The fuel flows are simply not matched well
enough between cylinders to run lean of peak without risking damage.

That's a seperate issue, but even that's not completely right. The issue
there is the ****ty fuel distribution in horizontally opposed engines. That
includes carb engines and FI. The issue IS the sloppy (horrendously) design
and workmanship that the two big boys have been getting us schmucks to buy
into for the past couple generations.

Go and read about the P&W radials and how they ran them during the
carburation days, then put the book on display in your hotels library.


Now, in a fuel-injected engine (especially with GAMI), that's a whole
different world. But in the low compression carbureted world, you run
rich of peak, or you risk destroying your engine.

You run rich of peak in the wrong range and you still mess up your engine,
high compression or low, Mogas or Avgas, carbureted or FI'ed.
