CV Carburetor components, function animation

[@matthewcronin4245]

Helped me solve my idle problem on my ATV. Been stumped forever. SEEING WHAT SHOULD BE HAPPENING helped my understand what was NOT HAPPENING. The second the choke was closed the ATV would "sneeze" and stall. I cleaned the idle circuit and nothing changed. I started by opening the pilot air screw in quarter turn increments until I was a additional 1.25 turns out from the starting point of 2. This is the first time it has idled right since I bought it used a few years back. Big thanks...seeing the concept of operations helped me understand what I was seeing and hearing and zero in on the cause. YOU THE MAN!

[@jefffrayer8238]

What a perfect animation of how that carb works. Slowing playback to .5 makes it much easier to understand. Now I know why my Honda Recon needs the choke pulled 3/4 out to run great for years. Adjust pilot mixture screw or pilot circuit is partially plugged. Great job, Thanks so much, Subscribed.

Hello, I have this kind of Mikuni on my '91 dr250. I've been having a hard time tuning it. I have a steady idle and with a light flick of the throttle it seems to react well. When I give throttle above 3000 it goes up quickly above and then stays at 4000 for 15-30 seconds. When accelerating I don't get much power at wide open.

[@kielgalo4119]

is the adjustment screw for air or fuel?

[@inkydoug]

You made completely clear how a CV carburetor works with this excellent animation. Thank you.

[@89StarquestTSi]

I've always been able to picture it in my head but this is by far one of the best animations I've ever seen. This is why shimming the main jet seat can increase/richen up afrs in the rpms sooner

[@tahmeedaziz6840]

I've watched more than 100 videos about the working of carburettor.. but this video explained everything without even a single word. now I've understood the working of carburettor and I'll adjust my bike s air screw for best mileage.

[@PirakasK]

Great... This is the best animation in KZbin to explain the carburater working. Thankyou ..

[@agat611]

Απ όλα τα βίντεο για τη λειτουργία των καρμπυρατέρ που έχω δει -και είναι πολλά - το βίντεο σου εξηγεί με τρόπο εξαιρετικό το κάθε τι. Προσωπικά με μόρφωσες περαν κάθε αμφιβολίας κι ερωτηματικού. Είσαι καθηγητής! Μπράβο για τον κόπο και τον χρόνο που αφιέρωσες για να κάνεις εύκολη τη ζωή πολλών ημιμαθών στο χώρο.. Ευχαριστώ πολύ!

[@Fjord_Driver]

When I worked at a bike shop one summer, the mechanics would hook up IV bottles of gas to the carbs. Some bikes had 1, 2, or 4 carbs. They would point the exhaust out the door, and rev the holy beans out of them while doing all the carb adjustments to get the idle, off idle, deceleration, full throttle settings all working in harmony. Your ears play as much of a role as the screwdriver during adjustments. Earplugs a good idea.

[@zulmuhamad2299]

Animation with actual engine sound makes it easier to understand. Thank you for the knowledge shared.

[@ericcournoyer1595]

The power of the internet. Thanks for putting in the work and sharing.

[@yawningdogge]

You cannot imagine how helpful this was.

[@rubenevora5650]

No comments.. Perfect.... Thank you. Best explanation ever...

[@H0peAnL0ve]

the animation and the audio were done so well, thank you

[@slawomirb1984]

Simplest explanation ever. Good that you put sound in, it helps a lot.

[@scottcates]

This video is excellent. I've rebuilt about 100 CV carbs.

[@kendtchileninjah5905]

This is literally class worthy..I like how you did this..if I was a professor you’d have an A+ lol

Now i see why this has so many views. It's brilliantly explained!

[@edgrigsby8610]

Finally....an explanation of how these carburators work. Thank you! Now I can properly diagnosis my quads' issue.

[@grreeknick]

That was amazing! Well done. I am often-times floored by the creativity and enterprise of some of you KZbin posters!

[@dantinaglia2297]

Awesome simply awesome explanation. Cleared up the fog in my head as to how this type Of carb works and the sequence with which components work together. Thank-you

[@chrisbilling]

Great video. Idk why but the engine starting sound scared me 😂😂

[@NZHorizones]

Nice video, makes things allot easier to understand when cleaning tuning and understanding this carb!

[@Pyro17059]

This is for sure a pretty cool little video on how a carb works! Good job!

[@antoniogonzales9065]

THANK YOU VERY MUCH FOR THIS. TRULY A INCREDIBLE AMOUNT OF HELP.

[@sleightofhand4611]

The best explanation of how a carburetor works

[@JasonWW2000]

Hi, I just wanted to point out that not all CV carbs have this same throttle vacuum passage that routes through the top cap. If you don't have that extra air tube running thru the top cap (not decelleration enrichment circuit), then you probably have a cylinder shaped slide with a hole in the bottom. High velocity air past that hole causes a vacuum to form above the diamphram and when it builds up it will overpower the spring and the slide will lift up. When you close the throttle the air velocity under the slide slows down, the vacuum above the diaphram reduces and the spring lowers the slide back down.

[@samanpriyantha1763]

One of the best video in KZbin regarding Carburator.Excellent video.Please upload cooling system with thermostat in a Vehicle and more and more..Thanks.

[@travishanson166]

It finally clicked. The butterfly valve works like an air plane wing. The carb then needs non turbulent air flow in order to not run like shit in a slight breeze. Thank you for the animation.

[@hemi455]

Superb job. It should also show the filters that let air in/out of the carb chamber above the fuel and under the rubber diaphragm. If the foam in these filters deteriorates to particles, then the particles ca get into the carb chamber and cause all kinds of trouble.

[@skywaterdragon6199]

!!!THANK YOU SO MUCH!!! I'm in school and I could understand no mater how many pictures I saw this helped me out a lot

Mate, this is a really good vid. So glad that dudes like you take the time to post this sort of stuff.

[@adamjohn527]

Thnx to you. Many people though that, when the slide valve opening, the pilot jet and main jet will supply gas together. This is wrong because I have also study with the video from suzuki it self. Thnx to you bro. Kepit up

[@unsaltedlife5998]

To see the systems of the carburetor work in animation was awesome, do it again with something else please

[@wrdturkey]

Very good. Thank you. I now understand.

[@ronandowling5560]

a friend of mine has a scooter lml 150. It's running pretty rough. The other day the exhaust went pop and it cut out while riding in second gear when the choke was pushed in (not sure if you should push the choke in mid scoot, i tend to wait for the lights). She started again and although warmed up would only run without the choke pulled out.. She's also slow to react to the throttle. We were thinking dirty fuel, but looking at this i think it could be blocked pipe in the carb. Sorry i know nothing about engines, but i'm interested to figure this one out. I've got the LML 125 and she's running sweet. great diagram, i've replayed it about 10 times and i'm just getting my head around it. You have to watch one piece at a time.. Super informative! well done Athanasio. thanks..

[@ronandowling5560]

+Ronan Dowling *** sorry went pop and cut out 'as' the choke was pushed in.

Finally I am starting to understand.

[@aviinc6476]

I just saw this now, let me say thank you very nice explanation. Im doing some carburetor work for the first time, the one thing that took some time to understand is when the throttle is open there is no linkage to the slide its just vacuum that pulls it open?

[@viktorbpunkt1119]

Was hast du dir für eine Arbeit gemacht?! Wahnsinn 👍🏼👍🏼👍🏼

Very nice explanation!

[@GoPheonix2]

Well done, simple to understand video.

[@simonManleeeee]

Thats really helpful, thanks for sharing

[@pcofranc]

Awesome demo. Only thing it misses is the four tiny holes at the base of the butterfly throttle valve. Can you add that? Also, the air exchange passage for the diaphragm is missing and the choke / enricher passage is a little different on most carbs. Stil, an awesome effort! This fine points show how complex the carb is.

[@Slazlo-Brovnik]

Very informative and helpful, thanks.

just suggestion..make video focus to ratio oil and air..how to set main jet and pilot jet,.thats too many questions actually in my head but i cant explain to you bcoz i dont know much english.. sorry about my english..thanks and you're very kind.;D

[@alexdefelice2448]

Great visual reference, thanks for sharing

[@brentneves3602]

Great explanation, however the diagram never showed the 2-3 additional transition jet holes situated behind the throttle butterfly(idle position) that flows from the pilot circuit, to supply the engine with extra fuel before the mainjet kicks in, also this particular carberator style, does not cover an accelerator pump circuit.

[@iRideuWatch]

Very nice. Thanks. I would love to watch it in slow motion as I'm only able to read and process new information at a certain rate. Perhaps I'm the only one but I'm new to understanding carbs. Thanks again.

[@pcofranc]

you can always pause the video and rewatch. Carbs are complicated but the more they are studied the easier it gets.

[@NGSVALENCIA]

I kept my mouse on the pause and made sure I got it before i continue.

[@andrewlawrence4782]

Great video, very helpful as well. Thank you very much.

[@notepon]

i dont remember actually,either white or blue.. this problem just happen after i install a component ..today when i start the engine, smoke still have and i try to setup air screw ..its work after 5 minute..disappear .thanks a lot dude for helping..;D

[@StjepanBrbot]

Excellent explanation and animation but notice of carb working ranges: from 0 to 1/4 throttle (jet pilot), from 1/4 to 3/4 throttle (needle jet and jet needle), 3/4-full throttle (main jet) and throttle valve cutaway is missing.

[@vaguincolombia]

Best explanation ever........gracias...

[@DaveWatts_ejectamenta]

I don't like CV carbs very much. Everything has to be perfect with the diaphragm and the throttle slide for it to lift perfectly. If there is any sticking on the way up the engine will stutter & there'll be a flat spot (usually IMO between 3000 and 4000 revs), if there;s sticking on the way down, the revs will stay high (until you load the engine). Aftermarket diaphragms seem not to be the same rubber material as the original and maybe don't work too well. Didn't have this hassle with the Dellorto pumpers on my old Guzzi, they just worked!

[@fiddema]

Have cv on my ktm 950. And notice a flat spot, thanks for explaining how this comes. Also i find gas response is not so quick, engine not so aggressive as I want. Or as aggressive as an 990 injection. A way to make cv carb more aggressive?
