Just finished my seasonal winterization, be sure to do yours as well.
My completed "to-do" list. Chain saw, portable generator, 2 riding lawn mowers.
New motor oil. Change or clean those air and fuel filters. Check/Replace those plugs. 1 teaspoon of oil in the cylinder before replacing the plug(s). Use a good fuel stabilizer. In most cases, 1 oz. of fuel stabilizer to 1 gal of gasoline. Pour in the correct amount of fuel preserver. Top off the tank. Run the motor for 5 minutes. If you live in a climate that freezes, get your batteries out of the cold for the winter! You are ready for spring, even though winter is just getting started.
