Can you not buy ethonal free fuel at the pumps? Here in Florida it is everywhere maybe because of all the boats with outboard motors?A quick note, I use 3 Honda generators for various reasons, a Eu1000i, a Es5500 and an Eu6500I. All of them will suffer from ethanol gelling in the jets if they don't get used for 3 weeks or longer. To prevent this I use 100 Low Lead Avgas. It's ethanol free and can sit for over a year.
If a gen is hard to start, or won't idle unless the choke is used, it's probably suffering from gel in the jet.
