I have had this Generator for about 10 years and it has been used lightly. Did a full service on it, added the filter and was able to remove the carburetor piece without removing the whole unit. Cleaned and fired up. Still has the slight surging, but i can adjust the choke slightly to correct it. Great video, especially the "Small Spring" part.

working on this just last night and ran out of time. Sitting at work today found your video and its great. Thanks for posting.

Wow! We've had this early model generator for almost six years and absolutely no trouble at all. This year before Labor it would only run with 1/2 choke. I should my small engine guy your video and he said Wow! Thank you!

Thanks for the guidance my friend, since I have that same generator model with that same problem, I believed that the problem was the servo motor but after watching your video I will follow your instructions to start repairing. I live in PR during and after Hurricane Maria this generator kept us illuminated during the emergency. It is a good generator. A greeting and thank you very much again.

I actually thought it was the servo motor also. I thought I was going to have to replace the electronics or the motor which would be too expensive so I was quite happy to find a speck of dirt!

timgoihl...Yesterday I started the repair of the carburetor according to your instructions and it is already working as new. Thank you my friend.

Thanks for making this video. I have two of these and one started surging within 10 hours. I thought it was old gas. I will try to clean out the low speed jet. Thanks again.

Thank you, I totally overlooked the idle jet. Running like new again! 👍👍

After a few hours running it was back to it's old antics. This gen is too much work if you ask me.

Another quick note there is a good vid by Champion on how to take the carb out. You take off the fuel nob to get the gas tank out, it's super easy to get to everything unscrewing the knob off first. Was having the same issue. Great to see this tip on fixing it.

Thanks for posting this. I have a pair and one was surging/galloping like that. I didn't know that little clip held in the idle jet. Yes, it can be take out without removing the carb. Remove the top plastic then the tank, remove the servo then the top plate off the carb.. it's right there on top ready to service. I just did it now my generator idles properly again. I had a hard time finding a piece of wire thin enough to poke through the jet but eventually found some. Jets are brass so it should be mentioned that only soft copper wire should be used for that step.

My same generator was acting the exact same way as yours in this video. I’m an automotive tech with 40 years of experience. I knew that it would be a carb problem, but your video saved me all kinds of time and money. No rebuild kit, or total disassembly requited. Went with the tank removal method, since I wanted to clean it out anyway, and pulled and cleared the jet from the top. Put in an in-line filter, one pull, and she’s right as rain. Runs like a champ. Thanks for this video.

Thanks for this. Mine is doing this and I'll try cleaning like you said

Very helpful and thank you! I've got the same issue with a low hours Champion 2000W. Now I know what to do to fix it.

Just want to add that I went ahead and did this last night and it did fix my surging issue. When I pulled out the Pilot Jet, I attempted to clean it with only a strand of wire, which did "seem" to clean it. Put the jet back in, started it and seemed to work for about a minute then back to the surging. Took it back out and cleaned the Pilot Jet again, but this time using Carb Cleaner. The Carb Cleaner worked and it appeared my Pilot Jet was gunked up with varnish. Make sure to use Carb Cleaner on these Jets. For anyone who might be doubting what is in this video, Champion acctually has a help section that describes exactly what is in this video: help.championpowerequipment.com/article/2jEw8sUrlo-cleaning-the-2000-w-inverter-pilot-jet Thanks again for making the video!

Fixed mine perfectly! Thanks

Just had to clean the idle jet again. I guess it sat too long with out being used. Thanks again bro.

Thanks, your video helped me too!! I cleaned out the idle jet (the idle jet on mine is plastic??), it was definitely clogged, put everything back together (but not without dropping countless screws and sockets down into the genny cavity, arghh!), and it started right up. My fuel smells slightly stale, tomorrow I will drain that and refill with fresh.

Buen día, que tipo de aceite usa?

Thank you for saving me a buck

CPE tech support told me that adding a fuel filter would constitute a modification that would invalidate the warranty on my 2500 W inverter genset which began to hunt and cutout at less than 30 hours and one month old. They told me that the carb might be bad and that it was back ordered two months out. This model requires that you dismantle half of the case to remove the carb but I did it and then cleaned the carb. Runs great...for about 4 or 5 minutes. Manual says that the fuel valve may be dirty and it is acting like its is switched off or nearly so. There are no instructions about cleaning the valve anywhere. I am starting to think that the single integrated valve/choke/kill switch is not such a good thing. Never had any problem with my Hondas with separate fuel c/o valves.

@timgoihl

You could do what I term, "a consumer managed warranty..." Buy another generator and either swap out the carb and then return this one as defective, or just return your other one saying it doesn't run right under the new receipt. Like a lemon law, which is what you got!

This fixed mine. Still a small sputter might be the spark plug which isn't 5/8 or 3/4

An excellent video, thanks. What do you think of the build quality of these champion units? They're not all that common across the water here in the UK, and am seriously considering purchasing one. I like the way that champion have designed the fuel system so that a pump is not required. Most other generators of this style seem to be fitted with a crappy little vacuum driven fuel pump that's bound to go wrong at some point! These look like nice generators. What are your thoughts? :)

The nice thing about inverter type generators is that type can run at low speed (meaning quiet) for light loads, but it can then run at full rpm (louder) for heavier loads. But an inverter type has a lot of power electronics to create the AC, which is a failure point. The carb is clearly 'cheap' and the lack of an inline fuel filter says cheap too. This generator is light and works great for camping, mobile power tools jobs, etc. I think if you have some basic mechanical skills (could do the job I did), then you would be ok. For a home-backup situation, I think I'd go with a true 3600 rpm generator.

Awesome video. I bought this same inverter today for 40 bucks. It runs exactly like yours did in the beginning. I'm going to follow your steps to clean it and add a filter. I do have one question though. What do you think about running rotella 15w40? I run it in my dirtbike, 4wheeler and boats inboard. I'm going to try it out when I change it. I'll let you know if it blows it up. Rotella is really good oil and it's cheap. I think you're supposed to change it ever 100 hours in this thing so I think itll be a good choice.

Sounds like you got a great deal! Believe it or not, I'm not really an engine guy... just someone who likes to tinker and fix stuff. You may want to do a full tear-down of the carb to clean the float bowl and other carb ports like I did and maybe even clean/flush the fuel tank while you have it off. Did you get the manual for the generator? You can download it here: www.championpowerequipment.com/product-manuals 15W40 is not a suggested oil. Full Synthetic 5W-30 is rated for all temps from -20 to 110F. Considering the oil is not changed often, why not go with the best you can buy? It only uses 0.4 qt. Protect your investment :) ! On the recommendation of my Stihl dealer, I even run non-ethanol fuel in most of my small engines (esp those that sit around) to keep out water - the alcohol attracts water and who wants that inside an engine? Yes, the fuel costs more, but given the small amount of fuel they use, it doesn't cost much. Watch out for that little servo spring and good luck with the repair!

Mahalo! My Champion 2000 only runs on 'Echo'? Do you think this might be the same problem? It always surged but only slightly. Thanks again!

@timgoihl

You mean no rpm change when you flip the (Eco)nomy switch? I would say you have a different problem. Could be wiring, the switch itself, the electronics, or the little servo motor. You could disassemble, unplug and re-plug each connector (in case there is some contact corrosion), test the Eco switch with a continuity meter, and do a visual of the wiring. Your surging at low idle might be the idle jet, but I don't think it would be related to the full speed mode. You could post a video of what it does!! Also check this video: kzread.info/dash/bejne/ZmWrubmhc9m8daw.html The LED module seems to control some of the speed control... In other comment Tasha Teeling said: @NEEMA BORJI Mine had old gas in it and it was causing it to run poorly and the power would shut off even though it would run. Oil smelled like gas. Serviced the oil, plug, rebuilt the carb and now it's okay.

It seems the generator may be missing by design an in line fuel filter. Cheap and easy to install and likely worth doing to prevent dirt from getting into the carb

Others have said there's a filter in the shut-off valve assembly. I haven't taken it apart to see yet, but if there is, it must not be very good if dirt is getting it to everybody's carburetor.

There probably is a separate fuel filter connected in the tank to the fuel line. If you remove the line from the tank it should drop out or you can pull it off the tank.

@timgoihl

I don't think so. Just that prestrainer when filling. The shut-off valve is located right on the bottom of the tank. No place for a filter. And given the amount of debris that gets into the carb, clearly the filtering system is inadequate.

I've heard that. What is the micron rating on that filter? Given the number of people that have 'Carb' problems with this generator, I don't think it is adequate for the job. I still stand by adding the external 75 micron in-line filter, unless you want to tear-down your carb every few months....

If the machine is fairly new just turn your idle screw in a turn.

Actually there’s another fuel filter where the petcock attaches to the tank. Have to pull the petcock off, and it’s in the downspout of the tank.

Emptied out gas at end of summer, stored in dry, heated garage all winter. Put fresh gas in and now it won’t start at all. I’ll never buy champion again.

I don't think Champion has a problem so much as some Champion customers have a problem. You cannot reliably store gas in ANY machine for great lengths of time without asking for trouble. This little generator has a fuel drain screw to empty all gas from the fuel system prior to storage. Plus use medium or premium grade fuel to rule out ethanol in all small motors, plus add Stabil to the gas for long term storage. I do this for three generators, a snow blower, a lawn mower, a large boat motor, a pressure washer and several string mowers and in 50 years I've never had a problem of any kind even with gas stored over a full year. Proper maintenance procedures are vital for storage
