Here in FL we do have power surges/outages on a weekly basis. I have not had an incubator drop more than a degree over 1-2 hours yet.

That being said I do have a 5000w Honda generator handy that is set to back feed the entire facility should power be lost for any significant period of time. Just test ran the generator yesterday as a monthly "pm". I let it sit for a few years, and when I went to use it last season the carb was all gummed up. Since I got that cleaned up, I run it every month then shut the fuel line off and run the carb dry.

I'm all for saving resources, but this ethanol fuel is the pits!! It has trashed fuel/water separators on my boat every few months, so I just went to a fuel filter, since I have NEVER seen water in the separator bowl.
