Hey codger, I am form L.I. (in fla. now) and have been a marine mechanic for 37 years. Top off the tank, this will prevent condensation. Add your stabill and run the scoot to get the stabill into the carb, cly,ect. The best thing to prevent condensation form rusting the cyl., is to "fog" it Remove the air box, and w/ the engine running at a HIGH idle spray PB BLASTER into the carb. You will begin to fog out the neighborhood so do this outside. Spray it in carefully so as not to lock, or stall the engine. When you have done this for about 30 seconds the entire inside of the engine will be protected. Replace the spark plug in the spring, change the fuel and you are good to go. I have done this to thousands of engines over the years. Most folks will simply put them up w/ the lawnmower, and thats where most of the posts about GREAT deals on the scoot that won't start come from.Follow these steps, and you will ALWAYS have a scoot that starts in the spring just like the day you put it up.
