The bigger worry is letting the engine sit too long. Just start it up for a few minutes every few months to give it a bit of a refresher and to make sure it does work for when power outage does roll around.

Hate to correct you but YES gas does go bad, it will lose it octane level & get watery. It will kill spark plugs and pistons quickly in small engines. Any gas that is going to be stored for more then 6 months should have a stabilizer added to it. This is why you need to drain fuel out of motorcycles during the winter and I should know as I have 3.
