People who watch this all the way through have no idea how lucky they are! Awesome informative video!! Before KZbin, and especially this video, it would take YEARS of hard knock experience to gain the amount of tricks-of-the-trade this man has just shared with you. Especially the carburetor tricks, wow. So like and subscribe. I've been doing small engines for 50+ years but I'm still learning from guys like this! Thanks!!

[@IndRepair]

I appreciate that Don! I have been doing this a long time (not half the time you have though!) but we all still learn every day and if your not learning your either hard headed or don't want to! Thanks for watching!!

[@Honestandtruth]

Exactly right 👍..... without KZbin I Can do very little. But with KZbin videos I Can do Many Fixing things as I choose and able to Understand

WoW, WoW, WoW! 1/13/23 - We are sitting with no power in the house due to tornadoes last night around 6pm in Georgia. Trying to get 9375 to start so we could run the well so we could flush toilets, etc. Hooked up the 3500 Champion for 110v just for lights and fridge. Was breaking down carb on 9375 using a flashlight until 1am and finally gave up on what I was doing. This morning, the internet was up by using 110v so I researched and found your video. With the daylight and your video, broke it all the way down and figured out the float needle was extremely bad, also that damn solenoid needle. Good cleaning and she is up and running. Could be several more days with the damage so showers are nice too. Wish I could send you some cash for the help. You are a life saver.

[@IndRepair]

That is awesome!! Great job getting this done!! There is a thanks button up top next to subscribe you can hit to send some cash if you are in a position to do so. Otherwise a like and subscribe would be payment enough! I am glad to be in a position to be able to have helped you out! Thanks for watching!

[@philliphall5198]

I think it’s best to buy a new carb just for back up and enough tools next to generate to change it out in a hurry

[@IndRepair]

When it's your lifeline always a good idea to have a backup plan!!

Bendiciones desde Cuba, tengo 2 generadores eléctricos , uno de 2 tiempos y otro de 4 tiempos, el de 2 tiempos lleva un año de uso y nunca me a dado batalla pero hace unos días lo puse y se aceleró el solo, tuve que bajarle el voltaje de 133volt a 120volt y así logró estabilidad pero necesita de un buen mantenimiento nunca se lo he dado, sin embargo el generador de 4 tiempos es marca All power y por ser nuevo me a dado una lucha inmensa, pero como buena bestia lo domine por completo y me esta trabajando perfecto.. y le doy gracias a Dios, el pequeño es de 800watts y el grande de 2000watts, pero ahora estoy esperando un generador eléctrico champions de 4375 watts de entrada gas y gasolina, y casualmente ya veo como es el mantenimiento de ese carburador... Saludos desde Cuba.....

[@marcocolon8893]

@Individualized Repair Hello, I followed the instructions you gave in the video to the dot. I was able to make my generator run on gas again. Just as you mentioned, the carburator was filled with gunk from old gas. Wish I could send you the pictures I took from the small parts. Anyway, thanks for an excellent video tutorial. Wish you the best from the wonderful Island of Puerto Rico...👍

Great video! I might have tested it with propane and ran it out of gas and tell em to use propane only. I have a Duromax and its never seen gas. Great explanations and theory on all your videos. Thanks a ton.

@@IndRepair one thing that happend to me is that the gaskets seemed to swell after removal. Should I not have started this without fresh set? I also had them in the carb cleaner…was that bad? Fired it up today after watching and then doing tho!

[@IndRepair]

Usually want to replace them if they are brittle or have bad spots in them. It is possible to reuse in a pinch but we do replace them every time. If it is running well the gaskets sealed ok and it is nothing to worry about

[@philliphall5198]

Every one in Dallas and Forth worth is trying to get there generators running now I got several calls from people but I’m 3 1/2 hours west so I’m telling them how to clean carbs plus asking them to watch your carb cleaning videos

[@IndRepair]

Awesome! Appreciate it!!

[@trcass1]

absolutely fantastic video. my 9375 wouldnt start today. i've never used gas always propane. pulled the plug and that was a pita. as you're screwing it out, the socket gets jammed up at the balve cover, or whatever that is below the spark plug. I'll take what i've seen tonight and try and apply some of it tomorrow. thanks for putting it together. I'm gonna have to bookmark this one. why didn't you use the electric start?

[@IndRepair]

Awesome! How did it go? I'm not sure, I work on a lot that is not electric start so I don't even pay attention to them many times. Thanks for watching!

[@philliphall5198]

It’s crazy they are putting carbon canister on theses untils now Just raise the price more

[@IndRepair]

It's all about the money!!

[@philliphall5198]

@@IndRepairyes Sir, that was there goal

[@robertburnett1970]

If I only run my champion generator on propane, is there any concern of the carburetor getting dirty or is there anything I need to do preventive maintenance? Thanks for any info

[@IndRepair]

If it has never seen gas then likely will never get gummed up unless the propane is a bad quality. Over time propane will leave some deposits but will not be enough to be concerning

[@ADAMTHEGREATNESS]

excellent vidoe, i think it would be easier to buy a new carberator and clean the old when i have time

[@IndRepair]

Definitely easier to buy a new carburetor but sometimes people don't have the cash to do that. Thanks for watching!

[@ADAMTHEGREATNESS]

@@IndRepair I'm not mechanically inclined, I break things more than I fix. lol. I agree. In my case, I could work at Mc'ds here for about 4 hours a buy a new one and spend the week doing what you did in 5 minute video. I do want to say, your video defintitely explains it to a 6 year old. Thanks again.

[@johntate3354]

What size is orings on solenoid and gaskets for bowl and where solenoid goes into.? Great information thanks

[@johntate3354]

Also where can order orings and bowl gasket?

[@IndRepair]

Sorry, do not have the exact engine model from this one to give you the information. We use universal fix gaskets for most of this and Huayi replacements for the rest. Most of these things are so expensive you are better off replacing the carburetor than buying a couple gaskets

[@tommymac3029]

My choice is to use starting fluid. If the engine runs and dies there is a fuel issue. Spark is okay. No start at all, check for spark.

[@IndRepair]

Great method! Thanks for watching!

[@Cenlalowell]

Does starting fluid solve the problem though? Mine will run about 3-5 minutes and then shut off. I have a Westinghouse df9500 and first time experience this

[@IndRepair]

@@Cenlalowell The method he is describing is just meant to diagnose the issue. If runs for a few minutes and then dies check fuel quality, check the petcock and fuel line for restrictions and if there is good fuel and fuel flow perform the carburetor cleaning as described in the video

[@Cenlalowell]

@@IndRepair thanks

[@colbyneilson1966]

To run on propane does the carb to be cleaned out also?

[@IndRepair]

It seems they plug up and will need cleaned if fuwl was left in them and the solenoid is stuck so fuel cannot get to the engine

[@davidcatton3928]

Great Video. I have the same model Champion that is pretty much doing the same thing, and will not fire up at all. It had only run about 10 hours before this happened and only ran on Propane. It will crank & run with starter fluid being sprayed in it. I have to check the low oil (Thanks for that), but other than that could Propane cause the same problem with the Carburetor?

[@IndRepair]

The carburetor controls the fuel supply on both propane and gasoline so it could definitely be the issue you are having if it stays running on starting fluid. Check the fuwl solenoid on the bottom of the carburetor for operation also

[@davidcatton3928]

@@IndRepair Thank you Sir, will do that.

[@hamadeha]

Great video! Is that WD-40 you are spraying onto the parts with the nozzle extension? You mention carb cleaner but i dont see any gloves so im not sure :-)

[@IndRepair]

It is carburetor cleaner

[@colbyneilson1966]

What is the purpose of those green wires you disconnected from the bottom of the carburator? Can you pull start this machine is gas mode without a battery? I have replaced the carburator and still won't run on gas. Propane is fine.

[@IndRepair]

The wires control the solenoid needle which shuts off fuel to the generator when not powered. Some propane is probably able to get past the solenoid need for starting if I had to guess. They should not start without battery switch to on with a good battery

[@NOFBDYBS]

It's always, ALWAYS fuel/carb related.

[@IndRepair]

Most times it sure it! Thanks for watching!

[@RLoose9494]

Yeah the NEW fuel is absolutely terrible

[@andrewbeauchman2995]

I'm still having an issue with the unit not staying running. Any ideas. I feel like it's the low oil sensor. If I unplug the wire from the sensor, will that help diagnose the issue. And it runs for about 10 seconds on either LP or gasoline.

[@IndRepair]

Is the battery fully charged and connected and battery switch on?

[@andrewbeauchman2995]

Yes

[@IndRepair]

Sounds like a fuel supply issue. You can test by seeing if it stays on when spraying carburetor cleaner in the intake. Oil level is ok also?

[@andrewbeauchman2995]

Yes, I cleaned the carb. Tried it on LP and gas. Unplugged the oil sensor. Oil is at proper level. Sprayed carb cleaner while it was running. But it shuts down after about 10 seconds no matter what fuel it is on.

[@USCG.Brennan]

I have a Champion dual fuel 9000 watt and when I push the start toggle, I can hear the starter make a constant noise, but the engine isn't turning over. Is that the solenoid?

[@IndRepair]

It could be a solenoid buzz or a bad starter. I would try jumping the solenoid and sew if starter turns over. If it does you know your solenoid is bad or is not getting good voltage to it for it to start. Also check yo make sure you dont have a bad connection at battery or solenoid

[@USCG.Brennan]

@@IndRepair The starter is spinning, but I'm beginning to wonder if the bendix gear isn't contacting the flywheel. I've pulled starters out of older cars before, is this one any more difficult? And once out do I just regrease the bendix shaft?

[@IndRepair]

Little different but not any more difficult

[@USCG.Brennan]

@@IndRepair Thanks for your responses.....I'll go ahead and pull the starter off. I'll let you know what I find out. Maybe it will help someone else! ;-)

[@IndRepair]

Were you able to get it fixed up?

[@Skbowling2003]

Seem complicated to do this without messing something up at some point. Almost would rather sell my champion 11000 and just buy a new one.

[@IndRepair]

Yeah it has a few steps! Thanks for watching!
