I have a 9.9 Evinrude outboard that I loaded with Rust Preventative Oil thru the carb and directly into cylinder from the spark plug hole. This was done while engine was not running, obviously. I then stored the outboard in my cellar for approx. eight or ten years. When I turned the flywheel by hand yesterday, it felt as though the oil had gummed up as it was alittle difficult to turn over. My question is, should I wash the engine out with either some fuel or WD-40 before attempting to start it so it won't seize up?
