Holy sh*t this is the best video I’ve ever seen! I feel like I learned more in this video then I did in school from preK to senior year lmao!

Man, I went to school for motorcycle/atv repair, and have worked in shops for several years, and nobody has ever explained carbs as well as you just did! All I can say is wow, and thank you.!

I've been a mechanic for 7 years, I work on old cars, chainsaws, motorbikes, and have messed up more carburettors than I'd care to admit, to get to the point I'm at now. When I did my apprenticeship the training organisation only spent a 3 hour lesson on carburettor function, and we never worked on one. This video should be standard viewing for any mechanical course. It explains everything perfectly, and I'll be sharing it with anyone who cares to listen. Well done, and thank you!

An enthusiastic young expert is always much better than a classroom teacher. That was perfect. Thank you

I've been tuning carbs for years on everything from 2 stroke to brig's to VWs to racing V8s and many multi carb set ups from street strip racing and off road rigs. You have definitely explained in 30 minutes what I spent many years early on to learn trial and error as a young man. I'm the go to guy for my buddies when it comes to tuning carbs and timing and over all engine flow from air in to the exhaust out the end of the tail pipe. From now on I'm sending the guys that come to me to your video so just maybe they can learn for themselves. Teaching guys about tuning carbs is like talking French to a Spanish taught cajon You got it covered down to plain English.

A lot of work went into this and I hope everyone learns something and appreciates the trouble this guy went through. I'm 73, been flying two cycle ultralight aircraft since 1978 (call it 44 years) & recently Paramotors. Even I learned quite a bit from this. Many thanks to Mr. Rolling Wrench!

Having been a teacher part of my life and an engine DIY-er I think this video is one of the best I have ever seen. It is extremely well planned, documented and explained part by part. Hoping you will appreciate positive comment to make it even more perfect, you could spend a bit more time on pilot jetting versus the turning of its mixture screw (with the wideband in place). As an addition you could also mention some carbs have a separate idle air-jet on the filter side of the carb. Thanks a lot for taking the time to make the video.

2 years later and this video is still saving marriages! I was so pissed off trying to get my carb tuned and the enrire time i was trying to fix my idle by screwing up everything else. Thank you so much for putting this out there!

Your gold standard video should be used to educate most video producers on how to do it right

Probably the best carb video I've seen yet. Kudos for going through tuning too! For some reason very few others do that.

This is the video on carburetors that I have always dreamt of! When you have no help or money, this video is an absolute blessing. Cheers.

Dude 2 years later and still relevant i was scared to change my carb on my 2023 ruckus due to the jetting, have a performance exhaust, air filter delete, and pressure tube and all i needed was the performance carb now im going to change it and see how it goes thank you!!!!

That was hands down the best general tuning video for smaller carbs. Very good job sir.

I ride dirt bikes with carbs. This is the best carb video I have seen on YT. Thanks for sharing Rolling Wrench

Absolutely insane how much you covered in this video. Major props to you for covering EVERYTHING in so much detail. You killed it.

I just got my first 2 stroke (banshee) and was overwhelmed by the carbs and you have simplified it tremendously. Thank you.

incredible how well this video explains carbs, never been so impressed with a youtube lesson before

I am on 2stroke carbs, but lot of info here will help me with my tuning. Thanks a TON for this!

This by far and above the best carburetor, tuning informative KZfaq video in existence. This mans knowledge & expertise makes all of these other KZfaq video’s on carbs look elementary. Great job man. Definitely earned a sub.

I've watched a lot of tutorials about tuning carb, and by far this was the best among the rest. Best explanation ever made. Now I can do a lot better in working carburetor.

Man, I just learned how the hell my carburator works, because of this AMAZING video! Really really simple and helpful. Thank you so much man

That was one very informative, easy to follow explanation of carbs! Thanks for taking the time to create such a great video, it is truly brilliant! Cheers!

Wow man that is the best tutorial and explanation I've ever seen! I knew a couple of the basics but you just brought everything to light and hit a home run! Thanks for the information.

Awesome video bro. I learned so much. Went from knowing nothing to feeling very confident in tearing into my carb. Thank you for what your doing.

I've been shade tree adjusting carbs as needed for years, sometimes great sometime horribly. That just explained everything. Best tutorial on this subject ever. Thank you very much!

Thanks for doing a masterclass in how to tune a carburetor. Extremely well done!

Great video. Watched it at breakfast, bike carb out, cleaned, jetted and running better than ever by lunch. First carb service ever. Thank you. So happy.👍👍

I saved my life with these carburators men!!!! thank u for this video s2, hello of Brazil!!

Well prepared, I've been trying to teach my son about how carbs work. You just saved me hours! This explains it better than I can. Also, I always thought back firing on decel was rich but logically, it's when enough fuel gathers to pop. Makes sense. Really appreciate your effort.

I found this really informative and as a keen motorcycle enthusiast with hardly any knowledge on how to maintain bikes I firmly believe that I could do what your video shows. I may need to watch it a couple of times more but I definitely will be having a go. Thanks for the lesson.

There are teachers, and then there are people like you. Wonderful stuff my man, you make it very easy to learn! 🙌🏼

I stumbled onto your video, almost gave up on looking further just before I did. What amazes me is after watching your video twice, I have no questions and im not pulling my hair out. Some people like to hear themselves talk and provide little to nothing important, they should watch, listen and learn from you..i know i did. Thank you for taking the time on making your very informative, quality video. I am now a loyal subscriber. Gotta love it!

Well done in order and layout, this is a process that needs attention to details, and you have identified every component to follow and understand functionality my 10 year old can tune a carb thanks to your demo . .

Very informative and educational! I had a basic understanding, but you took it to the next level! Thanks, Don

This is hands down the best carb tuning video I have ever watched. So much information presented in a way that is extremely easy to understand for anybody at any skill level. I’ve been working on small engines (ATVs, snowmobiles, dirt bikes, etc.) for the better part of 9 years and learned a lot of what I know through trial and error. Never have I ever seen somebody explain carb tuning so well and make it as simple as you have. Amazing video! I learned a couple things I wish had learned when I first started.

Fantastic job explaining this whole process. Extremely thorough while being easy to understand !

I can just tell by the length of the video and your intro that it's worth watching. I've messed with carbs on 2 strokes mostly and even have my banshee with 2 synced carbs working perfectly but really appreciate these videos. It's free continued education

Excellent video...My 2 stroke dirt bike was bogging down off the starting line, now I know why. Thanks to this video I now know what the problem is and how to fix it. Thank you !!!

I would like to thank you for taking the time in the making of this video. I searched multiple videos on carburetor and this is one of the best I have seen. I have forwarded your video to all my friends that have ATVs/ Dirt bikes. Continue your hard work.

by far the best explanation on how carbs work and how you tune them all in one video you did a fantastic job at explaining how and why a specific change effects the rpm and mixture

That was probably of the most straight forward carb video ive seen. Keep up the great informational content!!

This is an excellent video. Months ago, I wrote of sharing value of your experience--instead of making info-tainment, this is the kind of thing I meant. I've worked on all kinds of mechanical contrivances, but back when I had my old motorcycles, they didn't have a power jet, so I learned something too. Thank you.

Just wanted to drop you a line and let you know how much this video has changed my thinking. I have NEVER tuned a carb before… not even a clue of where to begin. I watched this video 4 or 5 times, and tore my brand new NAVI apart yesterday. I live in Denver, and feel like it was not tuned well from the dealer. I also put a intake and filter on it to remove the massive air box. I am feeling more confident and informed. I bought a “jet kit” for the intake and decided to “figure it out myself.” I feel like it is getting better, and with a little more trial and error, I will get it. I don’t think I would have even attempted without this video. Thanks for putting together such a great resource for the community. I hope to make it by your shop soon. Thanks again!!!

Subbed!!! I'm a Motorcycle instructor in Ohio and our carbed bikes are Teedubs, a ton of old Rebels, and a few Suzuki GZ's. My personal bikes have been carbed and I'm definitely no expert, but I have limped my way through adjusting them so they run. Your video clarified and integrated lots of the information I had cobbled together in my head. Excellent!

The absolute best lesson I have ever witnessed on the topic of carburetors! Introducing all the "players" at the beginning so as to establish a vocabulary was a classic instructional technique. Taking the time to explain not only the purpose of each part but how their functions were related was superb! The cause and effect scenarios for rich and lean and how to remedy the situation for a near perfect stoichiometric ratio were exemplary! You have a gift for taking what can be a very complex topic and making it easy to understand so that others can put the information to use with successful results!!!

This is excellent! Thank you taking the time to explain this so thoroughly.

50 years riding and wrenching and I now understand what I do wrong - thank you! An excellent tutorial!

The best video I've seen on carb tuning, the wideband demonstration was the cherry on top.

Duuuude! You showed up exactly when I needed you. Have a PWK that I'm working on and couldn't find a decent video for that type of carb. Thank you!!! 👍

Very informative. I felt like I just took a degree course in carburetors. Great job.

You cleared up the lean/rich diagnostic question that I've been listening to people bungle for 5 years,..in just 5 seconds,...thank you !!!

Always straight to the point not a lot of BS just talks about the topic. Thank you for your videos.

This video was a life saver getting my dual carbs setup. Thanks for such an informative video!

This video made me realize that the float has a needle, when I took it apart it bounced under the tire of the mower and I had no idea to look for it until watching this. Now it's running again and I can feel like a proper home owner lol

Can’t thank you enough for the most informative carburetor tuning video

I learned a lot from this video! Every minute was worth it.

This video helped me understand so much more about carbs that I hit the Like button 3 times!

Mate I've been working on cars and bikes my whole life and have a lot of experience with carbies and I have to say your video is one of the most informative and very well thought out/planned videos on carbs I've ever seen! Good on ya! Cheers from down under! 🇦🇺

STILL the BEST video on KZfaq... Thanks soo much for making this. i just did a zs190 swap on my Grom and your videos ALWAYS help

Learned way more than I thought I would especially how that dude looked at the beginning 🤣.

The best carb tuning video I've ever seen!! been sharing the f out of it in all my pitbike groups great work

Excellent tutorial, thanks for the work you put in to this. I rode modern sport bikes up until a few years ago, all with EFI, but recently got back in to riding with a single cylinder carbureted dual-sport. This will help me tune the carb and get the best performance possible out of this little thumper.

Brilliant vid. Simplified enough for me to be confident in stripping and rebuilding a carb of my own! Great work. Thanks

Best carb video on the internet.. hats off my man!

Most helpful video I’ve ever watched can’t thank u enough

Thank you for all the time amd effort you put in to make this video. I thought I already knew how carbs worked and how to set them up and tune them. This video let me understand how my turning of screws actually altered how the carb functioned. I came across this video as the top You Tube recommendation after watching a video by Dustin of the "Smarter Every Day" channel. He had built a working see through Carburettor and uses a high speed camera To show how the carb uses the venturi principle to mix the fuel and air for to the engine to use. All though he had the choke and throttle on his see through Carburettor his video only showed the principles and not a real life carb. But by watching his video and then yours it gives a perfect understanding of the carbs working principles and then yours shows how those principles translate onto a proper engines Carburettor, what all the screws control and how to use them to tune the carb to its full potential. Both videos I think were brilliantly made, easy to watch, well thought out and turned a fiddly job into something much easier to do. Thank you for all the time and thought you put into creating a perfect mix of a good quality video and great subject and educational content. Keep up the amazing work, you just got a like, subscription and a notification bell ring. I'm now going to look at the videos you have made previously and probably binge out on them for a good while. Thanks again.

I loved this video!!! It makes it so easy to understand and when you have that one customer that has got it all backwards ,this video can stop all the what if questions before they get started... Point Blank Period!!

By far the best explanation of a carburetor and turning I’m glad this video exists!! ❤❤❤

muito bom meu amigo, meus parabéns pela aula e obrigado por compartilhar o seu conhecimento!

nice humor @ end. thumbs up.. not twice for that would remove my like.. lol

OMFG, just what the Dr needed. A tutorial on Carb setup. Thank You, Thank You, Thank You.

One of - if not - the best vid i've seen on the subject. Very clear. Thank You!

Thanks very much for such a professional presentation. I've never touched a carb until a few days ago when I started on the set on my 9 previous owner Kawasaki ZXR, none of the jets are as per the manual, and it's got an after market pipe. I'm going back to factory settings to start with so we'll see what happens when its back together or sure. Cheers again, Gaz

I don’t even own a ruckus but this seemed liked really useful info.

Excellent video, man...I learned more about carburetion in the 35 minutes of this video than I had in the previous 48 years of my life...well done

I want to thank you for time and knowledge. This is one of the best videos I have ever seen.

Thank you!!! I think now I can tune the carbs on a tank!😆

thanks for the video i thought the whole carb worked together when running also how would you do this on motorcycles with 2+ cylinders

Awesome video man! Perfect for anyone experienced to learn something but slow and detailed enough for my 10 year old to follow along!

This THE BEST video on tuning a carb, hands down. Bought my wide band tuner from RW, very much worth the money! Saved me hours or trial & error.

Dude, I think I just got my masters on carbs.

I learned…..about a semester of community college mechanics

Your brother are amazing. Thank you. I don't have it fixed yet but I'm going to thanks to your video. Fifty-three-year-old pipe welder definitely mechanically inclined but never fooled around with carburetors. Just bought a 2002 Kawasaki zx7r. Great bike but has carburetor problems thanks to you I feel better and I'm working on it.💖💖💖💖

This video can turn a newbie into pro (with some hands-on experience) The best carb guide video ever

By far the best clip on carburetors. Thank you.

you deserve appreciation 👍 i have watched tons of videos on carburettor adjustments, but none of them explained the things that you did, specially O2 sensor thing 👏👏

Good work! Thanks for teaching thousands of people on a subject that can be confusing easily

Been having issues getting my kids bike dialed in this video just broke it down and got me what I needed! Appreciate you brother!

I have never seen a better video on anything in my life ! Great job. I'm definitely saving this for later...

Mannnn this is the best video on carb tuning I've ever seen and believe me I've seen a lot

Thank you so much for making this video. A lot of work went into the production of this video in order to teach us.

You nailed it, all in one technical explanation as connected to the actual site condition. Double Thumb's Up. This guy , he knows what he is talking about with solid output and really skilled unlike others that are pretenders .

Thank you for putting this all into layman's terms! I get it, I understand what your saying,I'm definitely learning. You my good sir are an excellent teacher. Thank you again 😊

Was having trouble jetting my bike. Got it sorted because of your excellent video. Thank you for what you do.

For dummies like me out of all the YT videos I’ve seen on how to tune a carb your explanation was the MOST thorough and understandable! I have a 2 stroke Daelim Cordi and just slapped on a power jet carb to see how it works. I had problems with what jets to use but after watching your video it runs like a champ 54mph I almost gave up on this carb but thanks to you I didn’t waste my money. Thank you very much keep up the good work 👍👍

That is probably the best video on the web. Thanks. Well Done, Great Job

hands down the most informative carb video i've seen. Thanks

Thank you so much, got a old 2003 Yamaha ttr90 that sat for 10 years in a garage, got a new carb and kept rev bombing as soon as I started it, thanks to you it runs beautifully

I'm working on my wpb and just cleaned the carb. You've earned a sub just for effort labeling the parts alone. Half way through the vid, very happy 👍

you are the first person I subscribed to after watching just one video even though I am currently working on a different type to carburetor but this video was dope. rock on .
