A small engine repair wouldn't be complete without a dog jumping through the hole of a tire on a lawnmower you just fixed. NICE!

If you're a doofus like myself, it's good to take pictures with your phone of the carb when you're taking it apart so you know where everything goes when it comes to linkages and springs.

The carb clean and detailed explanation of how it functions was top notch and the pet tricks at the end was icing on the cake.

I’m sure a lot of your viewers will learn something from this video. Thanks!

Got to love fairly easy fixes. I know most people are intimidated but you did a great job explaining it

I absolutely had to give a like to this... Not only was the information and breakdown great, but to finish it up with his pup was awesome... Keep it up buddy

Iv watched a lot of small engine Carby videos but this one has given me the best understanding of how it works and how fix it . You articulate this stuff very well! Thanks

This is the best explanation of how small carbs work and why they don't work that I have seen!

Great video! I jumped thinking the dog was going to get his paws under the deck when you started it!

I just did this for the first time. I thought it was just old but I did this and so far no more surge. I was going to scrap the lawnmower thinking it couldn't be fixed. Thanks for posting this.

I watch a lot of the diy tricks or tips videos to fixing things. I always want to add to my everyday self sufficient knowledge. And im normally disappointed at the how to videos that are just common sense or someone who has no idea what they're talking about. Bullshitting through a useless video to try to get some attention. You are the one person that I watch who has legitimate info worth watching. Even if it's something I already know you often explain the process to where I learn a little more into why that way works. And you have torn into these things and figured them out yourself. Your not just regurgitating something you saw another you tuber do or read from a forum. I don't write fan mail comments ever. But you approach things the way I try to. Which is if someone made this I should be able to figure it out. The person who made it wasnt a magician. I'm smart enough to follow simple steps backwards And im just stupid enough to try something new see if it works. Sometimes things turn out better. And sometimes I make things infinitely worse. My backyards full of buried abortions from stupid ideas. But I also have a bunch of stuff I've modified in some way and are vast improvements from what they were. anyway thank you for covering stuff i want to know that nobody else seems to be doing. and please keep doing everything exactly the way you have been because it's much more beneficial then having something explained by a self professed expert more concerned with appearing smart then engaging others to use their problem solving skills and figure stuff out. Or possibly just break things a little less until they work.

Finally a proper explanation of the idle surging on the GCV engine. Thank you! This has been driving me nuts for the past year.

Thank you for making this video. You explain everything so well. Took the mystery of how the carburetor works right away for me.

Classic restricted carburetor idle circuit 🙂 Great tips!

When I clean a carburetor, I spray, poke and blow out all the holes, everything. Have a very high success rate as a result. If you are not mechanically inclined, don't kid yourself or waste your time, take it to a shop. Most customers change the spark plug and give up.

Thanks for the detailed explanation of how the idle circuit works, and why the engine surges when the idle circuit is blocked. As you said, it's easy to fix if you understand how it works. Also, thanks for making this video. It helped.

Thank you for taking your time to teach us knuckleheads something useful. You saved me from buying a new lawnmower. I didn't have a piece of grass in my carb, but it was really gummy.

Perfectly explained. Thank you. My generator only runs while fully choked. I’m going to try this

This is a great breakdown of 90% the problems I see in the shop now a days ! Great job!

Best video on cleaning a honda carburetor I’ve ever seen. Thank you. This is the exact model I have. You are the best!

Spray some gumout in the carb and some into the gas tank if you don’t know how to take a carb apart. You might have to work the throttle by hand if to rev it up if it starts to stall when you spray it. Use short bursts.

Had a craftsman lawn mower with that same engine. Three years and it started surging. I took it apart and clean the carb out thoroughly. Work for a while but later that year started acting up again. I took it to Honda and let them clean the carb. They soaked it got it back later that day worked good but a few Weeks later started acting up again. Took it back and they soaked it overnight. Worked good for a while and then started surging again. I got some seafoam, the fuel tank was almost empty so I put a good shot in there. Pulled it out of the shed, kick some snow to the side and let it run for 10 minutes. Pushed it back in the shed and said " pos if you do this next spring you're gone". Used it for 11 years after that with no problems ever again. Sold it a few years ago running in mint shape cuz I bought a Makita battery operated lawn mower. Gas is crap these days! Don't dis' seafoam! 🤣🤣🤣 But good video!

Great job I'm sure you saved so many headaches for hundreds of people. I just had my mower have a issue with surging and it was the float valve hole had junk in it.

im a visual learner, and it really sux yt wasnt around yrs ago to watch the smart ones like you show us, you know how many small engine items to vw related engines i have dumped do to lack of knowledge i kick my self in the ass all the time lol, thanks Moe for all your shaed knowledge and expertise

Great video! I just revived my 12-year old Honda walk-behind by following your instructions. It was surging and would only start with a spray of starting fluid. I had replaced some gaskets and sprayed the carburetor before, but it didn't help.Your video gave me the confidence to try again. About the hardest part was figuring out which way to put back the plastic intake port that goes between the carb body and the engine intake. I also did a valve lash (both settings were off by about two one-thousandths of an inch.) After all was done, the engine started on second pull. Then it restarted many times after shutting down. I can't thank you enough.

Yeah , thank you ! On my way outside to take care of the surging lawn mower clear & to the point Thanks again 😀

Just FYI, when cleaning carburetors that were all gummed up with old gas residues, I found that 91% rubbing alcohol (isopropyl alcohol) worked better than anything else. Give it a try sometime.

I have found lots of mowers blowers power washers etc and I don't know how to fix them because of the carburator so I pick them up and sell them for a small fee but now thanks to these tutorial I will fix them and make more money thank you for the information 👍

Glad you made this video. I know you've made many carb cleaning videos in the past; I've referenced them many times. This newly refined video was needed.

Great video. A good concluding statement would mention the fact that almost nothing could be added to the gas tank to get rid of grass clogging the idle jet. You have to take the carb apart!

Great video. Thanks for taking the time to break that down for us!

Great advice and how-to Moe, thank you! Ginger proves every time that her breed is one of the smartest in the world! She's an awesome best friend to have! I look forward to seeing her in your videos. Thank you for taking the time to add her into your videos!

Very timely video with Spring in full swing!

I have 4 generators and 2 gas-powered lawnmowers and weed whackers that I'll be needing to do this to. Thanks again for the awesome tips!

My snowthrower was surging this past winter. I used SeaFoam and it really did work. It stopped surging relatively quickly. I tried it out because I didn't feel like taking the carb off my snowthrower in the dead of winter, lol. I will be taking the carb off in in off season to clean it out though.

Nicely done. I fixed my carb by just poking around in all the holes and jets and squirting carb cleaner everywhere. This explains the chaos 👍

I, regularly, start my 15 year old Honda lawn mower every 2-3 months during the winter and NEVER have problems! Don't invite trouble... run your mower once or twice in winter. After enough water makes it through the carb, LOTS of problems!!! Start the mower once or twice during winter... it'll be ready to go in spring! Let it run for only a moment or so!

I feel like I finally understand carburetors now from a practical point of view. Thanks, have a beer 🍻

That was a great demo for cleaning a carb. Some simple things an amateur, like myself, require a pic or notes. Such as which way did the float go or how to stop gas coming out the disconnected rubber tube

GREAT video. All the others cover the pilot jet only. My mower still surged after cleaning the pilot jet. Your video provided the answer. It was the main jet that was clogged. She’s running smooth again. THANK YOU!!!

Thanks for the inspiration! Not sure why I waited until 3am to start on my Honda's carb but it runs great now at 5am😀. I used some copper wire from some lamp cord. Most of my time was spent trying to find my carb cleaner that I had set aside for this job a couple of weeks ago🙄duh

Thorough explanation. Great video. Thank you for your content .

Many thanks for your great explanation of how this carburettor works. The absolute clincher for me was the fact that you referred to the Emulsion tube correctly- I’ve seen other people’s carb repair videos but they didn’t seem even to know what it is.

Very well explained and easy to understand. Cheers mate, Stuart 🇦🇺

Great teacher, and his tire jumping sidekick completes the lessons.

THIS IS THE BEST VIDEO ON UNDERSTANDING HOW A CARB WORKS AND HOW TO CLEAN . GREAT JOB EXPLANING EVERYTHING . THANK YOU .

I've cleaned a lot of carbs and you did a fine job, however, it was the word "Quickly" that enticed me to watch you do it thoroughly.

I love your way of explanation, so simple and easy to understand. The dog is amazing as well 🥰

Best quick explanation of how a carb works. Lawnmower carbs have been a big pain in my ass. I caretake on a farm and I am constantly working on small engines. You just got me a future big "pay raise". 😆😁

Mine was surging, took apart and cleaned the carb twice, no fix. After watching this video I realize that I missed cleaning the internal intake tubes that allow idle. Going back tonight and doing it! Thank you!

Thank you for this video post. He did an excellent job explaining everything. I am definitely saving this one. Be blessed my friend. John.

Great explanation of all parts inside. I've had a riding mower sitting for years with bad gas. This will help tremendously. Thanks!

Your videos are GREAT!!! I’ll try this one tomorrow and the freezer fix a week from now👍👍

Thank you this is the best break down and cleaning with explanation I have seen

best video about carbs on KZfaq, thanks again!

Good explanation of how it works and how to clean it, I guess a lot of people too scared to take it apart incase they can't put it back together. They could video it for themselves and play it back if they can't remember how it came apart. You've trained Ginger well

All you have to do is hold the governor open while you spray carb cleaner into the open carburetor, it will want to shut off but don't let it, work that governor. And it'll run like new. I've been in the small engine repair business for a few decades.

I had this surging problem and I am mechanically illiterate and your video made it super simple for me to clean my carburetor. Thank you for explaining everything so well!

Have a JD riding mower that started surging at idle. I ran heavy concentrations of GUMOUT Carb and Fuel System Cleaner in the fuel for a full season. By next season, the surging had stopped.

Very insightful bro. You are a great youtuber!!

Good video and advice as always. You and that dog do a good job

You answered a question I've always wondered about what or whether products actually un-gum carbs. On my own stuff, I've always disassembled and used gasoline or kerosene depending on what I was cleaning. When I worked in a shop, we used a chemical bath which worked well. Always felt that OTC stuff is a waste of time (and money), and glad to have it verified.

Thank you for explaining why the problem existed, and why you did your actions to solve and fix it. Super helpful!

Same thing happens with water in fuel. I just changed my fuel and problem resolved. Try that first. If problem persist then this vid is spot on for you.

So glad I watched right till the end, so I could see your dog jumping. He really loves you!!

Don't know why I watched this. But anyway. Really well made video that's straight to the point and indeed shows pretty much everything needed. Ultrasonic cleaner is quite good in some cases. Though one definitely needs to clean "manually" carbs before from all the shiit that's usually here and there. Mainly for jets and emulsion tube really small holes that should be cleaned fairly gently. Though jet cleaning needles are always the option.

Not only was that educational and really well explained and demonstrated, but OH MY GOD YOUR DOG 🐶 😍

I have worked on many small engine carburetors in my days. Your video is very good. Although you need to have much closer camera angles. I know what you were talking about. But the layperson would find it difficult to know what you are talking about, But I must say this was an excellent video.

You explained that very well. See you on the next one.

Thank you for the detail step-by-step in this video.. I was able to get my mower to run again with simple cleaning of the carburetor .

Why are you hating on my boy seafoam? The thing does wonders for every engine I run it through. The engine always feels much more responsive and powerful after I use it on a vehicle that has never had it done before.

This is by far the best video and most informative video I have seen for a small engine and carburetor. Great video thank you for this information!

My neighbor used to be a house painter so he went through all the neighborhoods in our area many times. When he need a mower, he would almost always find one sitting on the curb somewhere. We would spend less than 5 bucks replacing the needle valve and seat, clean the carb and they would run for years.

DANG This is why I SUBSCRIBE and LIKE you. First time I’ve heard from ANYONE about acetone. But it make perfect sense Keep it up I know you will

Great video. That's exactly what my lawnmower is doing right now

Finally someone is getting it. I have had so many costumers argue with me on this. When you are done with the machine for the year. Run the fuel tank completely dry. Then put some Aspen fuel in, not a lot. Start the engine for a minute or so then set it off the side till next year. Aspen fuel is good in the fuel tank for 3 years and good in the bottle unopened for 5 years. Aspen fuel also burns cleaner then any other fuel.

best explanation ever on how a carb work on small enines thank you

All good ! 👍 Not everyone has an air compressor , but if you do , after spraying and clearing all the passages, followup up with higher pressure air . About 60-90 psi is all you need .

very good explanation of how a carburetor idle system works. have a carburetor volvo boat which surges. I will rebuild the carburetor again.

LOL I have always just sprayed the carb cleaner through all the holes after disassembling the whole thing and it has always worked. It is so nice to comprehend what I was doing!

My brother's 2 stroke Lawn Boy use to hunt, I went through the carburetor a couple of times, no luck. The governor was the kind that blew air on a vane attached to the carburetor, I finally took some solder and added weight to the vane, problem solved. Ginger never fails to put a smile on my face, she sure is a sweetheart.

Great tip on the knife scratching the "hole" and the scratch won't wash off with cleaner. Thanks..

Excellent tutorial, thanks for posting it up!

Great well explained video and I also love your interaction with your dog. Excellent

Genius... that you sir for a very well presented topic.

This is excellent advice! 👍 I switched to alcohol-free gasoline in all my small engines. It completely eliminated all fuel related problems. There's no need to add fuel stabilizer because it has a very long storage life. It costs more but in my opinion the price is worth the lack of problems. We live in a rural area so almost every gas station has one pump that sells "real gas".

15:47 Thanks again. I hated those diaphragm carbs. Not too difficult but not as quick as the Honda and the Techumse Walbro . Always remove that carb. Really a time saver.

Great explanation of the air circuit! Thanks very much!

I used to clean carbs like this my whole life until recently when on a whim I dumped a entire carb in my sonic cleaner for a few minutes. That is how I do it now as I have had 100% success be it 1 day old or rusting in a field since the 80s. No jet hunting or passage testing just open it up and dump it in rubber and all.

I agree with the carb cleaner but the cough cough snake oil mixed in a little 1 gallon pony tank really gets my 40HP 2 stroke outboard running smoothly after sitting 2 years.

Wish I knew this a long time ago. My fuel injected motorcycle surges when I shift at high rpm. I added a little additive and it helped. I might consider acetone. Thanks.

Excellent explanation, thank you. At last I understand how a small carb works and the best way to clean it. Back to the shed to put it into prctice. Thanks!

great video, will be cleaning the same carb for the same reasons this morning, thank u

I am wondering about the effect of acetone on the plastic components especially the head of the needle valve. Will it no deform those?

Very well explained video thank you sir for taking the time, now what camera you using?

Very helpful, nice explanations here. Thanks for sharing

Good job, appreciate the detailed explanation.

I have a Troybilt Lawn Mower with that same engine on it. Someone gave it to me like 11 years ago. Im still using it.

Just want to say thank you. This helped and got me going again and it works great

I couldn't fix a hunting problem on a scythe and got a new carb from Ebay. I thought that the original carb had maybe worn with an air leak because of the large amount of rocking action vibration coming from the cutter blades. I reckon now the old carb just needs some carb cleaner to clear out the idle passage way and I might have a working spare. Much thanks for the video.
