Update video for people that still need help th-cam.com/video/mE39dlHgO30/w-d-xo.html
my generator is running but it won't stay running
I purchased an after-market carb on eBay for my Westinghouse WH7000EC because the old carb was leaking gas. The old carb was not surging it ran fine. The new carb is surging, I watched your video and did everything you did, drained old gas, and installed new fresh gas 93 octane. Took the plastic screw and its 2 mating plastic parts out, used a wire carb brush, and flushed the carb with carb cleaner. I reinstalled everything only to find the surging did not get corrected. What do you suggest I do next?
Great job...I've been trying all I could for two months on a CAT 3600..no luck.. runs and surges.... wish this mechanic lived next door..I'm 97 years old and can't lift it to get it back to the store for service... any one in Naples Florida who can do this???
I bought my Honda 2000 used (barely) and it was surging on eco. On a whim I added some sea foam. I’m sold on it now. Ran it thru & have had 10 years of service since without even a hiccup.
You can turn the idle screw "IN" before you remove it counting the turns it takes to seat it. Then after reinstalling it turn it all the way in till it seats then open it the same amount of turns it took to seat it before you removed it and it should be almost exactly where it was. Thanks for the video.
Yes good tip
I was about to say the same thing but you said better ...
That's assuming there's an idle screw...new stuff all sucks
why would you need to do that, the generator never idle
It sets the throttle position for starting. But this also works for other small engines such as lawn mowers and chain saws.

DANG! Generac with less than 70hrs total use, always surged and got tired and found this video. Fixed in 15 mins 😩. You got my like and subscription. 👏🏻
Well thank you for that. Glad you are up and running
Thank you from South Africa. I did your repair and I'm pleased to say that my Generator now runs like brand new.
In my case. Surging Honda GX 390 on a generator was surging only under 1/2 tank of gas. Tried solving it with new or even no gas cap, new fuel hoses, fuel filter, petcock, flushed gas tank, new Genuine Honda carb and even used aviation fuel. Still it would starve out near 1/4 tank and would only run while spraying starting fluid in the carb.
Surging = Fuel Starvation, especially with less than half tank of fuel in my case, even when it was new. A generator runs at high speeds all the time requiring the highest of volume of fuel in the line at all times.
Generators are designed to be low profile and an inherent flaw is that the fuel tank is (TOO LOW) just slightly above the carb fuel inlet for gravity feed through a hose. At high speeds and especially with little fuel in the tank causes a weak flow to the fuel inlet causing starvation/surging.
MY SOLUTION:
I discovered that by raising the entire fuel tank by 8" gave me MUCH better fuel flow down to the carb and the surging went away even with almost no fuel left in the tank. You can definitely see the difference (before and after) with a see-thru clear fuel filter which should always be at least 1/2 full during operation on a high speed motor/generator.
Another mistake I made was storing Ethanol fuel for more than one season in my shed. The stuff goes bad and causes havoc on small engines. Periodically check the color of the stored fuel in a glass jar. It should be clear. If it is golden/urine colored, DONT USE IT in a small engine.. Car engines don't seem to have a problem with the aged fuel. I had about 20 gallons of yellow colored fuel and added a few gallons at a time to an almost full tank of gas in my car and it burned it with no problem.
I hope this helps somebody as I almost gave up and it cost me $ and lots of time, but I won and learned a valuable lesson that nobody ever suggested to try.
Saved me a lot of time (was preparing to take carb off) and got my generator running like new! Thanks!
I'm glad I work for you. This chick doesn't work 100% of the time, but most of the time it should
Thank you for the information on where the high speed jet is located. Put on a brand new carburetor and it was still surging. Drilled out the jet with the next size up drill bit and now runs smooth. I liked the old days when these mixture adjustments were out in the open and not hidden and fixed.
I had the same problem with a lawnmower with bad gas. I got to get one of those pumps since it's a good price. Seems like those jets get clogged up fast even on mowers. I got to do that with my tractor cause it surges a little. Oh that sounds good. Thanks to you and your videos I am confident to take the carb apart. Thank you Andrew.
Did exactly what was shown in the video and my generator is now running. Had to clean out the carb twice but it worked. Thank you!
Glad you machine is up and running my guy
you are the man! I've dismantled and cleaned the carb jets multiple times in the past but this time I was stumped bc it was still surging.. you saved me so much aggravation with an easy fix... thank you👍🏼+1
Did the same as you and still surging somewhat. Now I cant wait to try this. I did not know that pilot screw has 3 holes, I cleaned 2, and the bottom hole was plugged but I thought that was by design, realize now I have to remove and clean that gunk stuck in there.
My Man! This saved me a huge headache. Gennys running like a top now. This worked for me.
Thank you so much, I live in Florida and because of Ian, needed my gen running, this fixed my issue, I am really grateful Thank you.
Thank you for watching I hope you and your family are ok
good video. watched after I spent 2 hours searching for that damn pilot jet. had to take it off completely and clean all the passages whit a thin iron wire. now it's works like new
Glad it worked out
Saved my work day the other day!! Thank you and you made it so simple 👍🏽👍🏽👍🏽👍🏽👍🏽
Glad it helped!
This video just saved me! Generator was surging and I couldn’t figure it out. Watched this and now she’s purring.
Hell yeah
I have a Troy Bilt 2410 snow blower and this cured the hunting issue I had after cleaning the mail jet. Thank you very much.
Glad it worked my guy
Had my champion 4500 open fram start surging at work....... Found this video and it cleared it right up. I just disconnected my spark plug and did the above repair. I did not drain the fuel.
Thank you, you just saved me a big repair bill, plus transport.
I have a generator just like yours, that stopped running after only 10 hours of operation.
I could not even find a repair shop willing to take it in, the only shop in the area listed for warranty repairs did not do that anymore..
Did not even know it was called "surging", until last week. A common problem, apparently.
Then I found this clip, I did what you said, and now it runs perfectly. Thank You!
I am glad you got your machine running like new or in your case like it is supposed to
Riding mower with Briggs 19HP searching for idle mainly under load. I forgot about this trick, so I'm going in.
bought the fuel stick on your advice. liked. Thanks
Thank you for watching and helping the channel
Make sure your generator has an in-line fuel filter in the hose between the tank and carb. If not you can probably get one at Lowes or Home Depot. They're usually easy to install. Because the carburetor jets are so small, they clog up easily so having the gas filtered can save a lot of work. Most manufacturers don't include a gasoline filter. Why? Maybe they'll save .25 cents and make more money on service work?
Most of these engines have a filter in the tank side of the fuel cock sticking up into the gas tank.
Just want to say thanks for the video! I actually had to drill out the vertical hole but once I got it cleared out, it ran like a champ.
That is a good trick too
WORKED OUT PERFECTLY , THANKS FOR SHARING , MY GENERATOR STARTED SURGING @ ABOUT 3 HOURS OF BREAK IN SO I WAS PISSED OF THINKING I HAD TO CLEAN THE ENTIRE CARBURETOR , EXCELLENT VIDEO KEEP THEM COMING !
Glad to hear
Thanks for this!! Not mechanically minded at all and my generator is now running smooooth
Good to hear
Thank you for this video. Much appreciated.
Thank you for watching
I just went through a hurricane in Florida central Florida Polk county Florida to be exact. Lost 50% of my roof. I would just like to say I was watching some TH-cam videos and this video popped up it just so happen to be the exact same generator that I was using and the same problem I really appreciate it tomorrow morning I’m going to go out and see if I can fix it the generator work but all it did for about 12 hours every day with surge up and down up and down. It did work and it did run it just surged. Videos like this are very helpful I really appreciate them thank you very much and thank you for all your help ❤
I'm really sorry you lost in the hurricane. I feel bad for the people who survived the hurricane. My thoughts and prayers go out to you and I hope you get your generator running
@repairGang: If your generator does not have the auto idle, sometimes called economy mode, then turning the “idle” screw will have no effect on idle adjustment. It didn’t look like your generator has the auto idle feature, but I may be wrong as I couldn’t see the whole front panel. The screw you were turning, on a non auto idle is to hold the jet (the small black tube you were cleaning) in the carburetor.
Good job! Always screw your idle air screw in until it stops and count the turns so it can be put back the same way, you don't want to run them too lean.
Idle screw has NOTHING to do with air fuel mixture!! It is an IDLE SCREW. You should ALWAYS set min and max RPM with an induction tach according to manufacture spec.
Your right there
Yeah I feel that I so use to lawnmowers with same carbs I just say to adjust it
@@meyou3353 slow idle is a moot point on a generator, and high idle you set with a multimeter
@@romak4756 you are wrong
This worked for my Firman generator, thank you!
Firman is getting really good actually to be honest I like working on them now
Yep! Been cleaning pilot jets for years. Works every tim
Nicely done. Works for a Honda en2500 as well!
Thank you for a great video. I have the exact Westinghouse gen and exact problem and now fixed.
Glad it helped
You are the best :D , same issue was with new generator. So saved me time and long road to service!
Glad you got your thing back up and running. The video helped you
Thank you 🙂
This explains why my push motor mower did that sound so often ha hah 😂
I had just perservered while mowing.
I know what to look for now 👍
Thanks from Slam Bang fishing lodge west coast of Vancouver island Kyuquot sound we specialize in good times
fishing is always a good time
It worked for me. The man is amazing. ‼️
Glad it helped
Thanks for sharing that trick- on all other than westing house 4cyc small engines- turn the screw in bottom of float bowl- and that will fix a rough idle most every time- i think all the jets need tweeking from time to time do to dirt and grime settleing in those little carb and jet area- or at leiste older model units- That 9500 looks perfect size unit- i could probley run my 8' electric base heater in a power out senario.
The 5 back from bottom worked for me. Luckily a easy adjustment
This video helped me fix my surge on my firman 3650 thanks!
thats awesome
I had the very same issue on my 10K watt generator. Watched your video and did exactly what you demonstrated and it is up and running just like new. Thank you for sharing this!
Thank you glad it helped yeah they get bad when they sit a min
@@RepairGang i had the same problem with my generator reving up and down but mine did it after it got clean up just like you did , before it dint start up at all and was puring out gas whenever i try to start pulling the rope , any reason why any help whould be great
I would take off whole carburetor and clean it then you knocked dirt loose
@@RepairGang i will try
Yo if you need a walk through email me pictures
Thanks! This worked out perfectly. I used it on my Powerstroke 5000. Don't know what caused it because I only ran it twice in 3 years. I replaced the fuel added a cleaner and preservative and followed your instruction and smooth running. Thanks again.
Great tip thank you! Worked like a charm.
Awesome 😎
Great information ...... Good Education ..... Thanks....
I will be doing mine today thank you great video
Hope it helps
Thank you buddy! I cleaned the entire carb but missed that Damn pin hole at the bottom of the idle jet! Watch this before bed went back to the shop 5 mins later she’s running like a champ!
Hell yeah
Thank you 🙏 😂😂😂
I just fixed mine right now
Gracias 🙏
PERFECT. WORKED FOR ME MAN. THANKS 👍
Super glad I work for you my man
The Generac 8000e has the same idle screw and mine is surging exactly like that and when it’s under load, will stall. Going to try this next. Great vid!
Thank you
Thanks, this did the job!
I've often seen the surging due to water in the fuel bowl temporarily shutting off fuel flow into the main jet. Remove the bottom fuel bowl center screw, drop the bowl, clean-out the bowl and reassemble. Lucas Ethanol gasoline treatment works great, green bottle/color, add to regular gas. Nice job on the video, quick and to the point.
That could work
I've never been fond of Stabil fuel treatment.
Good tip, thanks!
Worked perfect. Thank you
You're welcome!
Didn't have a brush but did the carb cleaner trick took 3 trys but it worked
Sweet
Thank you so much my generator stopped working mid night during busy hours and I bought some cleaner spray and that was the problem
Glad I could help
Put some SEA FOAM in your gas tanks . Wonderful stuff , eliminates water , stabilizes the gas and cleans gum out of carbs . Once got an OLD Snow blower , badly neglected . Poured SEA FOAM into a dry gas tank to pull it thrue the carb and it started and ran...on only SEAFOAM ! Years later , that motor is still running trouble free ! Ontario Canada .
I do like sea foam only because and engine can run on it but can't on any other stabilizer
Thank you !
Worked for me, thanks. But I had to remove the control panel, air intake and carb to get at the jet on my Honda EG2800I. (the air intake and carb were held together with the same set of bolts to the manifold).
I always use a set of hair bits and drill the main jets out. Especially on Briggs and Stratton engines. They are almost always undersized and surge. Most older generators don't have that pilot jet setup and you have to remove the bowl to properly clean it.
Yes correct 💯 thank you for watching
Exactly what the problem was, Thanks! ;)
I have the very same issue with My RYOBI 6500 Generator. Surging / Rough operating. I never realized that when I got it 3 years ago (acquired in a scramble at Home Depot after losing power for days from Eiasis Storm in NY 8/2020) that the gas I purchased should be Satbilized [Stab-Il]. I should have read the manual more thorughly. As soon as I got it up and running for about an hour, the pwer came on!! I have test run it only periodically since. When electric went out the other day, the generator started up with difficulty ( a lot of pulls) and ran with a surging. THX for this video. I will clean the carb as described and hope that does it!! BTW, that battery operated pump / Siphon does NOT get all the gas out of the tank. it leaves a remnant as he siphon cannot suck up from about 1/4 " from the bottom.
Just did what was described ... Had to do it 2X, I did have a thin wire brush ,but used a very small metal wire. That seemed to do the Trick. Learned my lesson about using Old Gas. I had no idea. I do now. Bought STAB-IL for the new gas I purchased. Do I add STAB-IL to the Generators gas tank? or just to the gas in the storage conatainer?
So helpful thank you worked great
Awesome
Worked for me!
Thanks for this video
Glad it helped
Great video man thank you! 🤙🏼
Thank you
@@RepairGang your are very welcome 🤠
Help me alot thank you
Thank you for watching
That screw you took out is your JET SET SCREW. Unless you have an inverter generatot, this screw sets your rpm of your engine. The rpm speed of the engine determines the cycles per second (hertz or frequency) of your generator head. In the US we have 60 hz, Europe is 50 hz. If you do not have a frequency meter you should start by turning this screw in all the way while counting the turns to get back to a ball rpm speed when you reinstall it.
Yep
Great video
thank it work for me ..i have same problem 👍👍👍 luckily i see your video...tq man....
Glad to hear that
Thanks!!!
For anyone who found theirselves in the situation, if you intend to store it for "next time" be sure to run fuel with Stabil added for a few minutes, then empty the tank, run it untjl it stalls, then drain the float bowl. Lastly after the engine cools remove the spark plug, squirt a tablespoon or so of 2 stroke oil in the cylinder, crank a bit, then replace the plug. Now when you try to get it going next time, it should work.
Sadly my familys own generator has been neglected SO MUCH, but the thing runs anytime we need it to...old old fuel, rarely used ect. I fix them at my job and see how they get bad real fast. 95% of it is old gas.
Great tip! but I dont like fuel stabilizers lol I just say drain it all out leave it bone dry and it be good to go when ready
old gas is a pain in the ass lol
The 2 stroke oil will foul your plug. Use stabil fogging oil.... other than that spot on.
@@meyou3353 YOUR wrong
Thank you for sharing
Thank you for watching
I have found that even cleaning carb after removing it and take the float and needle valves out and the main jet too that it still will surge after cleaning all that. I ultimately had to drill out the main jet a 0.001 or .002 because it was running too lean. If anyone is too scared to do that then try ethanol free gas first because that would naturally enrich the mixture with the same volume of fuel used. I found that helped in my case before drilling the jet to be able to use regular unleaded with ethanol mixed in. Oh I forgot that you need to check the float level too ! If it’s too low then it runs lean also. I fixed my uncle’s brand new Pontiac in 1977 with a hesitation problem due to lean flow. His mechanic didn’t want to mess with it and the dealer couldn’t figure it out I believe. I found the float was set too low and that wasn’t enough to stop the hesitation so I was able to adjust the metering rod slightly higher as well. The car accelerated like it should with zero hesitation after that!
I've had a backup generator since the hurricanes of 2004 tried to move my FL home to Kansas. I've had to rely on it only twice since, but every year before hurricane season begins, I fill several gas cans, adding some Stabilizer and Marvel Mystery oil to the cans. I use "only" non-ethanol fuel. I'll put about a quart of fuel in the "empty" tank and run it until the engine quits, never leaving fuel in the tank. After nearly 20 years of mostly garage storage, it will start on 1-2 pulls every time. Any fuel not used by the end of hurricane season is emptied into my vehicles. No problems whatsoever.
Hell yeah
Why Marvel Mystery oil?
Good upper cylinder lubricant and cleaner.@@jimcicchino8705
I pulled my carb apart 3 times thinking the problem was the jet inside the float bowl. I never knew what that plastic bit was until i watched this video. I have 2 other generators that don't have that plastic bit so i didn't think it was anything important. I fixed my other 2 generators by removing the float bowl and cleaning the jet inside and assumed the same had to be done to this one. But having no luck i then found your video and now its up and running again. Thank you
I'm so glad this helped you my guy. Many more videos coming
Yes never knew the other jet on the side my water pumps are doing this clean carb but I’m gonna try this one soon
Mine is doing the same … works most things like grinder drill but won’t entertain the small welding set … it has stood a long time will try new fuel … fingers crossed all your help appreciated🇬🇧
I hope it works it's more then likely the carburetor
Nice, Thanks!
Thank you
Friendly suggestion: stop dropping the pump or gas cap on the ground. It can pick up a few grains of sand or dirt and then get dropped right into the gas can or tank.
Noted 😂
I've got the 7500/9500 with 2900 hrs on it lol, dont know their lifespan, on 2nd set of brushes, "fuel pump" is out so i just gravity feed it, its been little rough lately, i shall do this! Most small carbs do that crap cause cheap gas with ethanol. They wanted me to take it, all 200+lbs of it to idk...been a mechanic 40yrs. One review guy said he got parts under warranty, ill see.
Thanks
Welcome
I’m going to try this and if it works I will tell you how it worked 👍
Sweet let me know
nice info. thanks.
Thank you
Always use premium gasoline or Non Ethanol gasoline in combination with Stabil gasoline stabilizer. The ethanol in these gasoline gum up the jets and carb. It’s best to clean the carburetor bowl out while you’re at it. All the gum from the gasoline sits in there.
I'm ok with non ethanol but I would never recommend stabilizer maybe seafoam but probably not just don't keep gas in machine drain and store
@@RepairGang I disagree. Always use stabilized fuel in small engines. Always
I have had bad experience but it's anecdotal evidence. I'm pretty sure if a customer followed the instructions it probably be a good idea, but that's okay. We're allowed to disagree
@@RepairGang hi I'm a waterfowl hunter that uses a 2 cycle outboard.
Since I started using stabilizer I've had zero carb problems.
That is anecdotal
just run the gen out of gas to shut it down no need for premium or to add anything its worked for 30 years heck i use a gen 4 hours a week every week to power my water pump the gen is a 1998 model sold in 1999 and still purrs like a kitten ive opened the carb 1 time in 23 years 1 time
Watched another video in that the guy turned the black screw at pilot jet on carb all the way in noting how many turns it took to hit the end. Then after cleaning out , putting back he unscrewed it out again the same amount of turns it usually between 4-6 full turns , Good video 🕵️👍
thank you
Fun fact. Generators aren't designed to idle. The idle screw goes in far enough to hold the pilot jet, but it shouldn't be installed far enough to contact the throttle plate cam. Otherwise it will interfere with proper operation
I put new fuel in my champion 4500 brand new to and it did this. i will look to see if mine has this and try it.
952. Closing in on i1K!
Let's go baby I'm stoked you almost 3k
the hi speed mixture screw is what I found that will correct a "hunting engine"
Good job. I just hate the noise these things are making. Why can't they put a decent muffler on them. Those inverter ones are a LOT quieter.
Awesome..couldnt figure out why my brand new Westinghouse did this. Do I need to set the idle screw in a certain way or just screw it in?
good video! after you add fresh fuel...ad some sea foam...fuel additive...
Nooooo
Add a little gum out to new fuel to complete cleaning the carburetor.
Good video
Thanks for the visit
Please make sure when readjusting the idke you use a milti meter and reset voltage and frequency to the propper ranges....your kooking fir 120 volts and 60 hertz for american electricity
Check your surge spring and clean your carb.
Word to the wise. Don't use ethanol gas in anything that will set for a long time, as it will separate from the gas and foul your carburetor.
Use ethanol free gas instead. Also if you have a tank valve on the machine, turn it off and let the engine run dry of gas to shut it off to drain gas out off carburetor then shut off the off switch. This will help keep the carburetor clean for future use. If you are using 2 stroke engines be sure to drain the 2 stroke fuel after use, as it will gum up carburetor if stored for too long.
Sweet
My honda genny was surging found the tiny govner spring had come off put it back all good.
Good to hear glad you got it running
I got myself a new Dual fuel Carburetor yesterday and it was a nightmare to install (because the frame was in the way) after removing the engine from the frame , installing new carb back on the frame . My generator wont run, neither on LPG or Petrol, it starts but cut off within a minute the sound was like yours at the beginning . Petrol is new and so is the carburetor
I found an easy solution to all the gasoline problems. I converted my generator to run on propane!
Propane is actually a really clean energy source. You just lose a little bit of wattage
Thanks for teaching me about that idler screw but, first five minutes of your running will be the fuel that’s in your carburetor bowl! Would’ve been better to have during that out as well…
I own exact generator! If I am going to store. I will pull the ethanol out of the gas and treat it first. Videos on the "tube"
I have a brand new duromax running rough on propane and gas. Non ethanol. If I hold the auto choke lever further open further than it’s auto position it goes away. Is there an adjustment for that?
Worked as shown tha nks forest
Glad to hear
