Thanks for watching. This Wen generator wasn't used for awhile and unfortunately when that happens they usually don't start. The problem was very common and pretty easily fixed.

@5:13 did it for me! I removed the needle jet and stuck a safety pin through the hole until I could see through it. Finally fixed a generator that hasn’t ran in over 5 years. Thanks!!!
no problem
Nice fix, 👍👍. I make it a point to run my Honda genset once a month, letting the fuel run out and also draining the carb with the drain plug just to be sure it’s dry. I use a stabilizer called K100 which i find works great, it removes any water in the fuel. I use this stabilizer in all my equipment and never had an
issue. Thanks for the vid! Stay safe.
Thank you Tman NC for the information. I'll have to look into K100.
Well done as always.
I drain the bowl, and try to run the tank out, but I can’t always get it completely empty.
Besides, it’s hurricane season, I crank mine every couple of months, too
That's what I would do too. How big is your generator?
I use a stick to prop it up on one side. No issues so far and nothing is wasted.
Nice. I like the double-nut stud removing trick. Stabilized gas.
Thanks and I always suggest stabilizing gas for any equipment
With my propane generator I just remove the tank and store it as empty. My gas generator I am still trying to make it run consistently. I had it running really good for a bout 5 minutes then it just quit as if it was out of gas. Removed carb again and see no blockages. I am thinking I have a bad low oil level sensor but I think I still have spark. Gonna have to revisit this once again. Your fix was perfect. Great job. Thanks for sharing.
Thank you D Butler for the comment. Let me of you get it working.
Just before it begins to quit,try loosen the gas cap,it might not be venting,bad gas cap.
@@jerrysoutherland662 Ok. Thanks Will do
Some new generators have a fuel shutoff solenoid from the low oil sensor rather than spark shutoff. I watched several propane conversion videos that all have fuel shutoff wiring from the low oil sensor.
@@stephenmcgowan8572 could you send me a link to those videos?
That thing is awesome i’m trying to find more weed eaters to work on KEEP UP THE GOOD CONTENT
thank you Jack Grundy
My 8750 Predator generator has a 5 gallon tank. It is stored full with 93 octane premium gas with 10 gallons on stand by. It gets started every few months and let to run for 15 minutes under load. Carburetor is always run dry when finished. In the fall I drain the fuel tank and put it in my truck and fill it up with fresh 93. It's a heck of a generator and works great.
wow you really are ready and knowledgeable about your generator. Thanks for the comment I appreciate it.
I had to use it for 37 hours straight once. Ending up draining the fuel from my tractor and anything else I could find to keep it going. After that I became much more prepared. It's a strange site at night when everything is dark with no electricity and your house is lit up and looks like nothing happened. The money saved in frozen food almost covered the cost of the generator. Here is a tip, wire it into to your breaker box.
@@dwwd156 you are absolutely correct about the wiring.
Thanks for the excellent tip on removing the left carburetor stud, that’s a big help. I’m sure I would’ve been fighting with the linkages and never even thought of that! I store mine the same way you do, I drain the tank and run the carb dry. I also like to change the oil while the engine is still hot. Great video!
Thanks mjg263 for the comment I really do appreciate it
Great work! This looks pretty similar to the United Power unit I picked up recently. 😊
nice, does it work?
@@HomeGaragechannel not yet, had good fuel, spark, and air when I got it. But the compression felt very light in the pull start. I ordered a compression tester online and just got it in recently. It only has 35PSI. 😲 So I'm gonna pull the head apart and see what that all looks like. On the bright side I didn't pay much for it and it had a full tank of good gas. 😂 Just drained it and topped up the tank on my Yamaha. We have an ice storm coming in apparently!
let me know what you find out.
Good one mate nice and simple
Luckily. It could have been worse.
Always full to the brim with fuel+stabilizer. Power outages are frequent here in our area so the generator is always ready to keep the house powered minus a/c. It’s 15 years old with 400 hours and has run for days in a row with no problems. 🤞
thank you Jason Souliere
Just worked on a similar engine on a compactor plate, its a right pain getting the carb off the studs .
They sure make it difficult. Thank you Alan Lake for the comment I appreciate it
My ood Onan 2.5 doesn't have it's own tank and I take the hose out of the jug nd run it dry. The Coleman 5k has an extended run nylon tank but I have a 'T' in the line and an extra shut off valve below it so I can drain the tank and run the engine dry at the same time. So far it's started every time when needed. Good fix and I've seen Wen make some tough stuff! BLESSINGS!
thank you Lewie McNeely .
@@HomeGaragechannel U 2!
Great video, thank you.
Glad you liked it!
Very clear and informative
Glad it was helpful!
I also like to empty them when I can. If not I always run the carb dry. Also I usually clean out the idle low speed jet when I have the carb out on the bench. Thanks for the video. By the way when someone purchases a generator, I am curious why they would not get one with a minimum of 4000 watts so you could run a furnace, lights, refrigerator, heating system, etc. I recommend to my customers to get at least a 8000 watt generator. Thanks.
It was only $99. It might have been a budget issue.
I would love to get a 8000 watt generator if I were in my late 40s , but its just me an my wife now an we are both in our late 60s , a 1800 watt portable on wheels is just right for us plus I have a Harbor Freight Storm cat 800 watt that runs amazing!!! So we are good to go for a outages.You still make a good point though!!!!
My first go to is the carb. Ether usually tells a lot and is quick. Remove the bowl and spray carb cleaner has so far never failed in getting it going enough for the occasion.
Thank you for sharing your experience I appreciate it
yeah, mine too. check fuel flow to the carb 90% of the issues. the other 10% is cleaning the carb. at least in my experiences!
I love that stuff. I've bought several used generators, cleaned the carbs, and resold them. Along the way, I've wished for a small hole in the air filter box, behind the filter, so I could directly spray in ether, aka "cheater spray". But I don't want to do that to a generator I'd sell. And for my own, I'd rather take good care and never need ether.
Awesome thanks 👍
You bet!
Nice video.
Thanks!
Ram-board floor protective covering is great for making gaskets.
I'll have to keep that in mind.
Fixed me! Thanks
Glad to help
Gracias por sus videos
no problema
You are a lifesaver! Thanks so much!!
No problem!
I usually just test it every 3 months just so i know everything works on my generator and then run it with the fuel valve off. At the end of the year around october or so is when i put some fuel stabilizer in the tank. I also run the generator with the stabilized fuel just to do a basic clean out of the carb before i store it for the winter.
Excellent technique. What kind of generator is it? Thanks for the comment I appreciate it.
@@HomeGaragechannel generac 3250. But it has to get a powerhead swap.
@@evilredBoris I've never had to replace the power head. Good luck with it.
Well that was easy. And that's why adding an in-line fuel filter is a good idea, folks. +1 for Home Garage making another video happen.
Thank you for the comment 999thenewman. I would buy a bag of in-line filters and put them on all the 4 cycle equipment but if I did that I wouldn't have anything to fix and film!!
@Cory Gill im glad you found the humor in it. Thanks for the comment I appreciate it
Home Garage I have a question if a trimmer runs rich will there be black burned oil around the exhaust pipe
@@flix8743 Yes, along with a sooty dark spark plug, and it will respond to full throttle slowly.
999thenewman well my trimmer is 2 months old but it has oil around the exhaust but it goes full throttle easy and very fast
I don't have a generator at the moment at least, we have had a new 132/11kV substation commissioned in 2014 which has only been knocked out once due to a Wild storm.
Ever since then,out power supply has been a lot better.
Having the fuel tank mounted so it instructs spark plug access is a bit silly !
That's what I thought when I saw it.
I was recently given one that essentially looks the same as this, the spring around the throttle to choke arm is broken, any idea what it’s called or where I might get a replacement? It’s surging like yours was with the fuel off so maybe I have fuel delivery issue somewhere, and at first startup it produces only 50v, after 10 minutes of running it starts to jump around and eventually gets to about 230.
do you mean the spring that can be seen at 4:25? if so that's the return spring for the throttle lever. If yours is surging you need to clear the pilot jet, and if you don't want to do that, A replacement carb is very affordable.
welding tip files are very good
Yes they are
all my power equipment is run on to empty then I drain what might be left in carb.
Best option in my mind. Thank you David Anderson for the comment
@@alext8828 it empties it to the point that what little remains will evaporate.
I've got 1200 W Champion generator. I close the fuel valve and let it starve. Then I drain the tank. I have been using this method since 2011 and never had a problem starting it.
Nice method
same problem same fix on my firman 7552. would run on propane but not gas. check the solenoid mounted under the carburetor as well.
thank you Larry Blinn.
God that worked added it to my router
"Spark tester". Isn't that a misnomer? Doesn't it 'just' test the ignition system up to but not including the spark plug? If you have a defective spark plug wouldn't this give a false positive? Asking because I'm wondering if the primitive method of laying the plug on the engine would show you the actual spark (in dim light)? Thanks!
The spark tester is a misnomer is it only tests if the ignition module is working. And no, laying the spark plug on the engine doesn't test whether or not the plug will work while its under pressure. So I would just replace the plug anyway if theres any doubt after testing for a working ignition system.
the problem is portable generators have a gas tank inches from the sparkplug.....spark testing over gas fumes and gas wet generator would definately set your hair on fire!!
I have a Champion generator and I just had the exact same problem!
it's a very common problem. thank you Dwain Holloway.
Leave the tank empty my friend its OK for us people up here in Scotland our fuel is different.👍👍
Nice. Thank you William Duncan for the comment
Before storing the gen, run it out of gas and drain the float bowl. Then mix some gas with a shot of transmission fluid and run it again. Then redrain the float bowl. Now store it with a tag that describes what you did and the date you did it.
thank you Mascotal
nice
Thank you Randy Scott.
I store portable like that either empty or at minimum I will run the carb bowl dry even if it is treated fuel.
Thanks Nashguy207 for the comment I appreciate it
I leave mine for with stabilizer And the reason why is so the rubber parents don’t dry out from just cold weather and then finding out to get stock and then gas pours out of the carburetor because I’ve had that happen
It will take some time for rubber to break down. Ethanol is much worse though
well done learned a lot today. I do have a question and maybe you can help. i have a 7kva gen and it start 1st turn bud after about 30 t0 45 min it dies and smell like its overheating... Any help would be appreciated
you didn't mention if it would start back up after it stops?
@@HomeGaragechannel no... Not starting after it died. Next morning then it starts with no problem
ah. I see, next that happens, I would open the gas cap, for a minute, then close it, and then try starting it.
@@HomeGaragechannel 100% ill try that and let you know. Thanks
Before removing the carburetor, wouldn't it have been a good idea to try squirting some starter fluid in the carb and then attempting to start it?
I apologize, I did do that, but off camer,. I should have shown it, in the video as well.
@@HomeGaragechannel Thanks.
no problem
to get the correct reading on that dipstick you have to screw it all the way back down and then unscrew it again?
wen 1800 watt generator, owners manual, page 8, under generator preparation, step 1 "adding Oil", number 3, "To check the oil level, wipe the dipstick with a clean rag. Insert the dipstick into
the oil fill opening without screwing it in. Remove the dipstick to check the oil mark"
Empty. I turn mine back on at the start of the Huricane season. I actually remove the spark plug and spray wd40 to lube the cylinder walls to help with that first start up.
thats sounds like a great way to keep wear down. thanks for the comment
I have a brand new out of the box WEN 4750 that won’t start/run. What can I do ?
this model might have a Low Oil shut off, how much oil was put into the engine?
Everything i own with motor i will not let Just sit for long periods of time. I will from time to time start them up run them around let em run for about 10 minutes and them put them back up for another couple months. No more then 2 months at time. If i dont do this i already know im wrecking them/causing them to have problems. Its good to fire them up let them run for 10 minutes. Simple fix for surging engine is seafoam. Keeps carb cleaned out. I use GY-6 Full synthetic for my Honda Gen. I dont play around. God gives nice things so i take care of them.
very good way of thinking. Thank you GodisMyLight
@@HomeGaragechannel - you didn’t check for 60 hertz under load, adjusting gov idle screw or spring. Can you point me in the right direction on adjusting governor? I’ve got one that I need to work out, gov not doing anything to hold 60hz. Removed all slack on gov position rod, will try adding slight slack to see if that does it.
oohhhoooo a grateful man you are!! im sure g-d does nice things for you!!
Hi have same generator, the output supposed to be 110v but why is my generator output is 240v?
some are wired that way. There should be a sticker the generator stating what the output is supposed to be.
I run stableliser in all my stuff all year long
Me too. Thanks for the comment I appreciate it
What is the emissions tube for
Its to recirculation the engine blowby from the valve cover back into the engine intake.
What type of oil is best for generator
I would suggest 10w-30, But always follow what your manual says
If I had a generator i would add in a fuel stabilizer to the good fuel and run it for s couple of minutes then run it dry to avoid gumming up the carburator jets etc and keep an eye on the spark plug too
That is a great way to avoid generator problems. Thanks for the comment Patrick Stapleton.
@@HomeGaragechannel my pleasure mate cheers from Australia and it,s currently our Spring Season atm and perfectly ideal for mowing too
@@Patrick4959 nice. What are Temps like right now?
Can you make the brush cutter videos
I working on it
What type of oil do you use ?
car oil, 10w-30.
Do you have any social media , i want sent a photo , i did restoration my generator and assembly camshaft and cranshaft but i have problem camshaft my generator no have any signal to join cranshaft , can you help me about that problem
sure, send your questions and pics to homegaragemail@gmail.com
Hello can i ask how i fix my generator the gasoline mixing with the oil in the engine?
is sounds like the Gasoline is leaking into the engine thru the carb, I would replace the carb.
I have a generator that runs but doesn’t generate power. Is the generator fixable or is it just a pile of scrap? thanks
it's still fixable. I would look up your particular brand online for power problems and more than likely, someone has already come up with the fix for it.
@@HomeGaragechannel Thanks you.👍👩🔧
So I have a 110lb generator it has no gas tank and no cage. I thought it would never run because I have just gotten into 4-stroke and so I used my 2-stroke knowledge and shot some fuel down the carb and it ran for a solid 4 seconds so now I need a gas tank
nice, at least you know it works
@@HomeGaragechannel yep
Looks to be the same carb as mine, recon I've got the same problem !! 🤔
I hope you can get it working.
@@HomeGaragechannel .. I've had the carb off but didn't realise the bottom bowl came off, I thought it was threaded & tried unscrewing it but it was very tight. Think I'll just hit it with a rubber hammer & see if it breaks the seal !!
give it a shot
How do I get the tank filter out at the value shutoff
Can I just pull it out from the bottom
it's all one assembly just unscrew the fuel shut off valve out of the bottom of the tank .
It's very similar to Generac power generator... Both made in China
Thanks for the information I didn't know that.
I keep my generator empty. But i do start it once or twice per year and then let it run dry
Thank you for the comment I appreciate it
I got a diesel one that runs on oil once in awhile I got to hit it with starter fluid.
i've always wanted a diesel generator. did you buy yours new?
@@HomeGaragechannel yes got it 5years ago got it on sale it's great cause you can run it on used oil
@@adammosher5818 thats my goal then. Thanks for the comment I appreciate it
@@65csx83 have no idea what you are saying.but I run mine on used motor oil and use starting fluid when it has trouble starting
Fixing most new equipment has become a real PIA. No wonder considering the hourly repair rate, it becomes cost effective to just buy new.
You are absolutely correct
I have a dewalt portable generator. It has 275 hours on it. It starts with one pill but shuts off after about 30 mins of use. This just started at about 265 hours. I use 93 gas. I’m a truck driver and I use it to power my mini split AC/Heater. Also to run my microwave and tv. I NEVER have both the AC & microwave going at the same time. And yes the generator is producing enough power to run the AC. It was working just fine last week. Any help is MUCH appreciated. I’ve cleaned the spark resistor thing several times. The spark plug looks good. I drained the fuel chamber on the carburetor.
just for my information, have you checked to Oil to make sure it's not low? after that, I believe you have a fuel flow issue. This can be from a combination of things, such as a gas cap that's not venting enough air, a fuel line that beginning to swell, and causing reduced fuel flow, and the last, it could be a needle seat that's also swelling and causing less fuel to flow to the carb.
@@HomeGaragechannel oil seems to be okay. I changed it a couple weeks ago. But yes the level looks okay. I’m not much of a mechanic, but I’m not ignorant to engines. I’m guessing that the needle thing is internal carburetor correct?
@@HomeGaragechannel should I leave the gas cap off maybe?
yes it is, replacing the carb, would be the easiest way to fix it, rather than taking the carb apart.
no, because you'll loose some fuel, as the engine is running and that would be quite messy.
Sea foam, its really good stuff. But i drain my carb for storage.
Great tip!
@@HomeGaragechannel Champion 4550 started right up after 1.5 years, same gas with 40ml of Sea foam, full tank. Only about twelve hours of use on the Gen.
3 words "Inline Fuel filters "
Thanks for the comment
1 VERY important factor to consider. ........ I cant name not even one Generator ,1400.00 price range or less that has an inline fuel fiilter. And I believe, its because they dont want it to last years & years reliably. Almost every generator , the first issue that will arise is having to do with the carb. most will just sell it off or deal with the issue by rebilding it or replacing the carb. But overall usually the first issue and often Only issue will be the carb is acting up due to debrees and buildup.
They know this, but ya dont see an inline fuel filter on them.
I don't remember if there was one on here, but there probably wasn't
great tip!! $1 filter = $500 genrator saved
And what happens when the problem is that there is no electricity for the spark plug...could it be the coil?
that, or the on/off switch, or the low oil sensor
I have the same generator but it won't stay running??
replace the carb.
To a fair extent, work on half a dozen of these it is like having worked on 60 of them.
I
d rather take the time to clean a carb an get it back to the customer quicker than
buying a new carb.
you make a good point.
I could use a video on how to change the oil on this generator
let me see what I can do.
I always store mine empty!
Thanks for the comment I appreciate it
Mines surging like mad, I dismantled the carb completely and cleaned it thoroughly but it's still surging and only runs smooth on half choke
The fuel line might be swelling internally restricting fuel flow, or the screen inside the tank, right where it leaves the tank might be clogged with varnish.
@@HomeGaragechannel
Thanks for the reply, I've cleaned out the filter in the tank, but you're right about the fuel lines, I'll check them next, it's a suitcase generator, do you think it could be a faulty diaphragm pump
could you tell me the make and model number, that way I see what it looks like. I'll then be able to answer your diaphragm question.
@@HomeGaragechannel
Aww thanks, it's a honda eu2000i and it's done less than 100 hours, but it was left for about a year with a tank full of fuel in that time I only started it up about 4 times
thanks for the information, so the carb on this honda eu2000i doesn't have diaphragm, but a bowl and float, just like their lawn mowers.ruclips.net/video/xrxDsecBpTA/видео.html
I store me generators dry, drain the fuel tank, run the carburetor dry, and then before i store it i change the oil, blow out the air filter and airbox, whip it down and put it away
Excellent
I keep mine with fuel stabilizer
thank you Small engine repair, Lawn care
@@HomeGaragechannel I am doing yards and fixing tools this summer
@@joshuaschannel1335 nice, do you have many yards to do?
When you do another repair can you show your face
Some day
If he was a good small engine serviceman, he would have cleaned the whole carb., before putting it back together. What was shown was the high speed jet being un-clogged, and if it's clogged there's a good 50% chance the small jet is clogged as well, as well as the fuel tunes, the fuel flows through inside the carb. It's best to clean all parts and tunnels in a carb, before putting the carb together, and back on the engine. Had I done the servicing, I would have started mainly with the carb., before checking the spark plug, but a small shot of starting fluid, and a few turn overs, would have told me whether engine had spark or not, without buying a spark plug checker, and added extra work getting the plug out. If engine fired up with that shot of starting fluid, you know it's a carb. issue, not electrical. Would have saved time, in getting to root cause of issue of not running. 90% of engine not starting, or running poorly problems is carburetor issues. The engine surging (revving up and down), is caused by a dirty low speed jet. Problem is, he failed to clean the whole carb., the first time round, which he should have done. Like I said, if you take a carb apart, clean the whole thing, and clean it well, before putting it back together, and mounting it to engine.
thanks Wayne Davies, there are a couple more generator videos on here that you need to watch. there are some on some blowers, that I need more advice on as well. I'm sure you'll have so great advice to give.
I think you would have been better off first if there's a drain screw drain the carburetor see if there's fuel there if there is fuel there then turn the fuel valve on to see if it flows through...... you are lucky and your oil there is no gas it appears so..... your float is either stuck up or it is stuck down...... and then you remove the carburetor
I think you're right.
What Is Wrong With The Generator?
He said it in the beginning. It hasn’t been used in a while, so more than likely it isn’t starting because of the carburetor. I have yet to watch the video, but I’m assuming so.
The main jet in the carb was clogged.
@@Anonymouso283 you are absolutely correct
@@JaneT-vv3tv yes sir
You really want Far and Beyond to remove that spark plug it could have been removed without the tanks being removed
for filming
Lmao oh i understanding now
Starting a gen, with a load on it; > >> IS A NO-NO....never STOP a gen, with a load on it. Always run gens, for 2 minutes after removing a load !
Google on why......
hey thanks
Yeah --- play it safe -- leave the tank empty ...
me too.
chances are some1 just shut off engine w switch, not thinking gas is still in carb and after
a few months, the jets and orifices in carb get clogged bigtime+ running in a possible
dusty area can make it run rich due to less air to engine. If not run for some time, the
residual field can be lost and can't build up voltage, then u flash the rotor (field) with a car
battery or lawn tractor or bike battery. push button circuit breakers do go bad.
thank you for the information
how to store gas ---
If gas isn't there -- there can be no dirty gas after not using it for a lengthy time ... so store your generator with no gas in it ... problem solved ...
that's what I do.
