My circa-2003 Honda EU2000i had been giving me problems after sitting for an extended period of time. I'd tried Sea Foam, but it still wouldn't run on anything but a full choke. I was considering taking the generator to my local small-engine repair shop but saw this thread and figured I'd give it a try first.
I drained the old fuel and ran through the procedure. There was loads of gunk and rust particles in the sediment bowl. It looks like the sediment bowl is corroding. I thoroughly cleaned everything, and re-assembled.
It started, but I was getting fuel running down the side of the engine. Turns out I didn't go nearly tight enough on the carb nuts. Tightened them down and now it's running great, all for the cost of a can of carb cleaner and some elbow grease.
I had a pressure washer with a Honda GX200 engine that wouldn't stay running either, so since I had everything out, I cleaned the carb on that too, and now it works fine.
Another thumbs up to a great set of instructions.
