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 KZbin video can be about.

Great video! At a point where I love working on everything myself , and this helped me so much about tuning a carburetor. So anytime you need to adjust pilot or main, you put different size jet in entirely? Needle jet you can adjust w the different rings on needle....

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!

[@RollingWrench]

Sheeesh! Thank you so much for the kind words 🙏🏻💯. I appreciate the support

[@jyellowhammer]

Agreed!

[@user-fy6gm5zf7o]

I am a snowmobile/ATV/PWC mechanic of many years. This video was exceptionally well done. Something to add.. You start with the pilot circuit because that jet is there from beginning to end. It continues to spray along with the other circuits. You need to get that one right first. He does exactly that, I am just pointing out why. Excellent video, well done sir!!

[@craigzody963]

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.

[@punchmonkey4350]

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!

I like how you put marriages in there because it most definitely makes for an angry husband when he can't figure out how to adjust his damn carburetor! Haha! That was me a few days ago, now it's time to put this video to the test and adjust that carb!

[@stiefbeen22]

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.

Your tip saying to make sure the "throttle cable has some slack and free play" saved me because my throttle cable was too tight and pilot jet was too small. Thanks for sharing your knowledge and keep up the good work!

[@frankmatthews3755]

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!!!

[@mickcaulton001]

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.

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!!!
