After talking with Dayton and hearing how when he leans his -4, it goes from running fine, to nothing. He is running duel P-mags, BTW.
Is it possible that these planes are being flown too lean which then triggers Detonation?
George? Others?
Once AFRs get leaner than about 17 to 1, ignition probability starts dropping off rapidly until the spark won't light the mixture off. Engines runs really rough then quits.
