Jon,

You should also add some gas stabilizer to the tank in the proportions
listed on the product.  Gas will form varnish over time, and the higher
volatility components will evaporate as well.  Before storing it is best
to leave one or two gallons of stabilized gas in the tank, and then fill
up in the spring when you drive it again.

Also, starting and warming it up once a month is a good practice, it
keeps the oil on the bearings and cylinder walls.
