I double dose my gas and run it like that for a little while to make sure it all gets up into my carb then park it. I never start them in the winter unless there's a reason. I've always felt the potential damage you do to the exhaust system etc from condensation that won't get burned out isn't worth it. Then again, we're talking about a bunch of different climates here...
I change the oil in the spring before I start it.
