Not to pick a fight with anyone, but I really have a “dislike” of WD-40 for anything with an engine. It works for squeaky doors and such, but WD-40 is not an engine lube. WD 40 evaporates and takes any oil that is on the cylinder walls. I have used it to clean, but then follow up with proper lubricant. I know some guys who think WD-40 is a curse word and they won’t even have a can in their shop….

In the case of engine storage (any engine, i.e., two stroke or four, single cylinder or V8), I recommend removing the spark plugs and spraying a bit of "fogging oil" (available at NAPA, Shucks, O’Brien’s or any such parts house) into each cylinder. When you have about a tablespoon of oil in each cylinder and with the plugs still out, turn the engine over by hand (with a bar and socket if necessary) for several revolutions. Re-install the spark plugs (hand tight) putting a little dab silicone grease on the threads and bingo – you’re good to store that puppy for a long time.

Don’t use WD-40 as an engine lubricant - it is a water displacement formula.

My two cents,
Glenn
