My EU2000 is about five years old and was starting to run a little rough. I figured it was probably time to clean the carb, and thought I might as well take pictures and post up a little tutorial for those thinking about doing the same thing.
The whole process took about 60 minutes. While I was in there I also changed the oil. The spark plug is only 8 months old so I left it alone. After I was done, I went and got a gallon of fresh premium gas and it fired right up. It’s running a lot smoother now.
I can only assume this procedure is the same for the EU1000. EU3000 and above, you're on your own.
1. Locate your EU2000 and make sure it’s empty.
2. Remove the side panel.
3. Remove the air filter cover.
4. Remove both air filter elements.
5. Using an 8mm socket, remove the single bolt inside the airbox and the two nuts holding the airbox on to the carb.
