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

If you have a Honda EU2000 or EU2200 generator that surges at idle low rpm when you switch on the smart throttle / eco option, this might help you fix the problem, this fix generally works for any Honda power equipment that surges. Sometimes running the machine with the choke slightly applied will rich the air / fuel mixture enough to smoothen it out, but this really isn't the proper way to fix it. You'll need to remove the side cover and then carburetor. Be careful not to loose the small throttle spring under the white bracket mounted to the top of the carburetor.

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

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.

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.

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!

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.🙂

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.

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 Youtube 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.

Good info. I have the sam issue, but the opposite. Runs smooth at idle, but surges when eco is off. That's a start, thogh. Thanks

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

[douggolde]

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.

[AKBurgers]

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

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

[frankciongoli]

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

[pawnswhyte]

Thanks, I fixed my generator which has similar problem.

[douggolde]

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?

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?

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 .
