Gummed Up Honda EU 2000 Gen

Almost every year I have a gummed up carburetor where it will only run at full or half choke. I have used seafoam. I have started the Gen up every three months to let it run for 15 minutes and still carb gum problems. I saw a interesting Video on youtube where I think the guy had a great plan for running carb dry before storage. I apologize if this has been covered before. On the EU 2000 (and I assume the 1000 as well) the shut off switch not only turns off the gas but also turns off the ignition which makes it impossible to run the carb dry without draining the tank. if you open up the cover on the EU2000 down at the right corner you will see a couple of plug connectors. The one with the black and green wire, disconnect it. Now when your turn the switch it will cut the fuel but not the ignition.. The EU will run for about 2 minutes and sputter then stop. Actually I am thinking about leaving it disconnected all the time... I still will run a Seafoam fuel additive to the tank. We will see how it goes next year when I go to start it up...

  • Your better off draining the fuel from the carb because running it dry will not totally empty the bowl and whats left will dry up and leave residue behind.
  • Running it only once in three months for 15 minutes is probably the problem (with an assist from that garbage, Ethanol). I have had good luck running mine for a solid hour, under a significant load once a month. I treat the fuel with Sta Bil/Sea Foam per the label instructions. Yep, takes a half a dozen pulls to fire off sometimes but it always does and then runs smooth. Changing the oil and cleaning/regapping the plug on a yearly basis doesn't hurt.

    YMMV.

  • Your post surprised me. I have had my trusty Honda for many years and have yet to have anytrouble. I do use STA-BIL fuel stabalizer. Wonder if that made the difference. Sounds like your pilot jet is clogged or gummed.
  • I siphon the gas out of the tank and then run it until the carb is dry. For insurance I also open the carb drain. And all my small engines get non-ethanol gas.

    I guess I have just been lucky with mine. I got it in 2008 from Mayberries and it sets secured in the tailgate corner of my covered and locked truck bed. It starts on the second pull just about everytime...

    I change oil in it the spring of every year...

    Maybe the bouncing around of the fuel when I am driving down the road helps???
