Just wanted to addy experience to the conversation as well. I bought two Honda EU2000i generators last summer and did no use them much at all. Used them here and there for little things and used once for the trailer. I only use ethanol-free gasoline. I winterized each genny with fresh ethanol-free gasoline mixed with red stabil in early October. Around thanksgiving I decided to try to fire them up and they would not start. It took about a solid minute and a half messing with the choke and pulling the cord until I finally got a sputter and the next pull fired; this was for both gennies.
I did shake each genny to mix around the treatment before trying to fire them and I wonder if that is the reason why mine has such a hard time starting. Also, I have heard the blue stabil is better for small engines.
I drained both gennies and will just refill each with fresh 91 ethanol free this spring when I need to use them. Kind of a pain if you do not use up all the fuel out of them when it comes time to store them.
