Assuming all existing parts are in good shape, what needs to be replaced? One video I watched stated the large O ring type gasket between the float chamber and carb body, as well as the float valve seat need to be replaced anytime an overhaul is done. Is this usually true?

Actually that is the gasket that usually survives because it is made out of neoprene ! Do not clean that gasket in any thing except warm water and soap. Many carburetor cleaners will cause it to swell and then you can not re-assemble. If you find that it HAS swollen. wash in warm water and dish soap and let thoroughly dry.

If you are going to replace the main jet (31) (up inside the tube that holds the emulsion tube - 12) you need a special screwdriver. Briggs makes them or buy a "gunsmith" hollow ground screwdriver. Not expensive. (Typical straight blade screwdrivers "flare" outwards and can not reach inside the tube where the main jet lives.)

There are a couple of "hidden" passages that you might want to TRY and get to. #5 is idle/pilot air bleed adjustment. It is covered by a cap. By careful if you try to remove the cap as the screw may BREAK https://youtu.be/kMw91fiIXNc?t=242 ! Also #32 is the idle/pilot jet. It is plastic and goes straight down into the carburetor and held there by the throttle stop screw (11).

I've never overhauled the carb in my 16 year old EU2000 so I'm not sure why you would want to. There really is no rebuild "kit" just a couple of rings. There's a large o ring for the float bowl that should be replaced but that's about it. There's nothing wrong with your carb so why consider replacing it with a cheap aftermarket one? A genuine Honda carb is over $150 but why spend the money?

In summary there's nothing to rebuild, only a bit of cleaning to do if the carb is really gummed up. Tons of YouTube videos will show you how.

If you're just replacing the main jet I do that, clean what you can, and move on

Old Wizard:

Thanks, good info.

On further evaluation, and based on how well the generator is running, I think I'm going to be satisfied just cleaning the main nozzle (emulsion tube) part # 12 and installing the high altitude main jet. At this time I don't think further break down is needed, but I will store your info for when it is needed.

I have a set of hollow ground screwdriver bits so jet removal should not be an issue depending how far down in the tube the jet is. Good to know the large O ring is not an issue. I will treat it with caution. The generator is new enough that I don't think the 2 flange gaskets on the carb body will be an issue either.

I'm still considering getting one of the $35 generic carburetors and putting the high altitude jet in it. It looks easier and quicker to swap carbs when needed than to have to disassemble and change jets.

I have a 2000i that is setup for sea level. I have been at over 10,000' elevation and the generator will still power the A/C unit.

I'm not sure a lot of people know about the carburetor drain tap...including the person below.

Ditto. I have two 2000I. I lived for 30 years in the Denver area at a little over 5,600 ft.

Both generators have standard jets.

When I bought them I took them to the dealer to get re-jetted and he told me not to bother.

I ran them at elevations up to 12,000 ft and never had a problem.

Since retiring to Florida I let them stand too long with old gas in and the carbs needed doing. Cleaned them both out in a day and got rid of gunk and water. Both run like new again. Not bad for 16 year old units.
