HOW TO TUNE A CARB / CARBURETOR (step by step guided)

If you are looking "how to tune a carburetor" or "How to re jet a carburetor" I have got you covered. I will show you step by step how to rejet, tune and even clean your carb. I will also show you what each carburetor component does. This will include the carburetor jets, pilot and main, float adjustment and air/fuel screw adjustments along with the carburetor jet needle clip settings. By the end of this video you will learn how to tune your carburetor, clean your carburetor, and even know what each tiny component does. You will have a good understanding of how high altitude and performance exhaust and filters change the air fuel mixture in your carb. please comment what you have learned if any so I can have some feedback on what my next YouTube video can be about.

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.

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

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.

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

[JeremyFromScience]

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.

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!

[OzzieBloke]

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'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.

[spieftech]

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

[AKAOmnivore]

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!

[danielsale]

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.

[frankmatthews]

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!!!

[David-kfpt]

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

[VoxJ]

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

[calvintaziar]

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.

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!!!
