Joe---- when it stopped was it instantly or did it act as if it starved for fuel or flooded? That POP could have also been part of a very rich issue due to the fuel system dumping fuel into the exhaust and igniting it before the eng quit. Even in a climb the prop should not lock up unless something seized, you ruled that out already. Ignition issues will not lock up the eng in flight unless the timing gets so far outa wack that a cyl fires while its way advanced. I'm betting on the fuel sys or ign. Kenny W
