EU2000 carburetor cleaning

You won't need parts unless you lose or damage them when taking it apart.

Try a good carb cleaner first. Lots of people like Sea Foam. I don't, just a personal preference. Techron is the best there is for this issue. Dump all fuel out, put in some top tier detergent gas (like CostCo), and some Techron, and run it for 15-30 minutes. Shut off and repeat the next day. You may have to do this several times.

I've cleaned the carburetor on my eu2000i many times in the last 10 or so years, and never had to replace a single part. I would just take it apart, clean the jets and orifices and put it back together. Floats typically don't wear out. Just set it aside where the carburetor spray can't get on it and reinstall the original. I never spray the plastic float as years ago I destroyed a float on a small engine that way. You need to pay careful attention to how the main jet comes out of the center. there is nothing to prevent you from installing it backwards, you just have to be careful.

put a couple of ounces of sea foam in it and run it for 30 minutes with eco off or so, then let it set overnight and repeat.

If that works, your home free. If not it may need the carb taken out and the pilot jet replaced. I say replace since at least on many if not all, the pilot jet is plastic with an extremely small orifice. to small to reliably clean without reaming the hole out.

Seems to be a common problem with this model of Honda generator. I'm having the same problem with mine. Sea foam has helped but not fixed entirely. Still surges at times when on ecco throttle.

I don't know the specific answer to your question. One of mine ran rough - I put some Sea Foam in the tank. After maybe ten minutes, the rough running cleared up and it runs fine now.
