When I shut off my generator I do it by turning off the fuel that way the carb has been drained and since O always have the fuel tank full I add seas foam. I run the generator twice a year for at least an hour maybe 2 just to make sure it works well. Every two years I drain the fuel and put in my lawn mower or car and then I add new fuel to the generator.
