Leaning
Absolutely agree. Mid west USA at 6,800 AMSL, leaning is esential as soon as the donk fires. Have another fiddle about at the hold for the power checks to get best smoothest running and than continue to fiddle to get best running in the climb and cruise ... give it a touich of rich in the descent to make sure it still runs OK at circuit height..
Was quite a bit leaned at (ahem) 11,999 feet.
