This vid reminded me of adjusting the mixture screws on a 383's AFB, in the early 70's. The guy is watching me, and says: "One of those is for gas, and the other is the air,..... right?" LOL!

A wizard lives inside every carburetor.

When do you start teaching at Middle Tennessee State? Hay,, The serious stuff, I am glad you and Kathy are safe and the offer you gave to help others is the actions of people with Class.. Keep being who you are.

We need more people like you on the internet. Fountain of knowledge, always gets straight to the point, some great stories too.

you should also tell ppl new to this..dont make any adjustments other then the choke on a cold motor...if you are going to play with the air/fuel screws...only do this on a warmed up motor

For clean idle passages 3rd electric guitar string is perfect.

Sitting here in school , doing a refresher. As a kid I wasn't making squat working in a garage , so I went to tech school. One of the teachers was a little like Uncle Tony, the way he taught and showed examples. And we learned a boatload from him and I'm grateful for that.

Something ive always kept with me when riding motorcycles....actually all the way back to when I was a kid and rode minibikes/dirtbikes then scooters then motorcycles..... is a the paper twisty ties. The kind that have a wire in themThe ones that come with garbage bags or bread. Even the ones that are flat with plastic on them. As ling as they have a wire in them. Id wrap a couple on my key or keychain or throw them in a compartment somewhere. Im a smoker so I always have a ligjter with me. If my carb starts giving me trouble I can just pull it apart. Burn the paper/plastic off the twisty and use it to clean out any orifice in a carburetor. Clean the jets, passage ways, holes, anything. If the hole it much bigger then the twisty wire I just put a bunch of kinks in the wire, by bending it around then run it in and out of the hole. Has always worked like a charm.

I love these carb videos.im learning lots

Carb chucking should be an Olympic Event !!

Boy do I miss my old E-58 code 360 Thermoquad equiped Road-Runner, what a sound that Carb had...

I was fortunate enough to learn about transition slots and idle air bleeds and carb " circuits" from older mechanics when i first started out as a professional mechanic. Vacuum signal is vital to proper idle and overall carb perforformance ive been taught. Great channel love this stuff

Back when I was learning this stuff, google didn't exist. Worse, it wasn't my "project car" or something like that, it was my damn car. Thankfully, they really aren't that complicated, but they are very mechanical.

Thank you for covering all of this old stuff again, I need a refresher because I'm getting all of my old cars back out and running again for the summer so I have ten carburetors to clean up and set up!

The more and more of your videos I watch really boosts my confidence on rebuilding an engine. I have a 283 Chevy in mind it’s these small things that help. Getting a car to just idle is something I’m sure tons of guys struggle with. You make it simple thankful for dudes like uncle tony. I never had an uncle tony before.

Thank you for a direct and to the point discussion of one part of the carburetor. This is an excellent way to discuss it, one circuit at a time. It may take a while to learn all the workings, but I get a chance to absorb what you said and I don't get bored with a long video. Thanks for the lesson.

Thanks to your last video I figured out the rough idle when my Fury was cold. The choke pull off that I replaced about 5 years ago due to a similar cold start issue was the culprit. Put in a new one I had laying around and it’s running great again. Thanks Uncle Tony! You saved me a lot of wasted time and possibly money. Cheers 🍻

Thanks for the video Uncle Tony. When you talk about it step by step like that you can see all the different systems to make the carb function. So sophisticated in a compact design.

Great advice Tony, the best way to fix something is to start by learning how it works.

Excellent video! I’ve never been afraid to rip a carburetor apart and clean it out. It’s well worth doing

Tony is a great teacher and full of common sense. Tony's strength is not only his amazing knowledge, it is also the way he explains it. I worked at car dealers from the 1960's up to 2010. There was no internet then, so when their was a problem that very few master techs at dealers could figure out, the factory would send a very technical engineer to explain the problem and how to repair it. The problem with that was most of us didn't take courses in engineering to fully understand what he was saying. Tony would be the perfect person for the factory to send to explain technical problems and how to overcome them. Just one more thing about today's auto engineers. They need to have them work for 1 year doing repairs on today's cars. They will see how "easy" it it to repair what they designed.

Its worth mentioning the dwell and timing (in that order) has to be correct before you try to get the carb/idle adjustments right.

Understanding the universal basics for ANY fuel delivery device is essential. Fine job explaining the idle and transfer holes and why the mixture screws / holes are not fed from the bottom of a float bowl (s) as one would expect. There is a trap in the circuitry for the mixture adjust, or like a plumbing pipe trap and vent for your kitchen sink drain, there is an air bleed (vent) hole somewhere in the path between the fuel bowl source and the mixture screw all depending on manufacturer specifications. Glad you mentioned the leaded over (manufacturer drill hole) with the six cylinder carb.

Uncle Tony, as always a great wealth of info. Thanks for taking the time to share your experience on stuff especially carburetors when the world is pushing fuel injection conversions! An amateur hotrodder like me loves the plain, get to the point info you share on here. I think if regular folks knew some more about carb tune basics, we’d be cool with not throwing cash over ass at EFI kits. Really don’t want too.

I gotta watch that carb fly just one more time. I'm glad it sounded like a soft landing. Thank you Sir

I'm so glad I found your channel! Thank you so much for explaining this to me like I'm five years old!! You sir are a great help to me!

I'm an old "project wrencher"... glad to see these videos...great refresher for me. Just rebuilt my Holley tonight...mount it on the 76 Vette tomorrow. Also..just watched your vacuum tuning vid.... damn glad I kept ALL my old school tuning equipment and tools..from when I was a kid, hot rodding my 70 Cyclone. Got yourself a new subscriber !

Watching your videos totally boosts my confidence to tackle some of the old beaters we have kicking around here.

Doubt you'll ever see this as this video has been out a while, but Thank You! I was out driving my slant and started losing idle. Checked for vac leaks (none) then pulled the carb (1920) and found what looked like a tiny bit of material hanging out of the tube end you can see below the lead plug. Blew it out with air (no lead removal luckily) and she runs great again. Thanks again for all the useful everyday info you put online

Uncle Tony is the only reason I can get to work with my old Mopar... Thank you for all you do.

Carbs- ain't nothin' a wire can't fix..... EFI- every wire has to be fixed!

Man i passed out watching this yesterday and then had a dream I was arguing with you and Kathy over Everly Brother's songs.. out there

ive never ever had to rebuild or take apart one of these kind of carbs but i like the info u give man you know alot of knowledge. ive said it once before but you can help a decent mechanic to understand things way easyer.

I needed this, thanks Tony. It's no bs videos like this that compelled me to subscribe.

I daily drive a 78 ford f100. I love the simple carb set up . I'm also an ASE certified technician for over 20 years now. I can't tell you how many carburetor rebuilds I've done over the years .

Wire brush remnants do great; I used guitar strings. Any small gauge music wire works well for fishing through carb passages - super strong yet flexible. Many a time I sat down and wound up playing a five string guitar.

Good point my k10 have a 4 burrell carburetor. We don't have people like you. I see your passion for the engines or carburetor 👏👏👏thanks uncle Tony

Thank you so much for all this knowledge you are passing on.

For cleaning up the small passages on any carb, I use a Tip Cleaner set, for cleaning cutting torches. They come in different sizes, & have lil ridges on them, for good cleaning. Another great video Uncle Tony, hope this lil "Tip" helps! !

Man, I remember learning carbs on 4 wheeler. Mikuni's and such. Then my first Edelbrock. Learned really quickly about vacuum leaks. Then the 'Holly' quirks. All required patients that I didn't possess. Good stuff!

I had one of those blasted one barrel Holly’s on my 69 Valiant with that pressed plug missing. A piece of rubber a dime and a toothpick made it run. Don’t forget the ball bearing check valve inside. I learned a lot from that old four door. I prefer the Carter two barrel, it just runs better. “In my opinion “. All this taught me how to make do and what it takes to get things running. A couple of important lessons here, do your homework and never ever give up. Thank you Uncle Tony.

As a young buck at 19 just getting into carbs, you have really helped me with understanding how to tune them and what their quirks are. Thanks a lot😃

Best thing to do is just start taking stuff apart - My first time working on Carbs was on a V4 street bike - what a complicated mess of mechanisms and springs linking all four together. It was definitely a challenge to get them all apart, cleaned, bench synced and reinstalled again. I learned a lot in that process. Being a young guy I had to learn a lot of my dad and a few of his buddy’s. Those old guys know a lot of stuff and most are happy to share what they’ve learned over the years.

I luv these carb videos, thank u uncle tony and uncle Kathy

I had the same problem once, good thing I figured it out! The problem I had with an edelbrock that costed me one engine and almost 2 engines, was a lean condition on the passenger side causing insane detonation, I checked fuel distribution in the bowls, even staggered metering rods and jets, to try to compensate, rebuilt it several times, tried different floats levels. I never figured it out

I wish we had an uncle Tony and crew in lake city Florida. I am telling you you have been a great person helping so many people up there.

I just finished the Carter WCD carb on my 1958 Willys Sedan Delivery. The last time I rebuilt it was 1984. The new gas is just nasty. The Edelbrock (Carter AFB) that you were holding is functionally about the same. The metering rods are much easier to assemble on the AFB. I enjoy your tutorial on carbs for the EFI set. Glad to see you're all fine. I'm waiting for the Power Valve vs. Metering Rod episode. Press on.

Hey Tony David Pearson here from Texas. I don't know where you are located. But sir , I would walk across the Sahara desert with no shoes on Swim across the ocean holding my shoes above water with my hands just to shake your hand cuz you're such an intelligent person and truly God's gift to automobiles & engines.period Myself I know you have forgotten more than most people will ever know and we can take that to the bank.😂

Throwing carbs.... love it. Your getting back to your roots! Thanks unc.

Very awesome video UTG! This will help alot of people in my age group, to save some time and money on their carbs!

Good video, my automotive diet consists of lots of carbs!

Hi Uncle Tony, great great video, love the carb toss

I have seen AFB idle mixture screws tightened to the point of breaking the casting inside the throttle bores around the needle holes.

Uncle Tony, you are making this very simple and understandable, thank you!

You're my hero Tony! Hope the nadoes missed you brother man

Uncle Tony I have 3 carbureted muscle cars and I’ve never really been a carb dude knowledge wise most of my old school wrench buds aren’t either too much guess work very little help thanks to your vids I have absorbed enuff info to dial in the one troublesome carb I believe it sat too long without running my guess keep up the great vids wish I would found you years ago

Thanks for all the info you put into your videos!

You are 100% right Tony. There are so many tricks to the trade, almost insider stuff that books just don't cover.

Great video.I have no problems getting throw away mowers running...(usually carb) but I haven't had a carb vehicle since 98-99 ish.

I used to have a couple of those Holley slant sicks carbs with Pyrex float bowls on them

Good information. 1st time I realized carb spray doesn’t do much. Thanks!

These videos are slowly turning me into a carb guy from a FI guy

Great video, love the detail. I'm new to carburetor, learning with my 77 C20. Just bought a Edelbrock for my truck. Is a nightmare for me but learning on it. Just subscribed, gonna watch more eof your videos.

Thanks Tony this stuff is solid gold!!

I just love watching your videos, the knowledge you give away is so helpful to beginners like me

Most of these guys dont rebuild carbs or understand how they work. It's the same with all the small engines I work on. There is transitions in all carbs u just have to learn how they work before u work on them. Good video man, keep them coming alot of good advice even for experienced guys

Gosh do I ever appreciate your videos, you go into this stuff in the sort of detail that I personally need to understand this stuff. I find so much of the time its given in such broad generalizations where its along the lines of 'just do this trick or that' that doesn't give you the information to deal with a broad set of problems. I think I did a fairly good job regardless, but I wish I had some of this information when I was rebuilding the Quadrajet on my 88 caprice wagon (yes, of course it has the fake wood). I've been becoming very fascinated by these pneumatic control systems lately. Its something that's largely alien to my generation, at least outside of certain specialized fields like hydraulics but I'm mainly speaking of stuff based off gas pressure differentials. I mean hell, even the HVAC control systems on my Caprice are controlled via that sort of thing; partially anyways.

Never had to mess with a car carburetor but my 2 stroke dirt bike has one and after 2 years of messing with it I went to a $500 fuel injection like carburetor and it runs perfect all the time now. Well worth it for me! Tried every combination of jets and needles and it was never right. Carburetors are easy to adjust and get to run but hard to perfect it at every elevation and temperature.

I had lead caps over the idle mixture screws on my stock Carter AVS on my '69 Charger with the factory 440 single four barrel.

I can only build one kind of carburetor Quadrajet. I get the numbers off the side of the carburetor and the rebuild kit. And quick drying epoxy. A can of berrymans chemtool carburetor cleaner. The best luck I've had is with new carburetors, and taking carburetors to a professional carburetor rebuilder. It was just easier for me to throw $200 at it then it was to deal with the frustration. I'm just better at scraping up $200 then I am working on a carburetor. A good carburetor rebuilder will have a test engine on a stand. He will dial your carburetor in before he returns it to you. Another thing I never touches is automatic transmissions. Automatic transmissions require a specialized chimp. Those parts are like bolt on components to me. The failure rate on rebuilt transmissions is high. I think it's like one out of three. Sometimes it's better to just let a shop do it. That way if there's a problem I just call a tow truck. I'm 61 on old and sore. Too old to be looking stupid fucking around with something several times. That little idle circuit on the carburetors kind of like an upside-down P-trap with a vent. I'm a plumber. Excellent video Tony. Thanks again

Thanks for the video Tony! 👍

Right On Tony. Good Info For The New Guy's.

Yep. I learnt most of this from a book I had a long time ago on Holley carbs, how to rebuild and tune them.

Heres a tip for cleaning out any small passages in carburetors (automotive or small machinery). I've been using electric guitar strings. They come 6 different sizes to a pack. .008 solid wire to .042 wire wound. Great for fishing filth out of tiny passages in carbs. Dirt cheap too.

Great Video, I am sure that this will help a lot of people at some point, including myself. Thank You.

The throttle plate tip is invaluable! Uncle Tony, National Treasure!!!!

I would totally sit around the shop, drink a beer, and BS with you. You are a very smart man.

I've found a good rule of thumb, Carter or now Edlebrook carburetors are so complex that they are simple to work on, Holley carburetors are simple but are complex to work on, because I had a 750 double pumper that kept blowing out the power valve when the engine was held at 6500 rpm then dropped back to idle, I remedied the problem when I put a 725 cfm Carter Competition in its place and got better 60 ft & 1/4 mile times plus higher mpg during the runs. As of this day the guy I gave the double pumper to still cant fix the power valve problem and he owns and operates a race shop that specializes in Holley race set ups. So I just do the KISS method, Keep It Simple Silly and go with the simplistic item that's pretty easy to maintain and upkeep and it'll get you what you need!

Brilliant, free gold fellow gearheads, Thank you my man...

Me and my dad were working on tuning his carburetor and we couldnt get it to idle and it just smelled up everything. Well after trying everything, he set the idle to 40, drilled out the holes in the front butterflies a little more and it is a dream that doesnt smell / burn up your eyes. I believe the came is a 232/236 110 lsa.

Lov your show found it about a week ago been watching it ever since. Ken

Hheyyy,,, Big Tony(!), You, my friend not only are a beast with your knowledge and wisdom, but you definitely do not suck passing that knowledge along! I grew up "not wealthy" and farming, ranching, racing, repairing, etc. so I know this stuff too. Here's my take away point; I have played your video(s) to non knowledgeable people, rather than trying to explain something myself (which I am also quite capable), and the newbies have totally been able to follow you and (with only 1 or 2 clarifications from me) and you can see the light come on in their eyes! So, a big fat attaboy to you my man👍. As they say in star trek (which I do not follow); you have the con. Carry on 😎

helpful video. I have had a no idle caused by someone screwing in the needle, getting it stuck and breaking it off in the hole. just like you say. its a cleaning out the passages to get fuel flow.

Thank you for the tips!

Thank you for the video! very helpful!

Thanks tony, prayers for America's volunteers state,Tennessee, God bless.

Just got hooked on your videos.. Great info. The problem im looking to fix is to why i am leaking out of the driver side secondary shaft.. its a new to me rebuilt 1406 Edelbrock. Still trying to get it up and running

Love your videos Tony.

Thank you uncle Tony! You should be teaching in your local tech school!🙂 You make this easy to understand !

Great info...Thanks!☺

I helped a friend with a 1978 Toyota pickup a few years ago. It would idle ok, but it would not drive right. I spent about 30 minutes figuring out what each screw did on the carb. Once I knew for sure what each screw did, I started dialing in the idle better, messed with the initial timing at the distributor dialing it in at idle, then fiddled with the other mix screws to make it run better off idle with no load. We took a drive around the block, and by doing all the adjusting by ear and nose, I got his truck to actually drive much better. It was not perfect still, but it didn't try to ram him into the vehicle in front of him anymore or get him rear ended. I honestly think looking back, he had a vacuum leak somewhere that we did not find. But hell, that truck had 335,000 miles on it, and that engine was BEAT on in the time he had it (it never ran right and I am pretty sure it was run lean for the better part of a year) and while it ran like crap, mechanically it was still fine!

Holy canoli that's a lot of comments, love your videos brother. My apologies if you've tackeld this but an addendum regarding idle air bypass as it applies to the correct orientation of the primary butterflies at idle would be a great addition to this video.

Love your videos T, keep up the good work

My old 77 Econoline would kill intermittently too. It never worked for me before but I pulled and cleaned the mixture screws and blew shop air into the mixture screw holes and that did it. Edelbrock 650, I'd already opened it up and cleaned the Jets and passages to no avail, evidently I missed something so instead of disassembling it again I used the shop air trick.

I've noticed sometimes that timing, and or Vacuum advance will affect Throttle stop screw adjustment. Like if a particular combination is set up to run on manifold vacuum instead of ported, and is currently on ported, then Idle screw will usually be cranked up into the transition slots to compensate for lack of timing...

I started my apprenticeship in 1985. When I was in trade school we learned carburetors and what is now, primitive fuel injection. My final exam to get my license (Canada), it was so outdated there was a section about X frames.

awesum content !! thanks :)

Thank you youtube for recommending this

My Favorite Uncle! Love You Man!!

If there are any vacuum leaks, the engine may not idle or will miss at idle. You cannot properly adjust the carburetor with vacuum leaks. Also if RPM is too high, it’s off idle circuit and won’t adjust. Most are off idle circuit around 1100-1200 rpm. Plugged idle circuit is the most common reason for a rebuild but the most common problem now a days is choke issues. With cleaner fuels you don’t have much trouble. Accelerator pump is probably the third most common problem with carburetors. That hesitation when first hitting the throttle. I always check to be sure a good strong squirt comes out when snapping the throttle engine off. I have rebuilt more carburetors in my life than I wish to admit to. Fuel injection is so easy and easy to set when the engine has been upgraded such as a larger cam etc. I still enjoy rebuilding carburetors even today. I teach my son the older cars along with the new ones. I’m working on a LT1 right now with him and he’s having trouble with the Optispark system which I myself had to educate myself about it for I never had any prior experience with it. Have a great day/weekend.
