A good idea, re your "...If you mean not to run the engine at all or hand-turn the engine, you may want to remove the spark plugs and give it a cylinder lubricant, turn, and spray again. I forget, yet there exist some rather thick specialty spray lubes you spray into the cylinders to halt corrosion of the rings and cylinder walls...."

It's called fogging oil, invariably in a spray can. All boaters know it, because we usually only use our engines seasonally at best, and then some also use their boats less often than once a week -- so most of us will "fog" our engines for such longer interim periods. Pulling a spark plug and putting the spray in each cylinder lubricates the valve seats, piston rings and cylinder walls; many of us will spray into the carb's throat while the engine is running as well to lubricate its internals (yeah, not many marinized engines have fuel injection yet :-). And of course, in addition to lubrication, being thick, it also holds to those parts and stops corrosion as well (especially important in areas where you go boating, but as good other places as well).
