I store mine with the Gas in. However, I do add Gasoline additive to keep the gas fresh, and drain the tank once a year, adding new gas. I dont throw out the old gas, just add it to my truck. Even if the gas is a little old, it wont hurt anything as I am adding 5 gallons of old gas to 25 gallons or so of new gas.
If you store it without gas in the tank, the carb seals will dry out and not work properly.
