I *can* lean a lot more, push my EGTs over 1500 degrees, push my CHTs

Now, of course, there are many theories on leaning (I've read 'em all),
but with my normally aspirated engine having such (relatively)
unbalanced fuel flow to each cylinder, I don't feel comfortable
aggressively leaning.

John Deakin has written that if you lean to the lean side of peak and
the engine runs rough, pulling on full carb heat will distribute the
fuel into the air mixture better and give you the ability to lean to
the lean side of peak.


Actually, he says "just a touch" of carb heat.

Set your carb heat to whatever setting gives you a carb temp of 40
degrees. You will notice that your CHT's get really close together then.
