Good job! Funny story. I 've worked on everything from small engine stuff thru heavy equipment and trucks. One day I went to start my mower in the Spring, just like this, and no go. So I did exactly what you did. Took the carb apart, put it back together, and voila!! Started right up. I let it run on its own for a minute. Tied a rag around the handle so it wouldn't shut down. No biggie. In the middle of a big yard. I turned around and the mower was ON FIRE!!😵🔥🔥Went over, untied the rag, the mower stopped and I put out the fire. WTF?! Nothing got seriously burned. Not even the rubber tubing. Turns out there was a fine crack in the fuel line and the gas reached the muffler and poof!! Learned my lesson. Always inspect all the lines and don't leave it running on its own. Take nothing for granted. That's when trouble happens. Cheers.
Wow you're lucky it didn't explode. I plan on replacing the fuel lines on all of my equipment this year due to all my equipment being over 10 years old and my lawn mower is about 25 years old but it still runs great.
@@bretthibbs6083 Don't know that it would have exploded. But ya never know. But by all appearances, at first, all was fine. But it being an older model, and moving the carb and stressing the fuel line, it formed a hairline crack that was out of sight. Fuel line must have been brittle. But I lived to tell the tale.😄 Cheers.👍
A mower deck is supposed to have a drain hole to let oil or gas or water drip straight down away. Not all of them have that anymore. They also pinch the plug wire at the cooling fins and the top housing. Are they deliberately trying to cause fuel related problems? Hmmm. Safety is important. But these things aren't made in our country anymore. We have to do it for our own equipment once we have it.
@@dannylinc6247 Mine had a weep hole. It just went poof!! I never had that happen with ANY piece of equipment I ever worked on over 50 years of working on like everything. I've made mistakes here and there, but was sure everything was fine. But turns out the gas line was a bit brittle and a hairline crack formed on the bottom I didn't see, or smell gas. But then, I did work on the carb so there was a residual smell of gas around. One thing we have to remember is gas gives off vapors you can't see that lay close to the ground and will ignite. I guess the muffler threw a spark or got hot enough to ignite the fuel. It all happened in about 2 minutes total. I got it running and just walked away for about 30 seconds. Turned around and it was ablaze!!😵😄 It was no biggie but it was a surprise. Anyway, long time ago. And I take nothing for granted since that time. I went on to cut the lawn many times thereafter. And, I did change the fuel line. Cheers.
@@justincase2281 seems like you handled it well. I had a free good quality mower given to us at a shop. The old guy there said, don't use it. And if you use it anyway, and I'm not here, don't use it when the grass is dry. He was busy with other things. Well, needless to say, the grass was a foot tall before you could say, "uff da". I used that mower, it wasn't dry outside yet. I looked down after a few passes and it was a nice machine, cut well. Felt easy to push But the muffler was cherry red and burning like somebody heated it with oxy-acetylene. Good thing there was no external fuel leak. It ran ok, seemed to, but it was putting out unburned fuel. I shut that sucker off. Like you did. I told him about it next time he was there. He said, "you don't listen, now you get to figure it out." I didn't run it for more than a couple minutes after that, at a time. He gave it away, so I suppose the thing had a heavy float.
For me I put gas preservative in the fuel in the fall. In spring tilt lawn mower so spark plug is down and pull engine cord slowly. This lubes the engine rings and restores loss of compression due to oil having left rings over winter. Put some fresh gas in the tank. Follow normal starting proceedures. Usually starts on first or second pull or usual effort. Works on most small engines that are stored for many months at a time. The rings dry out and you loose compression, this process restores it. For car or other engines some times pull spark plug and put a little oil in the cylinder works same way.
Also start them up every month or two and let them run 10-20 minutes let the engine get to full operating temperature. we do that with both mowers and the motorcycle. We even take the rider out and run the blades on high cut setting to
Hi Don , don’t know you agree with me or not , when season end , run the lawnmower until the carburetor emptied , then fill with transmission fluid , next season , emptied the transmission fluid out , then fill with fresh gasoline , start the engine, it would be heavy smoke comes out for roughly 20 seconds , I have been doing it for 15 years , the same machine yet to let me down ( yet to have to clean the carburetor) have a great Sunday !
Thanks for the tip my man! Quick question, what am I filling with tranny fluid - the dismantled carburetor? Surely not the mowers tank? I hope this comment gets bumped up or you make a video cos this is how you actually prevent the EXACT same thing from happening next season!
The Sears Mower we were given for not running has a primer bulb but it connects to nothing? Probably the issue with this mower ..it has a plastic carb so gotta see if a hose is missing there
In the past I've always just used cheap gas and I don't think I ever used Stabil in my equipment til my brother told me to use it and even then I always had trouble starting my lawn equipment in the spring then I started to use the non ethanol fuel in my equipment probably close to 10 years now and never have a problem starting even after sitting for nearly 7 or 8 months through the winter.
Cleaned my 140cc engine's carb, but the idle was surging after that. Cleaned the idle jet. Better, but still surges a bit. Maybe the idle is a bit low... We shall see. It's brand new, but was stored over-winter with some gas in it... so the takeaway is always to empty the mower of gas when storing away.
Ok now that was an extremely helpful video. Thanks for taking the time I've learned allot from this channel. I could actually spend a good hour just asking questions about chainsaws especially the newer models.
I have a 20 year old Craftsman 4.5 horsepower push mower, every fall before I put it up I run the gas out and it seems like it starts better come spring. I think condensation builds up moisture in the garage.
With “minor plugged” jets (ran last year), I’ve had good luck leaving carbs installed on the machine, removing the bowl and working a welding tip cleaner up the jet and then blowing compressed air up through the jet and putting the bowl back on. It usually takes just a few minutes.
Good video ! here in the U.S. the "EPA" would have a "hissy fit" seeing someone use a cutting torch tip cleaner on the jets. Honda makes a tip cleaner that doesn't enlarge the orifices. Just straight wire. Works well !
everytime i take apart a lawnmower i clean the gas tank too ..just for whatever reason if the carb is plugged it could be debris coming from teh gastank...btu anyways i used to sell old broken down mowers to guy rather than scrap them and hed buy them for 5 bucks.. and ia sked him how he knew and such how to fix them and he told 9 times out of ten its the carberator thats teh problem..tehn he moved away and i kept getting mowers so i decided to see on youtube how to fix them and ive gotten rpetty good at it and its a neat and fun little hobby.. and since then i havent had to pay for a mower or snowblower ..i just buy old ones and fix them:) saves aot fo money and keeps me busy its a good thing:)
I had the same thing this year fixed last year n ran great went to start and no fireing or anything spayed carb cleaner in the the carb and spark plug hole and nothing adjusted the ignition coil and boom fired and on 2nd pull and now fires on 1st pull and just did this 3 days ago
Thanks for the video Don. I look after all my equipment and have learned a lot from you. Touch wood, my equipment starts on the first pull. My neighbour wants me to look at her mower because it is doing this exact same thing and i have been bragging to her about watching your videos.
Hmmm, I have a very similar carb on my little toro snow thrower. That carb gets "dirty" at the drop of a hat, even though I physically drain it at the end of the winter. You can't really see any issues with the jet, but it starts surging, so I know I have to clean it. The set up on my little toro is a pain because I have to remove one of those carb mounting studs in order to be able to swing the carb so the linkage can be removed. Perhaps I just don't know "the trick" to getting the linkage off. I should have kept the old two stroke Toro sno thrower, that thing was a beast and the carb never got dirty. Gave it to my brother, much lighter and more powerful than the 4 stroke I replaced it with. Wonder who makes the engine, Toro??
You don't even have to take the carburetor off. Unscrew the bowl bolt and take it down - and then take a small screwdriver or an L screwdriver and take the jet out and the tube - clean them up - put them back in - put a rubber gasket on the the bowl and bolt it back on.
I really like those plastic carbs Briggs uses on the consumer OHV engines, I know a lot of people hate them but, since the whole fuel system is plastic except the press fit jets corrosion seems to be less of an issue, and if you do need to clean them you don't even have to take off the carb and fight the linkages, you just use a 7mm to take the two bolts off the bowl and use a flathead pry it off, then use the flathead to pop out the jet cartridge.
Correct but the jets are so small they get continually clogged if you do not keep debris from entering the fuel tank. You would be surprised how many of these at Eliminator Performance in Canada had a fine piece of dried grass stuck in the jet.
usually just removing the bowl screw and spraying up into the jet with carb. cleaner does the trick. Saves from disassembly. On some the jet is part of screw then just clean it after removal
Thumbs up! Thanks! I enjoy all of your videos while learning quite a bit. Curious, with you draining bad fuel out of so many machines, how do you dispose of it? I don't want to store it. Oil recyclers don't want it? I end up spreading a 2 or 3 ounces in a pan and let it evaporate. Takes forever!
Are these carbs different than those on a gas pressure washer? Every year like clockwork, if the washer won't start on the first couple pulls, (especially after sitting over winter), I know to clamp the gas line, pull the bottom bowl off and clean the orifice in the nut. Starts up effortlessly after doing that.
I have a Husqvarna 21" mower the model i have doesnt have a fuel filter which is strange i guess that Husqvarna wanted to cut corners nonetheless once awhile i have to tear apart the carb & open up the fine hole in the carb with a paperclip put it all back together then runs fine but first mower i owned without a fuel filter.
I always thought the fuel level in the carburetor bowl was below the gasket and the purpose of the gasket was to seal the bowl so the primer worked and air did not leak into the carburetor?
All ya need to do is go to menards buy a mtd petcock kit,,cut the fuel line and install petcock…then whenever you are not gonna use your lawn mower ,snowblower ,,motorcycle,,shut petcock off and run,engine till it dies…I’ve been doing this for 40+ years and the engines start up every time…😊😊😊
Hey Don I couldn’t help but notice you didn’t clean the pilot jet? Was there a reason for that? I find that they are always blocked. On your advice from a previous video I purchased a micro drill set and use that to clear the blockage and open the jet slightly. Cheers
..."premium" gas here (southeast Texas) still has 5% corn-liquor....I drive for miles to get corn-liquor free gas.... 60 cents a gallon more than regular, but well worth it for all my small engines... 🙂
Hi Don I noticed there is a hole above the air intake on the carb where a choke shaft would be if one was fitted, was the hole open to the air or blanked off like it should be with a primer? Thanks for the vids I learn something new with each one.
I have Yellow CC and it has that choke (hate it) but Im betting you could interchange the carburetors, they look identical, I'm betting that cab is used on many, many models.
Fog and use stabilizer tge red stuff you will never have a problem every again. My dad and I been doing it for years. All are small engines and outboards and inboard engines all ways start right up every year.
I like the flattening of the bowl seal area . Also the little metal sleeves sometimes fall out of plastic filter cover . In case your wondering where did these little bushings come from . 😂👏👍great video
Thanks for the video sir! Interesting that *this* China made mower has _studs_ vs _bolts_ securing the carburetor to the engine. *Honda* seemed to never learn this.
grouse work Donny mate and cheers from Australia 🐨🐑🦘🌴🌏 to your area in Canada 🍁 and i do believe that,s a engine that,s a clone copy of a Honda just looking at the fuel cap too but yeah it looks like a good runner to me etc.
Engine looks like the Honda engine on my mower, but this one could be an 'imitation." And I always (I mean always) drain all fuel from small engine equipment at the end of the season. I have my mower 10 years and never had this problem. After running until dry, I tip the unit over to get every last drop out, and never bother with putting in oil or trans fluid.
Carb cleaner is a very aggressive solvent. It will swell an O-ring very quickly. That is why it stretched and had to be replaced. If you don't believe me, put one in a container with carb cleaner and watch it happen.
Donyboy73:::: The Sears/ Briggs Stratton Mower we have is hard starting and it has that plastic carb..…the filter box has the primer bulb in it…..when I removed the filter box to access the carb I noticed there is no hose from the back of the primer direct to the plastic carb….just the large vent hose….I’m confused….shouldn’t there be a primer hose or is this carb not designed for one….pushing the primer bulb 3 times to push air into nothing or do they hope it enters the carb ..HELPPPPP!
Nice work man! Is that a Kohler knock off? I’m trying to adjust an automatic choke setup on a Kohler mower right now but I’m starting to wonder if the mechanism next to the muffler isn’t working properly? Do you just test those with a torch to see if they move?
First thing I do is take the carburetor bowl off because I know it probably has water in it. I ALWAYS drain out ALL the fuel on someone's non- start mower. I usually drain it in a container so I can see the huge water bubble in the container. I usually take a small video for the owner to see. After cleaning out the fuel system, they usually start right up. I then tell the owner to dispose of any and all fuel in their gas can and go buy recreational fuel. 90% of the time, they tell me they just filled the mower and or fuel can. I tell them their can is contaminated with water, unless it was bone dry, I can guarantee there was a LOT of water in that can. On an engine that surges, it's best to go through and open that main jet just a bit. I usually use the step up method to closely monitor how the next size up hole works . It may take time, but the owner will thank you.
I have a cheap Poulan mower for trimming around the trees & bushes. It always surges when it is cold, but eventually smooths out (mostly). I took the carb apart, found no dirt or corrosion, cleaned everything anyway, no change. I've been told surging indicates it is starved for fuel; I thought I might need to adjust the float up a little to let more fuel in? Or is drilling out the jet a more likely next step?
@DaddyBeanDaddyBean I would drill out the jet. Just be careful and always go just one drill bit size at a time. I have a set of micro drill bits I purchased at a hobby store. It has always worked for me. If you go to large of a drill bit, you cannot add back what you took away. ( Well you can...using fine craft wire) I generally will not do this on a customer's mower or blower unless they say it's ok and no other method to stop it works, such as replacing the carburetor.
Kinda hate how almost every small engine uses the same exact carburetor design today. I really do miss the old Briggs and Stratton carbs on the quantum engines, and those things were stupid easy to clean.
Watch Next ➡How to fix a surging lawnmower;

That's a Chinese knockoff of a Kohler engine correct
I watched that one too. Great videos and a cameo appearance from donyboy's pet chipmunk on the surging video.
Great info from start to finish! Unedited is fine, just like our real world! Keep them coming.
It's the most wonderful time of the year 😁 Nice fix on the bottom of the carb bowl. I learned something today. Thank you.
Now that is hard to believe Stella and from a young guy like Donyboy eh. LOL
@@waynestefinashen239 🤣 It's true.
Yep..Gunsmithing screwdrivers are awesome for removing jets. Hollow ground ends and they fit very well.
Good job!

It was so easy to clean the idle jet, you were right there.
Remove the bowl gasket before you spray carb cleaner. The carb cleaner cause the gasket to stretch out.
i have also heard if you boil the gasket in water it can sometimes shrink
Clear, no-nonsense instructions every time! Many thanks!

Put some Mechanic In A Bottle in the fuel tank to clean the system and use regular starting fluid the first time and let it run for 5 minutes.
Your the best Don
Excellent. Thankyou
Craftsman WS4200 Coils keep failing. Any ideas?
Que buen video Grasias por alludar
I like the flattening of the bowl seal area . Also the little metal sleeves sometimes fall out of plastic filter cover . In case your wondering where did these little bushings come from . 😂👏👍great video
Right on Bob i normally put a little SealAll glue around them on the OD so they never fall out again.
Thanks for the video sir! Interesting that *this* China made mower has _studs_ vs _bolts_ securing the carburetor to the engine. *Honda* seemed to never learn this.
Great work, Dony 👍🏼
grouse work Donny mate and cheers from Australia 🐨🐑🦘🌴🌏 to your area in Canada 🍁 and i do believe that,s a engine that,s a clone copy of a Honda just looking at the fuel cap too but yeah it looks like a good runner to me etc.
1:23 way to use old gas to clean the outside of the carb. 😊
yes lol!
Hey Dony. Thanks for the tips. As always, great video.👍👍🍁
Nice job👍
Carb spray always swells those bowl gaskets. 😣
Engine looks like the Honda engine on my mower, but this one could be an 'imitation." And I always (I mean always) drain all fuel from small engine equipment at the end of the season. I have my mower 10 years and never had this problem. After running until dry, I tip the unit over to get every last drop out, and never bother with putting in oil or trans fluid.
Great content. Thank you!
Nice. Though I’m not quite sure about messing with the jettings. I feel that you were a little too aggressive with it.
Carb cleaner is a very aggressive solvent. It will swell an O-ring very quickly. That is why it stretched and had to be replaced. If you don't believe me, put one in a container with carb cleaner and watch it happen.
I noticed a lot of smoke coming out right after starting not sure why????
Gotta have torch tip cleaners ! ☝️🤨
I Love these repairs. Run it dry and empty the bowl !!! 🙄 Ethanol ??? 🤔
What is the name of the Screwdriver ?
I think he calls it Jim.
Anything can be fixed, just comes down to , is it worth fixing?
Absolutely!
Donyboy73:::: The Sears/ Briggs Stratton Mower we have is hard starting and it has that plastic carb..…the filter box has the primer bulb in it…..when I removed the filter box to access the carb I noticed there is no hose from the back of the primer direct to the plastic carb….just the large vent hose….I’m confused….shouldn’t there be a primer hose or is this carb not designed for one….pushing the primer bulb 3 times to push air into nothing or do they hope it enters the carb ..HELPPPPP!
Nice work man! Is that a Kohler knock off? I’m trying to adjust an automatic choke setup on a Kohler mower right now but I’m starting to wonder if the mechanism next to the muffler isn’t working properly? Do you just test those with a torch to see if they move?
Check the z bend in the choke linkage. Extend or take up the slack to just close choke when cold.
Where can I buy that screwdriver set? Looking for one for my Honda snowblower. Can't seem to find it anywhere. Thanks
they are gunsmithing screwdrivers from EAGLE
Thanks for the vid
Good job donyboy73.
They must have sold alot of those mowers. I had 2 in the shop in the last weed. One for a coil and one for a recoil repair.
My girlfriend told me it’s either Donyboy 73 or me, I don’t remember my answer but I have to cook my meal since😅
oh no!
Awesome video
First thing I do is take the carburetor bowl off because I know it probably has water in it. I ALWAYS drain out ALL the fuel on someone's non- start mower. I usually drain it in a container so I can see the huge water bubble in the container. I usually take a small video for the owner to see. After cleaning out the fuel system, they usually start right up. I then tell the owner to dispose of any and all fuel in their gas can and go buy recreational fuel. 90% of the time, they tell me they just filled the mower and or fuel can. I tell them their can is contaminated with water, unless it was bone dry, I can guarantee there was a LOT of water in that can. On an engine that surges, it's best to go through and open that main jet just a bit. I usually use the step up method to closely monitor how the next size up hole works . It may take time, but the owner will thank you.
I have a cheap Poulan mower for trimming around the trees & bushes. It always surges when it is cold, but eventually smooths out (mostly). I took the carb apart, found no dirt or corrosion, cleaned everything anyway, no change. I've been told surging indicates it is starved for fuel; I thought I might need to adjust the float up a little to let more fuel in? Or is drilling out the jet a more likely next step?
@DaddyBeanDaddyBean I would drill out the jet. Just be careful and always go just one drill bit size at a time. I have a set of micro drill bits I purchased at a hobby store. It has always worked for me. If you go to large of a drill bit, you cannot add back what you took away. ( Well you can...using fine craft wire) I generally will not do this on a customer's mower or blower unless they say it's ok and no other method to stop it works, such as replacing the carburetor.
Kinda hate how almost every small engine uses the same exact carburetor design today. I really do miss the old Briggs and Stratton carbs on the quantum engines, and those things were stupid easy to clean.
im thinking the low idle was the starting problem all along
Bowl seal didn't stretch. It swelled up because of the carb cleaner spray!!!!!!!!!!
enlarging the jet hole doesn't make the engine run too rich?
no unless you over do it
Put the bowl gasket in boiling water for a little bit to shrink.
will try!
Great stuff!
Good job 😊
👍👍👍Thank you.
