question on two Honda 2000is

I have a question/problem with the one of the two Honda 2000i (one of them a Companion) generators. I exercise them on a regular basis. I put the same fuel in them both, with Stabill. The fuel is never over 2-3 months old.

I have a Honda 2000 for my TC, and a Yamaha 6000 for my house. I do run the Honda monthly, but have left the Yamaha for almost a year at a time. I too use Stabill in both. I seldom use the Yamaha, but it still has no issues with starting with old gas. The Yamaha is over twenty years old. I start the Honda every one or two months. It will have fuel issues on occasion, requiring cleaning of the fuel system.

Yet recently I started both of them, and the 2000i (the regular model, not the Companion), had a significant surging problem. It went away in about three hours running Seafoam through it.

When I have that problem with my Honda, the only way I can stop the surging is by cleaning the carburetor.

Why did one act differently than the other generator? Thanks Seafoam for working, but why did one act up and the other did not?

Lots of possibilities. Could be a very small piece of trash in the float bowel. Could be the surging Honda could have got the fuel from the bottom of your fuel can, which often has water from condensation, or simply water drawn into the fuel can by the ethanol in the gas. This can also happen when the fuel is in the Honda fuel tank. If one generator was shaded, it would be less likely for the ethanol or condensation issues to take place.

Will it happen again?

Probably.


Do you run Stabil and Seafoam both in your Hondas?


I have had my Honda 2000 for about eight years. The only issue I have ever had with it is fuel. I have cleaned water out of it several times. I have cleaned what looks like syrup out of it. My Honda is stored (back of my TC) in the sun, as is the fuel can. It helps when I keep the fuel can and Honda full of gas, it definitely reduces condensation. I have not yet identified the syrup substance, but I do think it is related to the ethanol. I am still searching for a solution. I have modified my fuel system by adding a separate fuel filter to made it easier to clean. The filter also works as a water trap, and can be disassembled for cleaning.

I do use Stabil. The last time I cleaned the fuel system, I had some syrup in the tubing, water in the tubing and filter, and what looked like algae (green color) in the filter. I had nothing in the carb bowel.
