One more note on the subject of generators. If yours uses a fuel line, you may want to plan on replacing those at whatever schedule you find makes sense for your application. Because over time they will break down, decay, and start to leak.
I always use non-ethanol gas and tygon material for my fuel lines but I also keep some bulk fuel line on hand just in case. I keep it inside my climate controlled home. Generator stays outside under cover year round. The spare still in it's box is in my garage - which is climate controlled via window unit.
I'm probably a bit obsessive when it comes to some of this stuff....
