Re: storing a engine
I'd say the environment of the storage place is probably the most important factor. Clean, dry (not only from surface moisture, but also from airborne moisture), and varmint-free are probably the three most important things. A thin coat of oil on all the interior contact surfaces should be enough.
There's a product that snowmobilers use called "engine fog" that protects the innards for summer storage. You spray the stuff in the intake while it's running and it coats the cylinders and crankshaft with a thin film of oil. For 4-strokes, you also need to protect the cam and valve train.
