- While troubleshooting a bad idle on my EU2000i, I recorded the process for disassembling the entire fuel system. I did not solve the problem during this time but did confirm that the fuel system was not part of the problem.

What a moron. You have no clue what you are doing.
Thanks for the clicks!
@@aaronsrose Aaron. Amazing video! Great job exploring the unknown and figuring out what you could. I've had that issue before for several years then this year it just quit starting. Mine will fill the carburetor float bowl (so I think the fuel pump is working) and it will run with fuel manually dripped on the air filter, at least until that fuel is exhausted, then it dies. So diagnostically I'm stuck. I'm gonna go back and make sure the fuel pump is air tight and actually pumping fuel.
Thanks again for an awesome video!
ps. we're not defined by what trolls say, but by how we respond. Good man.
Got mine running. Main jet was plugged. Thorough cleaning. 8 pulls fired right up, runs like a champ.
Thanks again, great video.
Didn't change a thing choke still on main jets never touched...
That’s why he did it. Investigate!
I checked that fuel on/off valve more intelligently than you did without having to remove it. I just pulled the fuel hose at the carburetor and switched the valve to the on position and blew into it but nothing happened, so I tried sucking and was able to verify that fuel was indeed getting to the carb. The downside is that everything I had to eat for the next week tasted like gas. Anyway thanks for the video it was helpful.
I know this was done a few years ago but before attempting this teardown I would suggest downloading a free copy of the service manual for this generator to familiarize yourself as to what the parts are and sequence of removal and re-installing. The manual has torque values of various bolts and screws, a full electrical schematic, exploded views of every component, etc. I've taken my bought used generator apart to fix an issue. Looked daunting at first but once I got into it, it wasn't too bad. Don't know about other generators but the Honda is well built of quality materials and components. pretty easy to work on and genuine Honda parts are readily available and relatively inexpensive online. For this reason the Honda is well worth the extra cost over the cheaper competitors. If you have mechanical skills and/or a DIYer you should be able to repair most issues on this generator, especially with the help of RUclips videos. By the way, when removing the Phillips head screws from the case use a #3 Phillips screw driver. Better grip,won't strip. Good luck!
I bought a set of needle drills from eBay. They are tiny and just what you need for servicing a carb. The first thing I learned was the trick with the plastic idle jet. I overdid mine and had to buy a new jet. That vertical hole is tiny.
Next is the main jet. Remove the bowl. Unscrew the jet and drop it out. Next there is a vertical brass jet which might need a little encouragement to drop out. The flat screw brass jet holds it in place. Once out it has about 6 tiny holes in the vertical on both sides of the jet. They become clogged up and a micro drill will gently clean them out. Then reassemble. All these tiny holes must be clean and the tank filter crystal clean. The white powdery substance is minerals from the low grade fuel. It builds up in the orifices and the filter. Excellent video and please do not take any notice of the couple of negative idiots. This was a very valuable video.
Thank you! I've been needing to tweak mine about once a month. I found the a single bristle off my old ratty wire brush held in a vice grip works pretty well. So far I haven't had to fiddle with the main. Hopefully that continues. Best regards!
I am pretty certain my fuel pump is shot so I appreciate watching you tear this thing down. Now I know what mistakes not to make. Thanks
Note: That fuel shutoff valve is the subject of a current recall on these generators. The 2 phillips head screws on the valve were not correctly tightened at the factory and may leak potentially causing a fire. The recall service is free from your local Honda dealer, they slap in a whole new valve from Honda.
Thanks for showing us how to get to the valve Aaron. Juan Nevada City, Ca.
The recall was on the 2200 not the 2000
That mystery piece is Honda’s fuel pump, spent an hour looking online, thanks for the video
I admire your patience stripping everything down but although so very close you missed the very cause of the problem .....the main jet needs cleaning. 1. Remove carb. 2. Remove float bowl 3. With a flat screwdriver undo the main jet and clean thoroughly. 4. Before reassembly make sure everything is clean and free from build up of dirt check all air and fuel ways are clear 4. Re assemble and you should have resolved you lumpy idle issue. Hope this helps you. John
Yeah probably caused by a the old fuel. I would think that would be the first suspect in this scenario. I assume at higher rpm there is enough Venturi to overcome the constricted fuel way.
John, in addition to draining the fuel from the line after use, would adding fuel treatment like Gumout Tune Up or fuel injector cleaners prevent the jet from clogging in the first place in your opinion? Thanks!
Patience, he just did not have a clue what he was doing or why.
This is a great tear-down of this machine. Thanks for taking the time to record your process.
Are you serious.He has called this a teardown. Any fool can unscrew a few screws. He couldn't even recognise a fuel filter in the fuel line.
Thanks for taking the time to share your experience disassembling and learning about your generator. I fixed my surging by cleaning the main and pilot jets, as others have commented. Then, I installed a switch that separates the fuel cutoff function and the shutdown function so you can run the generator out of fuel. Hutch Mountain switch (like you, I made a video to share my experience and pay it forward to the rest of RUclips). I now run my generator every 3 months as preventative maintenance and have not trouble.
After shutting off the gas before you store the generator open the brass screw on the bottom of the carburetor float bowl and drain the gas out of the float bowl. That is why Honda has provided a hose to get the gas out of the of the bowl. These carburetors have a very small gas pick up hole drilled horizontally through the pick up tube that actually picks up the gas. That pick up hole will clog as the gas evaporates out of the carburetor bowl in storage. If you open the brass screw and allow the bowl to drain what little gas may remain is below the hole in the pick up tube and will cause no problem. If you fail to drain the carburetor bowl before storage,I can promise you that you will eventually, usually rather quickly, have a problem starting the generator the next time you want to use it because the hole in the pick up tube is clogged with residue from evaporated gasoline.
Thanks for the great demonstration on disassembly; that was my motive for watching as I have fuel leaking only when running from somewhere between the shutoff Valve and the fuel tank in one generator. Now I see how it comes apart so I can determine what leaks.My two generators have over 200 and 270 hours on them respectively (I keep a log), and I have used nothing but Ethanol Free 91 octane in them; they run just like when new in 2013. I do run them at least monthly. My boat mechanic gave me that great Ethanol Free advice after my second carburetor rebuilt in as many years. Fixed the outboard problem; rebuild free for 4 years now.
Working on every model of every piece of equipment I own and have owned , and everything that others bring me, has been is always like going back to school , and I have never been able to do that for free. Not like grade school . You invest time in research , disassembly , the wrong way, buy parts you do not need, and spend countless hours trying different things. That does not describe the many successes I have had , but is a general rule. I am now too old to quit, at least trying to do my own work, it is hard to find a shop that you can have unwavering trust in.
If you haven't solved the problem yet, it could be the internal parts in your carb. Fuel with ethanol that sits will form gum and varnish. The parts that would get gummed up in the carb are not that expensive to replace, considering how much the gennies cost (I also have two EU2000i's). The main jet, valve set with float, main nozzle are the three things you probably should buy and just replace. You may want to also replace the fuel filter that you thought was the "tube within the tube". You could clean them, but judging from all the youtube videos out there with these types of gennies having idle problems, a slight blockage could cause issues, even though you may think they are clean. After you've replaced the parts above or cleaned everything and if the problem is gone, stop using fuel with ethanol. Also, you may want to replace the gasket on the float bowl (according to my local shop). Here in Canada I use the highest grade fuel from Canadian Tire, which does not have any ethanol at all. Other things you could do would be to obviously use fuel stabilizer when storing, small engine fuel system cleaner, running the gennies at least once a week, and perhaps some Seafoam shot up the carb float drain tube. There's a lot of videos out there on how to properly clean the carb's in these gennies. Just do a quick search and you'll find them.
Agree with a few others that you may have missed the problem by not cleaning the main jet and pilot jet. Small flat head screwdriver down centre (where fuel bowl screw goes into) to unscrew. Take it easy as it's brass so more easily damaged. Tap to get jet out. Clear hole in the brass screw with wire. I use small gauge fuse wire to clean through the holes. some are finer than others. I was trying to track the fuel line from tank to carb for correct location of filter, fuel tap and vacuum for my own project so video was helpful.
This video was very useful. I am listening to my Honda as I type. It is surging a bit but running ok. The reason I looked for a video like this was because I have failed to make my extended runtime hose work properly. There is zero suction coming from the fuel tank. Being as there is a fuel pump there should be suction. This is not gravity feed as is my Predator. So why no suction? I think the fuel filter that sits in the tank is responsible.
It is 15 years old and is probably allowing just enough fuel to go through to run but with a little surging and it is killing the suction of the fuel pump. I needed the information on tear down. I have had mine apart but not quite to the level you did. Carb addressed in a separate post.
The black piece with three lines coming out of it is the fuel pump. It’s behind the shut off switch on the right side.
Great video
If it's running rough the first step is open side panel and turn drain screw on bottom of carb (shown at 10:40) to drain any possible water, debris. That solves my issue most of the time.
The other 2 clear lines are the vents. Black lines are to fuel.
I run these in the winter 40 or so times for 2-3 days and the fuel separates and the ethanol is at the bottom and is usually the problem.
Rough coment crowd.
Thank you for the tear down.
I learned alot....👍
Lol. Yeah the solution I was looking for was a lot simpler than I made it. I figured some people would find the teardown interesting. Thanks!
I think it might be your throttle control module (white device on top of carb). Changed mine and it fixed the problem. I was having exactly the same issues as yours. Worth a try.
You have a plugged pilot jet, remove the idle screw, pry out the little plastic pilot jet clean the TINEY ORFICE with a piece of strand of copper wire
Followed with some carb cleaner, reassemble by installing the pilot by pressing all the way in, reinstall idle screw until it bottoms out, turn it exactly 5 turns out, now your Honda will idle like new.
The black plastic pilot jet controls the low speed operation, while the main jet controls high speed running. When the machine's surging, it's the pilot jet that needs to be cleaned. It's sitting under the plastic throttle adjustment screw. Remove the screw and pluck it out to clean.
@29:40 That's a vacuum operated diaphragm type fuel pump.
I came to this video to learn how to test a fuel pump only the find out the instructor had no clue what it even was. I learned nothing
I found a good quick of how dirty, or clean, the fuel supply lines are, is to watch how fast the carb bowl drains. Make sure the fuel switch is ON, and open up the bowl drain screw and watch what kind of flow you have coming out of the drain line. Fuel from the tank should flow freely just by gravity. The most likely cause of no or low flow is the tiny filter in the outlet to the fuel tank. It’s a pain to get to and while you’re there, pull the gas tank and clean the inside thoroughly.
Hi , 93 vs lower octane fuel isn't any better for storage . Buy the ethanol free gas they sell at some gas stations
The Pilot Jet Valve on the back of the carb is plugged,,,thus the surging. easily removed from carb and a #8 wire/file will open the plugged hole and stop the surging. Happened to me too.
What a great video thank you
You got to check there is plastic screw on the top of the carb and it has to have a tiny hole as a breather
Just type idle issue solved for eu2000i on RUclips and there is few videos about it, it helped me
"Surging /hunting when under load" is dust in the finger filter in the output of the tank behind the control panel side, starving for full fuel needs. "Surging at idle" is the very tiny hole down the plastic black idle jet under the black plastic idle stop screw on the exhaust side on the carburetor. Usually very barely dirty in either but thats all it takes. Wet storing is the usually the issue. Great informative vid, good job and informative.
Thanks for the love... Sometimes I wonder if there is so many responses the logistics of any response is overwhelming. Your video reminded me of my Honda eu2000i endeavors educational path. 700 hrs on mine now. Overhauled a blown up one from over oiling in the crankcase. What a mess. Thanks again MC. P.S. Just pops and fires and quits can mean water in carb bowl or low oil shutoff.
The black mystery item may be a fuel pump.
The black part you couldn’t identify was a fuel pump.
In your carb breakdown you didn’t get to the TWO jets. They can get clogged with varnish. The pump can also get trash or water in it but not likely.
How is it running now?
Thanks for the video.
And everyone should remember there are at least two separate jets that have to be cleaned in this carburetor.
I did all of this several times and when I removed the in tank fuel filter it finally works, I say do that first, and see if it runs.
Clean the carburator main jet by removing the bowl..also the idle jet need to be cleaned..!
i have EXACTLY the same problem! didn't run it for a long time and bam.... i cleaned the carb (perfectly) but stil no solution... starting to think its the vacuüm pump?
That thang is the fuel pumpy wumpy.
Hello, thanks for the video. I was given one of these generators from a friend. I learned a lot by ur video. Ty for taking the time. Do u think the 93 octane could be the cause being higher octane could be running lean? I believe the one I have needs a new inverter the electrical portion. With ur birdie I seen how to access it so again I ty for ur time to share. Did u ever figure out the problem???
Howdy! Sorry about the delayed response. The gas was OK. Octane wasn't the problem. I did eventually figure out what the issue was. There is a little screw on the carb that needs to be removed and cleaned out to solve the idle surge. I've attached a link to that video. Best regards, and thanks!
ruclips.net/video/HE73-zly0LM/видео.html
I'm going to make this easy ..
Clean the carb .
Or just buy a clone carb for 25. Is it is really old
I just watched your video and it’s 8-16-2021, I was wondering if you solved problem. I have same generator that idles pretty good but when you put a heavy load on it then it stalls. If you have any suggestions I would love to hear. Thanks
Howdy! What I was looking for is the idle jet on top of the carburetor that's under a little plug. That plugs up and causes the idle surge. It shouldn't affect wot though. I'd try pulling the carb and giving it a good cleaning making sure all the little passages are clear. That usually gets the top end running better. Good luck. Thanks!
Mine does the same, I changed all the gaskets in the carb and nothing changed...
There is a little tiny breather on the top of the carb that gets plugged. If you can find it and rod it out with a tiny drill, that should fix it. Thanks!
Switch out the white part from the other one to see if that makes a difference.
Where ist the airintake to cooling the engine ? All my best
Howdy! Excellent question. I had not thought to look at that before. I made a short video showing what I found. Thanks! ruclips.net/video/W289kzUKwN4/видео.html
I am assuming you found out that piece was a fuel pump.
holy crap all that just to get to the fuel pump wow ... having issues with one of these it doesnt seem to be getting gas from the fuel tank or the pump not sure witch but really dont want to replace now seeing how much you have to tear apart
I like to add that I went for it and found out you DO Not have to tear it completely apart to get to the fuel filter.. I just removed the front cover,unplugged few wires, removed the bolts from the sides, then the fuel tank then i had full access to the rest of it inside. So much simpler then in this video. I think either the on off switch is clogged on mine or the fuel pump itself cause with the the tank bypassing both it runs fine. ran out of time the day i was fooling with it will mess with it more.
Hopefully by now you fixed it. But she'll only comes through the line when you're pulling the Rope basically a mechanical pump in the on position. Fuel comes out at the fuel hook up on the carburetor not that complicated quality generators big major parts don't just go out in them. Not stored properly cat problems start fuel at the carburetor liquid Gas makes it through all the filters right in your carburetor then sits there and turns to farnish drain everything thoroughly run it till it stops. Eliminate these problems in the future good luck. Mr. Honda
Nice😅
I have taken stuff apart just like that.
It would have been nice to look at the manual first to see what everything is before guessing what it is. Also it could use a carb rebuild to get all of the varnished gas residue cleaned out of it.
Clean the carb!
its an in-line filter
I had the same problem and it was a simple 10 min. fix on both of my 2000i generators. The Pilot Jet has a super small hole that was clogged. It is not much bigger than a hair. I used a welder nozzle tip cleaning wire (the smallest one) and was able to clear the hole. They both work like new! Here is a link to another RUclips video showing you how. ruclips.net/video/QdUlhJFHlDU/видео.html
You nailed it, I ended up cutting a bristle off a wire brush to unblock this miniscule jet, fixed it straight away. Screw the black plastic idle screw all the way in counting how many turns before removing it so you know where to reset it after putting the pilot jet back in. This is a Maintenance job you will end up doing repeatedly.
Well after all that waste of time just clean all of your jets in your carburetor and it will run smoothly.
The main jet “ IS NOT THE PROBLEM “ it’s the pilot jet orface is plugged !!!
29:36. It's a bloody fuel pump! Jeez you can even look it up on the parts catalog. didn't you check the diagram before you started taking it apart? obviously not! Still give ya an A for effort
Have you seen the RUclipsr 64ford on this model generator might help.
This guy knows zero about a Honda generator lol
this should fix your problem. No need to tear down the whole machine ruclips.net/video/dLCXb-hg78s/видео.html
O my God all he had to do was clean the carburetor & flush the tank.
That is a LOT of MONEY to be playing with if you don't know what your doing. I bet he went to his local HONDA shop and said HELP as he brings the generator in the shop in a bushel basket. I think he is in for a BIG repair bill at his local HONDA shop $$$
Also never work on your generator with the FUEL CAP OFF. Dirt can re enter the tank and cause more problems.
What a waste of time watching this . This guy has no idea what he’s doing. Took the carb off and did no clean the jets did not remove the bowl . Took all the covers off to look at a fuel pump that he had no idea what he was looking at .the first thing you should have done is pulled carb and disassembled remove float to get to main jet clean with carb cleaner put back together and try to start to see if it runs. Good video on disassembly only . Wish you luck
Oh this was painful to watch. Stabbing at fuel lines and other parts with screwdrivers and guessing at components you are unfamiliar with. So much unnecessary work and you never found the main jet. And no, this carb has nothing in common with your dad's old Harley except a brand name.
You clearly do not have a clue what you are doing. You have made a fool of yourself by putting this video onto RUclips.
