Honda generator-carburetor

I own two Honda 2000i generators, purchased in 2009. They have served me well, however a problem came up. I have put fresh gas with Sta-Bil in the generators, and have exercised them often (not quite the once a month, but frequently).

Earlier this year I used one of the generators in the desert near Quartzsite, AZ. After using it, it was not used until I went to exercise it in March, and it would not start. I took it to a Honda shop and they diagnosed it as having water in the carburetor. So I had them fix it, for $65 and returned it to me. It ran, but it sounded "funny".

It was in August that the funny sound turned into a large surge. It was like it was dying. The Companion generator did no such thing, it was the regular 2000i. The gas was fresh, only a day old with Stabil. I put Seafoam in the unit, and it helped the unit, but it still surged. In it went to the dealer and they said the carburetor was bad and needed replacing. The did replace it, to the tune of $107, and charged me only for the part, and waived the labor charge.

What could I have done to prevent this? Why did one fail and the other did not?
  • At the beginning of TECH Issues there is a "sticky" LOOK AT IT on Honda carbs. Drain the carb. Would you rather have a hard start or would you like to to start and run like ...t? Really your choice.
  • my thoughts are the gas you used had ethanol in it which caused the water.Try to find and use only non ethanol gas and your problems will be over,or run the carb and tank dry.
  • the carb is real easy to work on. there are some videos on how to repair them.
  • I always remove the gas from mine and drain the carbs if not in use for some time. I also have found that premium fuel seems to cause less problems. I never leave SeaFoam in a gen while inactive. It works great for me if I have one that is not running as it should and I run a mixture through it as long as I am using it.

    Draining the carburetor/fuel tank works well for me, if they will be inactive for 3 weeks or more. Pure luck.

    They don't need "exercising"

    Yes, but it beats the pain of a repair shop.
  • Some interesting points. The consensus seems to be, drain the fuel out of the carburetor. Agh! To start it again is such a pain.

    The thing is also, what about the Companion generator? It was started at the same time, with the same fuel. Why did it not go bad?
  • I always drain the carb. on my Hondas. It is very easy to do, just open the screw on the bottom of the fuel bowl.
  • Some carburetor main jets will clog no matter what type of fuel additive is used. They are just prone to this. A solution might be to totally drain the fuel system rather than trying to treat the gas.

    I used SeaFoam in my Honda generator and had to have the carb cleaned. I think SeaFoam works too well and all the little dirt and crud in the gas tank gets cleaned out and goes right into the carb. The jets in the carb get plugged. Blow the jets and passageways out with compressed air and use some carb cleaner after using SeaFoam on an older generator and it should good to go.
