now if this is out of place then say so....

for winter storage of my boat (outboard engine) i would fill the carb with a product until it would stall. then I would pull the plugs and fill the cylinders with oil.

with that said, i am suggesting putting some oil in the plug hole then hand turning the engine over with the plugs out before the "startup". this would do what you're intending to do with WD40 but not adding another chemical to the engine. if too much oil is put in the hole then you'll have to clean the plugs after you're running.
