as mentioned biggest issue is the gas. Now the newer honda 2200 have a "run dry" feature you can use when you shut it down to keep the generator running till it runs out of fuel in the carb. It shuts off the fuel pump.
You easily add the same feature to an older honda 2000 as well. Or just drain the carb with the drain tube if it's going to set for a while (> month)
In addition use sea foam in the fuel. I've had way better luck with it than stabil. never had an issue with gumming, varnish etc with sea foam. Did with stabil.
