I've never heard of anybody being able to run a single-carb aircraft engine LOP - it shakes too much.
I'm sure as a generality that's true. But Deakin and Co at Advanced Pilot Seminars have examples of Cessna 182 pilots flying behind Lycoming O-470s with multi-cylinder engine analysers that routinely operate LOP. That's where the tips have been promulgated of slightly closing the throttle from WOT and using partial carb heat at the higher altitudes. Whether you can truly get all six cylinders LOP and still running smoothly on many of these engines is another question!
