Thanks for watching. This generator is practically new but it has a very strange problem. The problem is that it runs perfectly fine in choke but not at all, off choke. The problem was related to the carburetor of course but its something I've never seen before.

The nozzle was the the problem !! I love it when a troubleshooting video actually fixes the issue, Thank you
Glad it helped!
That nozzle as you called it, is known as the high speed jet. In this video, the guy should have cleaned all routes within the carb, not just the high speed jet. There was no mention about the low speed jet that's in every carb on the market. They need cleaning as well, and might as well do it the same time you clean the high speed one, so you don't get surging in engine.
Man you saved me a ton of money and worry. Jet was clogged up completely bread tie cleared it up running like new. I changed gas and oil before I found your video. But now it's ready for the ice storm coming in tonight and tomorrow

Glad I could help, and it looks like you did a great job getting it running too.
My exact generator. Had this problem for years. Going to try your fix this Fall. Thanks!
Good luck!
Oh man!! Am so glad I found your video. Turns out it's the exact unit I have AND the same problem. Thanks so much!!
No problem and thanks for the comment
@@INSIDEHOUSEGARAGE Just a follow up. I was able to do this procedure this morning. It worked!!! Reason I'm excited about this fix is I'm in Texas and you probably heard about the problems we've all had here with the freeze. Our power went out during the rolling outages from the power company, then a water pipe busted (luckily in a exterior wall and not in the ceiling). I had started my generator just about a month earlier but with temps in the low 20s, with no lights, heat, or water.... OF COURSE, when I needed it the most, had no luck starting it. Pretty sure I flooded it and sure the choke situation was the problem. That jet was semi clogged, like you showed, and after cleaning and re-assembly, it ran like new. 20/20 hindsight. Should have searched a month ago for this problem. Anyway, thanks again for sharing this video. So many times UA-cam has saved me lots of costs.
@@joeanddianeroberts1101 great work Joseph Roberts. I'm glad it worked out for you.
just fixed my generator with the help of your video. Thanks for posting this
No problem
I followed this to fix my generator and it works like new now, ty!!!
no problem.
I sent this video to my son with a very similar generator and he fixed it just as fast. He said the spring also fell out and he had to chase it down but remembered your video to look for it. Good Job. 👍
yes that pesky spring can really get you
Worked for me on my Hobart Champion 145 welder!!!
Thanks. 👍🏻👍🏻
no problem and thank you
I'm surprised, simply cleaning the hole fixed the entire issue! Nice work!
Its really that simple sometimes
That nozzle/hole as you called it, is known as the high speed jet. In this video, the guy should have also cleaned all routes within the carb, not just the high speed jet. There was no mention about the low speed jet that's in every carburetor on the market. They need cleaning as well, and might as well do it at the same time you clean the high speed one, so you don't get surging in engine.
A quick fix thank you for the clip.
No problem and thank you Patrick Boyd
Replace generator with snowblower,chainsaw,lawnmower etc…………thank you for the help👍🏻👍🏻👍🏻👍🏻
Glad to help
Thank you so very much for this video my generator would run on choke and when you put it to run it would make a sputter noise but wouldn't cut off it was still right so now I'm going to take a loose my carburetor maybe it's the same problem thank you very much
no problem Johnny Harris
@@INSIDEHOUSEGARAGE I tried to do what you done it didn't work so I tried some seafoam and it worked
nice work
Dang, you solved my problem without knowing it! I thought the choke was on but turns out I'm an idiot and didn't know which symbol meant what. At 1:17 you can see the run/choke symbols clearl. I thought my generator was busted fro the box.
glad to be of help!
Easy fix. Best type.
I'm glad you agree with me. Thank you Luke Harrison
Thank you...i knew this but forgot. Hey, sometimes...if there's enough room you can remove float bowl bottom bowl..without removing the carburetor and linkages and use a carb-spray into that jet and then a metal needle or pin to clean out that brass jet from below...and then just one bowl-bolt back on and you're up and running.
you are absolutely correct, it just doesn't make for good filming is all.
Thank you that worked for me.
You're welcome!
Thank you very much.
no problem
Thank you for the video
Thanks for watching!
As far as the choke handle goes you do not have to force it off simply turn it so that the notch comes through the notch in the plate. If you look at 2:27 you can see the plate notch and the little bent plastic piece you forced with the screw driver. If you had tried in the run position it would have came right out.
I have had my 8250/5500 generator since 2009 and have had to pm it many times over the years! I forced my choke handle the first few times before I noticed the notch myself. I would say after having to rebuild my carburetor twice over the years that running it empty does not guaranty it will start next time. I agree 100% it seems like it would but I will challenge you to run it dry remove carb bowl and see what comes out.
I will try this fix on my genny thanks!
No problem
Nice video
thank you Malik motor mac.
A can of seafoam did the same thing for me simply follow the directions on the can and run it in choke til it it runs normally took me longer to mix the fuel/seafoam than it did to clean itself out stuff is amazing 😉
Great tip!
Obviously junk in the fuel can that ended up in the carb. Dissoluble crud is a simple fix with Sea Foam but dead bug parts or leaf bits not-so-much. You can't know which "flavor" you have unless you tear the carb down.
This is the biggest reason to use a screened funnel for ALL gas into small engines.
That is my exact generator. Wouldn't start at all, so I took the carb apart and sprayed carb cleaner everywhere. Now it only runs on choke. I guess I'll take it off again and clean the jet. Hopefully that works!!
that is usually the problem. good luck
@@INSIDEHOUSEGARAGE That fixed it! Thanks a lot.
no problem.
Thanks. This helped me immensely. I had the exact same problem. Only thing that got me was on the B&S 6000 portable generator there was NO spring inside, despite being very careful, it just didn't have one. But all 15 out of 16 air holes, and the jet nozzle was clogged. I'm surprised it even ran. Also echoing the notch on the handle comment below.
that's interesting
Some have a spring, while others don't. It will run without the spring in both cases.
Haven't watched the video yet, but just by going by what the Title says, tells me carb issues. Running on choke means not getting the right amount of fuel mixture, possibly running too lean., or carb. jets needs cleaning badly. I picked up a generator a couple of weeks ago, that had the same issue. I both cleaned the carb out properly, and reset the fuel mixture, and it runs great now. Starts on either first, or second pull. Now I'll watch the video, and see if I am correct in what I wrote above. I'll bet I am right.
thank you Wayne Davies
What tool did you use at the 3:47 mark to push the jet down to pop out from the bottom?
How do I put the jet back on?
Is it pushed down from the top?
Can it be cleaned out with a wire without popping it out?
Appreciate any help!
Thanks!
I used a torx screwdriver, but anything that will fit will work to push the jet out.
You simply put it back in the hole, gravity keeps it in position.
Yes push down from the top to put it back in.
Yes you could clean it without taking it out but it might get clogged again, thats why I take it out.
no problem.
Never herd of a E6 socket before, i guess its like a male torx bit, good fix, but not keen on all the plastic bits in the carb .
Yes they are also needed if you work on VW cars. Me too. Plastics are meant to break
a 4mm socket will work too...
@@jacriel4416 yep
I have an Honda EU2200 with about 2 hours on the engine. Only run non-ethanol+stabil. Also run the tank and carb completely dry. Plan on taking it camping for several days this summer, hope it starts right up.
I hope, when do you think you might do a test run?
Thank you! My Generac Wheelhouse 5500 generator seems to run smoother when backed off full choke 1 or 2 notches. If I run it on the "run" setting it seems to run rougher. I have sprayed choke cleaner around the gaskets but it made no difference on how it runs. Any suggestions?
sure, if you have the time, I'd start looking inside the carb. If not, just replace it with a quality part.
That was an easy fix♡
Super easy.
Preventive maintenance -Startron will keep the gumming from happening over periods of down time. I run my generator every month for 15-20 min. Under a load like a light or compressor.
thank you for sharing that
Have an ice storm coming. Mine is doing the same exact thing. Any harm in leaving like that and fixing it later? At least it’s running right now. Don’t want to make matters worse, but also don’t want to mess something up running it like that if I shouldn’t. Looking forward to hearing!
I really don't know. It's one thing to have it run on choke with no load however I'm not sure what will happen of you put a substantial load on it. Hopefully you won't need to use it.
Currently in Texas, right there with you on not wanting to touch it and lose any use when it's most needed. Have you had any issues running it on choke for the time being?
i have the troy bilt 8250 with B&S engine, mine was doing the same thing, during recent power outage in KY. It ran fine on full choke, so I loaded it up with two freezers and ran it 4 hours on full choke with no trouble at all...now today, I ran onto this vid after getting power back and thanks to INSIDE HOUSE GARAGE it is fixed and running great without choke!!!
@@jacriel4416 thanks for the comment I appreciate it
The problem is Briggs carbs do not run good with ethanol additive in fuel. Per the B&S people they never modified their carbs to adjust for ethanol additives. That’s what I finally pulled that info from one of their techs, 4 years ago. The engine only had 45 minutes on it. I now drive into town to get ethanol free gas. Expensive!
And here’s the kicker…. They wouldn’t cover it under warranty. They sent a new carb but I was not allowed to install it. I had to have the carb sent to a professional and I had to pay for labor! I’ll never EVER buy ANYTHING that has a B&S engine. Honda is the best I’ve found to date…
thank you BAD KARMA. Ethanol in gas is definitely a sticky issue
@@INSIDEHOUSEGARAGE
It was just an incident…
No problem…
i have craftsman 3600 watt it does almost the same thing it will start in choke but as i move towards
run it will still run halfway between choke and run but the closer i get to run it starts sputtering than shuts of. any thoughts on this. Thank You much
sure, service the carb, and also check the float and needle
Like a newbie, I didn't catch which way the float goes back into the carb. Skinny end first, then seat with screwdriver?
never took the float off.
Good morning, I have the same generator as your. I cranked it up and switched it to the ON position. It ran for a bout 15 seconds and stop and also lock the choke. I am now not able to pull the choke because it's locked. Can you make a video on how to fix the locked choke?
you'll have to take off the air filter and the base. Your choke flap might be stuck because of the base hitting it.
Hello sir idk if you answer questions but if so I have a predator 4000 watt generator I replaced the carburetor gaskets new gas changed oil had to running perfect it ran in hot weather probably about 96°F then I noticed it started to leak gas from carburetor now it will only run on choke when I try to turn if off it boggs out any help would be great thank you
interesting, first what I would do, would be to turn off the fuel valve, disconnect the line from the carb, and put it not a cup, and then open the valve to see what kind of flow you're getting from the tank, to the carb. If that's good, then there might be a clog that made it from the tank to the carb and it needs to cleaned.
I always use ethanol free fuel and run it dry after each use. It always starts on the first pull.
Nice. I appreciate it if it starts after any pulls so long as it starts. Thanks for the comment I appreciate it
I gave brand new chinese carburetor with this issue was made for 420cc .. ill try getting jet hole slightly bigger
I have a generac pressure washer that has the same problem but the carb is fully clear to my testing can you help?
sure, but I need more information so I can help you. what's the model number of the pressure washer? And when you cleaned the carb did you clear the Fuel Jet? And if so how did you clear it? thanks
Is the carb almost the same for a husky 5000 watts ? Mine also runs on choke
No I don't believe so
You don't have to remove the studs to get the carb off if the frame isnt in the way. I have a pressure washer that won't run unless you're thumb is almost completely blocking the air flow coming in the carb with the air filter housing off!
thanks
Could a blocked spark arrestor cause the choke only problem as well?
I have a champion 46595 3000 watt, cleaned the carb and I have the same issue. I also removed and cleaned the fuel shut off valve and still the same thing...?
the spark arrestor would have to be 100% closed off, and that's doubtful. Even If it was 90% blocked, it would still start, and run although not well.
@@INSIDEHOUSEGARAGE
Thanks for the reply!
I actually verified that the spark arrestor is clear after I asked but thanks again!
I have a new carb on the way so we'll see what happens...
no problem
@@INSIDEHOUSEGARAGE
New carb...same issue
I tried spraying carb cleaner around the carb while running hoping I'd encounter some change in how it runs but nothing...?
Does it matter if my generator is brand new? Mine is doing this but this is the first it's had fuel and has ever been started.
I would check and make sure that the switch is in the "on" position, that the choke was ON, and that fuel was getting to the carb. After that it's more diagnostics to find out what the problem is.
❤
I have this same model of generator, it is a powerhouse and I truly appreciate the american build...but man do I hate this style of carburetor, B&S went super weird when compared to the Honda style which are soo much easier to fix in the field, on the back of a truck..I'm scared to take this particular style apart, I don't trust it. The float / nozzle / main jet setup from a Honda style is so much easier to manage.
I know right, The first time it took It apart, I couldn't believe it. thank you gv280z
Well, I watched the video, and I was correct, but don't just clean the main jet. Blow out all the other routes the fuel uses to operate properly as well. The jet cleaned in video was the high speed jet, and there was no mention of the low speed jet, being cleaned, nor the routes the fuel takes inside the carb, for low speed idle. NOTE: ... If your going to open up a carb to clean the main high speed jet, clean, and blow out all other routes inside the carb. as well, where the fuel takes through the carb. to operate properly. Then it's not a waste of time, in taking carb off a second time, if cleaning wasn't done well enough and still ran bad.
yes doing a deeper would have been beneficial but in this case, it wasn't needed.
My customer power generator same problem but after cleaning crab but problem is not solved any other problem sir
I would suggest replacing the carb. If that doesn't work then I would inspect the engine for an issue.
I replaced my carb with a new one and still have the running on choke issue. Must be the mixing valve/screw which I’ll be checking on tonight.
good luck with it
I run mine once a month for 15 minutes. Started right away on a blackout last month and ran for hours.
very nice!
What would be the problem if i have to prime it for it to start and keep priming it for it to run
the carb is not working, and priming it is the only way the engine is getting fuel to run. Look at the carb and see if there's a problem with it.
Mine too.
I have that problem with running on choke, with a carb I borrowed from another generator. That generator ran with out choke
it happens from time to time.
Do you fix and sell?
No not all of them.
I’m afraid cleaning the carb didn’t do anything, neither did buying an entire new carb, or unclogging the fuel cap, nothing worked. What’s wrong with it?!
can you confirm that fuel is making into the carb bowl. If so, then the problem is the carb. have you checked for spark and compression?
Well that was easy.
Easy is my middle name. Wish they could all be so simple.
I don't know why but I had to watch that thing run until it ran out of gas then I was just like huh
nice, I appreciate your time Andy Hollister.
I store all my small engines with 99 octane race fuel. Lasts a long time and has no ethanol in it.
nice , you shouldn't have any problems then
@@INSIDEHOUSEGARAGE but your video has helped me sort out 2 engines for the guy next door. LOL! Thank you!
@@IROCKID no problem. Besides you did the work
My fuel bowl was full of fuel when i took it off. Is that an issue?
it's supposed to be, that's the fuel, that's going to be delivered to the engine. Is there a problem with the generator?
@@INSIDEHOUSEGARAGE yours was empty when you unscrewed the bowl. Mine was full. I get it to start on choke but it pulses a few times and then shuts off.
I see, that makes sense, take the easy route ,and replace the carb that's what I usually suggest to people
Just keep it dry no gas .
That's the best way for me too. Thank you Pete Froud
I did all of this and got me a new carb and still ran on choke?
The carb wasn't the problem on yours, The fuel pickup inside the tank that goes out of thank could be your problem. It has a built in mess screen the will varnish over and limit the amount of Fuel the flows to your carb.
@@INSIDEHOUSEGARAGE thanks, I did clean out the tank. I guess bi need to replace the screen.
@@jeffnations6649 yes, the varnish is very touch to clean off the screen, no problem
@@INSIDEHOUSEGARAGE hi there again. I did what you said about the fuel tank. I hook up a separate clear tank I have for testing ethanol free gas and filter and still runs with the choke on. I guess I will clean the new carb again, but everything looks super clean and lights thru all the orifices. I have a mikuni VM 22 I will thinking about putting on it.
@@jeffnations6649 that's strange.
4:50 negative
You know, 90% of all small engine issues, are caused by bad/poor fuel mixture, or dirty carbs. I have worked on thousands of small engines, from lawnmowers to outboard motors, and they all have the same fuel issues in most cases, when they run poorly
did you notice if I didn't something else wrong? I haven't looked at this video in some time.
How the hell new carb does this
Mine's doing this right out of the box piece of s*** product
that's a shame.
