I’m interested in the back wave effect.

NordriOfUthgard

Is that stream going to be available as a VOD? Would love to see this but this week is not having any remorse with me before saturday evening.

Mikkel Jørgensen

I really want to see you deep dive on the more advance types of carburettors like a CV, flat slide or round slide. I have a motorcykle with CV carbs and one with round slide, and I have found that there is a lot of information and assumptions about what different adjustments does to the mixture at different flow rates (RPM) and I really want to know what the truth is in an intuitive way. Some of the adjustments I know of is Main jet size, pilot jet size, idle air or fuel mixtures screw, needle height and float height. All if these have different effects and to get a good running engine at all loads and RPM you have to spend a lot of time messing with it.

Myron Dietz

Great video! Thank you for sharing the thrill of discovery and it was heart warming to see you and your dad interacting.

Nik Balson

You are a true inspiration, I love your curiosity and enthusiasm

Geoff Bowering

Evidence of prior Destin experiments in dad's garage? - 10:45

Jeff Myers

I hope you had Gav and Dan sign the ceiling.

Stuff Made Here

Attach the clear carburetor to the clear engine!

Ben V

Awesome!! I've always wondered!

Paul Tremblay

This tickles all the right parts of my brain. Beauty-engineering-engines-family ! Thank you again and again for what you do !

Allen Lea

I couldn't be happier with this video, Destin. I absolutely love the interaction between you and your dad. It makes me miss my dad even more, but I can see how much you cherish your relationship and these videos will be more precious to you later than you can fully realize at this point. I wish I had something like this of me and my dad. Keep up the excellent work. I hope that you and Matt discuss this interaction on NDQ. I would enjoy hearing that conversation very much.

Jonas Wahlen

Great video Destin! Thanks for sharing your curiosity! Also, gotta love your "Bama" shirt 😊

Scott Montague

Awesome video Destin! When I was 12 years-old I helped my father rebuild the carburetor for his 1966 Mustang. I had been his "tool guy" for years running back and forth from the garage to whatever project he was working on. But this project served as my own introduction to mechanics, and awakened my passion for understanding those systems as well as using my own two hands to work with them. I think that spirit of just doing, and your commitment to your family, is why I appreciate your channel so much and I hope this video in particular can inspire young minds the same way my own experiences did!

Charles Thomas

Wonderful video Destin, reminded me the first time I looked down into a Holley 4 barrel while my buddy worked the throttle. I learned more about atomization in that 10 seconds than most learn in a lifetime. Then I learned another lesson: if you look into a carb and it backfires you hit you head on the hood. Good times.

Ed Strong

Loved this one! You were close to a problem I think at about 18:00 minutes in. It looked like you were getting flames back out the intake of your carb.

Nicolas Simon

Wowww what a great video! It was so interesting to learn and came right on time as I am studying for my Pilot Licence, this way I won't struggle on the carburetor part. Thanks so much for your videos Destin, they're amazing. (Your dad indeed looks like a great teacher)

Ray Markham

I am an auto mechanic and I own my own shop. Me and my boys always enjoy your videos and I can't wait to share this one with them. I have been working on carburetors for over 25 years on cars and small equipment. This video is without a doubt my favorite as even though I can fix them I have gained a deeper understanding WOW thanks Destin keep it up. Also thank your dad for me it is men like him that took the time to teach me and I try every day to pass it on to the next generation. Thanks Again.

AlexLogical

This video is excellent!

Adrian de la Rosa

Thank you, Destin. This kind of video is the reason why I am Patreon of this channel.

Mateusz K

Awesome! I would like to see how icing conditions occurs.

MarkOH Branstetter

This video blindsided me. My dad is gone now. The interaction between you and your dad made me appreciate the time I had with him. Thank you.

Erin

Great video Destin, and one that I'm going to send to my own father. If you'd want to continue with carbs at all, I'd be very curious to see the same demonstration with an aviation-style carburetor, which regulates the fuel-air mixture differently (most commonly by directly metering the amount of fuel that can come into the jet, I think). I guess it's a minor difference though

Scroaty Ball Sac

Destin... this video is like seeing my imagination for real...thanks again... I'm stoked I'm supporting you.

Timothy Thiele

Destin, this entire video is amazing! Thanks so much for exploring what you love and letting us come along with you and your Dad. Also, can't wait to see what you do with those new found python skills :-)

VitAnyaNaked

The video is really great! I am very glad that all the videos that you make give everyone pleasure, this is the main thing!

Ed Williams

Dude!! Your dad is awesome! But you know that. Really cool video. Thanks!!

Warren DeMars

Great video!!!! I see an couple of options you can also explore, should you decide to keep going: (1) a carb is sized to the engine, e.g. it's throat size, max mixture at a specific RPM, etc.; (2) carb throats are circular, again, helps with *laminar* flow, to better atomize the fuel; and (3) carbs have various needles because you need a different amount of fuel for different engine RPM phases: idle, partial throttle, full throttle, more load, etc.

adcurtin

Destin this video was amazing! now I have all sorts of questions about fuel injection. Does that just replace the venturi with a very metered pump that can squirt that same drop right at the intake of each cylinder? I would love to see a video with a clear intake manifold showing that ;)

insideHardware

Loved seeing the Venturi effect/suction work when applied to a practical everyday application. I also loved the interaction with your father and the way you chose to document and include him. Your videos often have that "human element" that help keep them unique vs just a hands on lecture. On top of leaning the mechanical principles, high speed footage, 3D models and diagrams, you take the time to include family, friends, other youtubers, military personnel by name, scientist.... it's great! thank you. proud to be a patreon

DogBreath

Nice. On one video I recall you shared the high-speed footage. Think you could do that with this? I'd like to review and share with my mechanic friends. Do you share the full file or a movie like file? Cine or similar vs MP4.

Jim Straub

Hi Destin. I love your videos. I do have a comment about carbs. The Venturi makes the air speed up and then when it is over the high point there is a drop in pressure and that sucks the fuel from the bowl. Think of the wing of an aircraft. There is a low pressure area behind the leading edge on top of the wing providing lift. That engine can run even if the fuel is below the carburetor. The tank on my riding mower is below the seat. This makes it harder to start so many companies put a fuel pump on the engine. At least this is what a mechanic from my past 30 years ago told me. Thank you and your dad for doing things like this. You rock.

Jack Griffiths

Thank you so much for ALL the content you provide us. I can speak with 100% confidence when I say that you inspire so many prospective STEM students.

David P

Many thanks for this video. This was a brilliant project and video on so many levels. First it was great to see your Dad and your interaction, it made me reflect on how I could be a better teacher for my children. Second I understand so much more about the carburetor now. Third this was a brilliant example of engineering vs science, that something can be chaotic but still good enough to work. Fourth, how was the carburetor arrived at? - it's an atomizer but where did the ideas, precursors and understanding the need come from - I have some homework to do.

Ton Vaes

Hi Destin! This was fun. The shot shot from the inlet, showing the drop get flattened out was fantastic. The video also brings back sweet memories from my dad and his father who where enthusiastic engineers and inventors. So thank you twice! Ton.

Joshua Griffes

What a great video! I understood in theory how this worked. But seeing it in slow motion made it make so much sense. I feel like I finally have basic grasp on carburetors now!

Scott Cress

This was infinitely more entertaining and educational than I was expecting. Thank you for making this.

Tim Tobin

You can see where you get your brains from :D. This was a great video and I used it to show my son how the carburetor on his 4x4 worked. I've told him probably a dozen times how it worked, but you were able to open his eyes with AMAZING shots. Thank you so much for what you do!

Eric Westphal

I always imagined the fuel atomizing right as it left the feed into the venturi. I guess if you have a needle valve, it might vaporize it a little more? Really nice stripped down model though--simple but worked great!

Rick Corbitt

Wow, way cool. Thanks, Destin!

Steve Wells

Really interesting, I've always known what a carb does, but never understood how. Thanks! Now I just need to work out how the pilot jet & main jet interact.

Jason Allen

Hey Destin! Great video as always! This video, and especially rewatching the one on the transparent four stroke engine, got me thinking... I work in landscaping, and it's my understanding that all of our gas powered tools —like the weed wackers you featured in their own series— have two stroke engines. I now understand, thanks to you, how a four stroke engine works, but even having seen simple animations of a two stroke engine, I do not understand what's going on in the tools I use on a daily basis. Is there any chance you might continue this developing series on transparent engine components so we can see the inner workings of a two stroke engine?

Jason Sprague

Hey Destin! Wow. Watched this on a day I really needed to see such a great experience. As usual you are able to capture the beauty in the complex things we take for granted. Having rebuilt a fair number of carbs I never knew how amazing the mechanics and physics of them was until now. Thank you for the continued awesome content!

bill miller

Your dad is way cool. Just wanted to say that!
