How I fix the Honda Generator EU2000 Surging on smart / eco throttle idle 

Great video. Fixed the surge instantly. I'd give 10 likes if I could.

If I could give you 100 likes I would. Mine ran my rv with AC running all day July 4th at the beach no problems. We are getting ready to leave for the Tetons and I changed the oil and it started doing this exact thing. No time to send to mechanic. Then I remembered Im a RU-vid engineer and you came up first. I will be doing this tonight. You might have just saved my trip or the money for a new Generator. Thank you so much!!!👍🫡🙏🏻. You are the man!!! Thank you for taking the time to make such an easy video and making it simply to understand without all the extra talking. Perfectly done sir.

Awesome advice! Had the same problem and stumbled onto your video. Great instructions and fixed the generator within minutes. Got tip about cutting the wrap as well. Thanks!

Thank you so much for that video. I fixed my first issue (ran only on choke), but had this crazy hi/lo idle once I moved off choke. This video solved my issue! Luckily I went to the Honda dealer to pick up a kit so I had the o-rings that were wasted on my generator!

My generator was doing exactly this. Your works steps worked exactly the way you said. Thanks!! 5 minute fix.

Thanks for the tip. Had a similar suitcase generator surging in ECO and this fixed it, thank you.

I took your advice from your video and it fixed my EU220i, the local distributor would not even consider warranty and wanted to sell me a carburetor. Thank you.

I have this exact problem, was going to take it to a Honda shop for a repair but I think I can do it myself! I owe you a beer…. Lol thank you.

Followed a few videos on youtube regarding this issue on my EU2000i, i cleaned the carb many times on and off, changed the fuel and it was still hunting and would only work on choke. Then I had a thought while lying in bed, "Mmm the 5 turns for the low idle screw, could it be not enough?" so today I got a small crosspoint bit and tightened the idle screw one turn. It works a treat now. I was getting to the stage of giving up tbh but glad I didn't.

Thank you Kind Sir! Fixed my surge problem 😊. This easily saved me $150 had I taken it somewhere. (Based on cost of living here in Southern California)

Thanks for a great fix, my EU2000 would only run with choke half on. Turns out the jet was dirty, ran a piece of copper wire thru that hole in the jet and lots of white caked stuff, could see all of it with a 20X magnifying glass.🙂

That link you for this i’m pretty experienced with carburetors but I thought that was only an idle adjustment but now that makes more sense

Thank you so much for sharing your knowledge. You helped 100%. Have a great day. God bless you.

Thanks so much for the video. Worked like a charm . You saved me a bunch. One little thing I did different was to remove the side plastic cover on the exhaust side of the generator to allow me to get a screwdriver and fine tune the idle speed by adjusting the idle screw when I was done.

Thanks, I fixed my generator which has similar problem.

Thank you. I had the same problem. I used a rogue bristle on on brass wire brush. There was a particle smaller than a grain of sand. Works great now.

Thanks my unit now RUNS Excellent !!!!!

Thank you! Worked for me.

This part is sold as - jet set pilot #35 I tried the screwdriver twisting method but it snapped off. I’d recommend lubricating for some minutes before trying to pry it out .

Great video. 👍🏽

Excellent video.... The other jet can cause the same issue....

Fixed my idle surge, thanks. I adjusted the screw with the engine running, seemed to have no effect. Only adjusted 1/2 turn each way.

Easy fix thanks to you! 🎉

Thank you sir I just fixed mine 🇨🇦

The hole is about the size of a wire from a wire brush.

My eu2200i was surging but it was due to a dirty filter on my window a/c unit. I also changed the spark plug.

Thank you

Cool video. I had a slimier problem with a EM600, but it would surge when coming off a load. Hay by chance do you still have any wheels for a Sportlawn? I can't seem to fined a way of messaging you through RU-vid.

Hi! I'm working on an EM7000is, same problem but only when on full throttle! Any ideas? I already cleaned the carb, and the tank/filter.

Hi, I would like if you could help me I have a honda inverter eu2200i, with broken side covers, but trying to find them I only find covers for the eu2000 model, like the one you are building, you think these will fit the eu2200i model, thank you very much in advance

Hi , so on mine EU 2000i , it wasn't starting at all , I've cleaned the jets on the carburetor , used a torch to burn the built up carbon in the muffler and spark arrestor ,and changed the spark plug , started up like a champ I ran it on idle for about 30 minutes. Then it started the up and down surging . I checked the spark plug and the tip of it was all black with carbon . Now when i was replacing that little black jet with the O -ring , I had a hell of a time getting it pushed down . Any suggestions as where to go from here ? Help help ! I'm not a mechanic ,LOL so be gentle

Mine runs fine on eco mode green light comes on no problems under load. When eco mode is not on green light will come on and when put under load engine bogs down and green light goes off. Any suggestions already cleaned pilot jet

Mine does the opposite- runs as if always on eco throttle. Tries to rev up then drops back down. Is there a fast run circuit that could be blocked?

Thank for the video - how can you determine the air-jet (in your video) is the problem vs a clogged carb fuel jet? I’m having a similar issue with a EU2200i that was stored for 3months with non-oxy fuel and stabilizer? My 2200 had about 10 hours on it total - so quite new. Trying to determine what my particular issue is?

I see you wrote "Aspen Fuel Only" on your generator. Can I assume you had carburetor problems on regular gas and switched to Aspen fuel after this fix? Aspen alkylate fuel should prevent gummed up carburetors. Does your Honda run good on Aspen?

Is there supposed to be a tiny hole in the far end of this plastic jet, other than the two rather large holes on its flanks?

Hi i have a little different problem. It was surging all the time. I had to use it half choke , then i cleaned the carb changed the spark plug . Now it works fine and all of a sudden it surges then it stops itself or i give some load on (like hair dryer) then normal again. I really dont know what to do next !!!!!! Any suggestions? Thank you great video

Thanks

my generator runs fine full throttle underload but stalls on ecomode within minutes. any help would be greatly appreciated!

i did exact in the video but now my ECO button dont work. nothung happens when i press the ECO button. not sure what is the problem.

I tried cleaning the main jet just like you did and nothing happened. Mine starts good with full choke then when I set the choke to run it surges. But if I keep the choke half way runs smooth

You didn’t clean that jet on camera. Does the hole run the full length of the jet? Or does it stop where it meets the perpendicular hole??

This should b typical for similar generators?

Hi... Its the same on eu22i?

I tried that on mine didn’t work the idle speed was actually to low on mine

Why does my eu2000i cut off under load?

Strangely I just installed a new OEM Honda carb on my EU2000i and it does this in eco mode. Any ideas?

Informative video and a whole lotta talking.

That engine breather 'heater' is mostly cumbersome , and useless (unless you're living in Antarctica - but even then it wouldn't work right imo. First thing to do on any Honda generator is to completely remove the crap and replace it with a simple hose . Some even go as far as routing that hose straight to the atmosphere , then blocking the air filter nipple (mine has a cute little M6 bolt threaded into it. , but I won't tell anybody. The trick here is to not permit old gas to block that tiny pilot jet : Empty the tank, start the engine till it dies out, unscrew the float drain every time the generator is stored for more than a few weeks (months ?). Use non- ethanol + stabilizer , too. There's no way around it . This all takes 5 minutes once a routine. I think Honda's Inverters are too complcated to work on , but will last and last with no issues if oil is changed frequently ...and of course if gunk is kept out of carbs.

that will fix it over and over and over again.................in other words it keeps on happening in my case.

Don't forget the main jet

so the only thing we learned is theres a hole perhaps the width of a human hair that is involved in something
