Lycomings shouldn't be pre-start turned either way as the oil pump won't deliver and dry metal to metal contact will cause wear if prolonged hand turning occurs
Though equally possible with any engine, I would not be the least worried about this effect for the amount of horse power I can personally produce. The engine does not know what force is turning it over, just that it is. A dozen revolutions on the starter motor would have the same result as hand swinging the prop.
I agree that an engine which has not run for many months probably would have a delay picking up oil through the pump, and this would result in some dry running. If this is the case, the rather loose fit oil pump is well down the list of components about which I would worry. Crankshaft bearings, and for Lycomings, the high camshaft bearings running dry would worry me more.
An excellent reason for regular operation of engines! Let's all fly more!
