Noone in my years of living has ever clearly explained all this to me. Thank you so much.
Right? I've rebuilt a Holly, but didn't understand what those tiny holes, or like bending the choke rod! I bet that Holly ran like crap compared to if Tony had rebuilt it.
I wont say I'm a carb master , but I'm always open to learning new stuff.
I cant stand techs who know it all, I try and be humble in my work.
Im the guy who sits back in the corner and lets everyone play themselves.
@@MrTheHillfolk im a younger dude but i know a ton of insanely obscure info. I just need to fill in the rest of the useful more common knowledge
@@ZacLowing
Back when we were teenagers, one of my buddies girlfriend's father's rebuilt his Quadrajet for his GTO.
Lol say that 10x fast.
That car was so fast to begin with , he didnt notice that her father flipped that little lever to lock out the secondaries for months 😂😂
To have some fun, take tossed away mower to your garage or shade tree. Hook up a tank of water to it (it's junk after all). Take a compressed air nozzle and shoot the air through the carb. You can use the throttle from idle and up wide open throttle. Will be able to see idle circuit, transition circuit(s), and all points up to WOT (wide open throttle).
The power valve is something to economize your car. Same with the accelerator pump. These two items economize the engine for various load conditions. But would you pay an extra $65-150 for a push or riding mower to save fuel on something you use 13-27 times a year for a couple of hours maximum run time?
My Unca from the toolbox made it easier for everyone to understand.
BTW, I reckon you could reverse a shop vac and blow through the carb with that. Just for the love of life and limb, use water instead of something combustible!!!!!!!!!!
And now it all makes sense... Almost 30 min without a cig too! Impressive!
About 90 mins and the shakes start happening , hes got time yet.
@@MrTheHillfolk I think after about 8 or 10 minutes he should have a couple of puffs, it will calm him down a little.

Yea dont work on the smallest part of a carb without taking a break first
I was smoke free for an entire day almost until I read your comment. "TRIGGERED" Thx LoL.
Uh
Not gonna lie, I'm a younger guy. I have an older friend who works on my carbs lol. He's the carb whisperer. Thanks for this. I just want to tell you that I am pretty thankful to have your videos sir. I was honestly to afraid to tear down an engine that's been in my garage for years. I figured I'd get stuck on something or break something not knowing what to do, and then I wouldn't have anybody to help me if I messed up. I saw your video literally used it as a tutorial. I don't know what the hell I had been so worried about. I guess that's my adhd kicking in lol. I'm actually because of you Tony, going to rebuild the original motor for my barracuda. I'm doing it. Thank you sir. I really mean that. Your channel has done more to get me back out into the garage than anything in my life! I'm constantly tinkering now, I'm always looking for parts and motors for stuff lol.
Awesome, Korri! You, are why we do this stuff
That is great, Korri! First time I rebuilt my bike ( 82 Yamaha Seca) I was scared as crap( I bent a valve when I missed 2nd) I bought a new head and did it in my bedroom with manuals ( no internet in 82) she fired right up! It's gonna happen for you too, and you wont stop smiling for a year!
How’s the Barracuda?!
Here I thought I only watched for 5 minutes, without realizing that I'd watched the entire video! That's how you distinguish a great channel from a lesser one, the great channel keeps the audience captivated no matter the topic! Great video as always!
I thought exactly the same thing! But then I couldn't stop watching - like you. LOL
Wow that's deep bro !
Uncle Tonys' gift. He love to teach too!!
I felt the same way!
I cancel my TV channels. This channel is better than all the motor channels ... really good work Tony!
👍👍👍
Hasses Garage agreed
been waiting til july so I could watch my fav original top gear one more time,
roadkill ect has been losing touch with their origins more-so recently
F**k tv.
I havent turned mine on in about 6 months now.
UA-cam is my entertainment.
I need to call them and cancel that.
Stupid triple play , 150$ a month and you cancel 1 part and its still a rip to keep 2, probably 120 a month still.
I dont use the land line and the answering machine is packed.
I should ditch that too, im not sure yet.
did the same
Same here, haven’t had cable in a few years, have Netflix but watch UA-cam more 😁
The mark of knowledge of a subject is the ability to explain it well to others. Great job Tony.
I was raised on carburetors, all my dad's cars had carburetors , my first car had a carburetor. I used to adjust them all the time , "the chock the jets the idle screw ect ! " I used to be like uncle Tony I used to have extra parts in the trunk of my car because I was raised to not depend on nobody and to always be prepared. Like 1 time we got stranded on the side of the highway 41(CA) because we were going to pismo beach and my distributor was acting up , but lucky for me I had a spare in my trunk I put it on and I was on my way , it took less than 20 minutes to get on the road again! Thanks for another good video uncle tony!
in the Commonwealth, this man would receive a knighthood
baz770 In the Commonwealth, they would have expected him to explain the workings of an SU carburetor, which operates in a somewhat different (wacky) manner but is beloved of Brit car geeks...
Fuel Injection is great because it has made used carburetors cheap. Luv my quadrajets and afb's
Very informative mate! Your video's are getting better and better! Please don't change your format!
Tony- I love this shit! Brings me back to my youth... back in the 80's I drilled three holes in my old Nikki four barrel (oem) float bowl lid on my Mazda Wankle/Rotary truck (REPU). I soldered bent copper tubes into it about 6" long- one to the left, one straight up, one to the right as a fuel "escape buffer" for hard cornering. these ran up into the air filter housing and gave the fuel a place to go rather than flooding me out in autocross/hard cornering..(removed all emissions controls) It was a pretty cool modification. I also made up a simple linkage to convert it's vacuum secondaries to manual and removed the choke. That truck was scary fast!
Carbs where the first thing I learned to rebuild 😊 and after that a 200r4 transmission. Efi seamed complicated but really it was not, so yeah I'm 26 now and i do like my tech 😅
Truly a UA-cam treasure. Thank you for this amazing video. I remember when I was a kid, people used to joke carburetor is Italian for leave it alone
Good simple explanation of the carb. I have in my time bought cars cheap because of bad carbs and the people just wanted to get rid of car. So that's where a bad carb is a good carb.lol
Passing on your knowledge.
Very respectable.
I have been told i have a knack for carburetors. I just think nobody else wants to fix em.
been playing with carbs for 40 years, this is the best explanation I have seen of how they actually work. Nice to get back to the basics, helps with troubleshooting and tuning.
I wanted to thank you for this video, I'm in the younger crowd that understands fuel injection but never touched a carb in my life. I work in an auto parts store and this will help me help people with older cars better
Love these more technical episodes. Your way of explaining engineering concepts is incredibly clear and easy to grasp.
Gerry E Your*
@@jumpinjojo fixed
Gerry E You’re welcome.
@@jumpinjojo Hey Joe, it's me, your uncle Lenny. Keep on lifting.
This video helped me fill in the gaps of my carb knowledge. 30 minutes of video just leaves you wanting more!
When the engine is turning, air is sucked into the intake manifold. The carb sits on top with a fuel line connected. In its most basic form, a carburetor is a mechanical atomizer.
Great explanation Unc.
I remember reading a story where a guy said he had the carburetor off of his Cadillac 500 and he had to bump the engine over for some reason... mechanical fuel pump start pumping Fuel and dumped it in the intake, and it started and ran and took off to a million RPMs....not sure if its true, probably a wifes tale but sounds good....
But there's simply no way it can atomize more accurately than a fuel injector
Thank you. I have owned several carbureted vehicles, including my current 1985 Dodge Ram B250 van. Many shops won't touch a carburetor these days.
I feel you, mechanics who know carbs are a dying breed, so the only realistic option is to learn fixing and adjusting them yourself.
Thanks for another good educational vid Uncle Tony! I'm only 27 but I'm a die hard carb guy and it grinds my gears so bad when people list instant startups, instant throttle response and good gas mileage as advantages specific only to fuel injection. My 68 Satellite, 73 Mustang, 75 F100 and 84 Trans Am all start up immediately! Your fingers aren't even on the switch for half a second before they fire up! The cold starts and throttle response on my Satellite are the kind of instant action modern fuelie guys are chasing when they punch around on a laptop.
The Satellite also gets amazing gas mileage for a 50+ year old car with a carbureted cast iron V8. I haven't checked the MPG since I changed the motor and rear gear but I used to get just over 25 MPG on the highway with the same carb back when I had a 273/2.76 combo.
When you can get better cold starts, better throttle response, better overall power, better reliability/maintainability and comparable fuel economy for roughly a fourth of what an EFI system costs the answer is clear!
This video really takes the mystery out of carburetors. I remember being overwhelmed the first time I pulled the Mikunis off of my FZ1. I spent hours learning the ins and outs of those things, mostly by screwing things up, like misplacing the starters and mains. Lessons learned, skills developed, and now it's a breeze. I have owned this particular bike since about 2008, and don't think I will switch to fuel injected bikes any time soon. The carbs may leave you with mileage/power fluctuations at different altitudes, but maintenance and upkeep is much cheaper, and easier. And as Uncle Tony stated, MOAR POWER!
As a tech it's been over 20 years since I've sat through a basic carb class. Well done and thanks for the refresher.
I like this old school tech series , I know the new stuff really well as a pcm programmer. Just dont understand analog stuff. You nailed it.
I heard a kid recently describe it as "steampunk", as it's an analog, mechanical system that does an intricate job accurately - and it's full of little brass parts. :-)
Please dont let them put a microchip in a broom, I dont think its been done yet and its not needed from where I stand.
My first carbureted vehicle? A 1977 29 ft Bayliner with not one, but two 305 SBC's, and Carter BBD's! Won it at the "Abandoned boats sale" over at the moorage. This vid is a blessing. I'm gonna need it, this boat is a time capsule. Stuck in 1977 w/ all the 70's funky upholstry that hasn't been started in a few years. Fascinating stuff! As a space millenial, my first instinct when I see a carb is to poke it with a stick, but after watching your vids, I'm ready to do things like, set float height and stick steel bristles into idle jets! Thanks to you, i'll be ripping down the river in my shag water craft in no time!
Years ago I bought a NAPA rebuild kit for Dad's 225 slant-six Dodge van for $16. It had a single-barrel Carter carb. Included were instructions. I followed the instructions carefully (I substituted using my thumb as a vacuum source for the dashpots - push in dashpot, hold thumb over vac port). I bent all the rods and measured everything to get things to exact specs. A few hours later I had a perfect-running van that automatically kicked down from each step of hi-idle. I was SHOCKED! For years, Dad took the van to several Dodge dealers who played around and even put 2 new factory carbs on it and could not get it right - all problems were related to the electric servo/stepper motor operated choke. I think it was also the moment I decided that I would never take another car to a dealer to get fixed. It amazed me how little even the dealer mechs knew about carbs. Thanks for yet another terrific video!
I'm a retired mechanic. Tony is the best automotive teacher I've ever seen. Love the info.
I adjust my 650 holley with the manual choke and vacuum secondarys with a large ball peen hammer. Kicking my self for not keeping the Quadratoilet.
I've been fooling with carbs 60 years. I have a hard time explaining to others how they really work. You clearly explained it all, without over-complicating it into a big messy engineering essay.
You have rare skills for instructing average people who are not gearheads like we are! Very well-done, once again, Uncle Tony! Thank you!
Yo Uncle T, great stuff. I’ve been an ASE Tech for 10 years and this was the first time I actually understood what all that analog witchcraft did. Everything in tech school was EFI and and scan tools. Only one instructor had even worked on analog professionally. Thanks Uncle Tony.
Great educational video uncle Tony. Well explained for younger generation to understand. My son is 18 and has no intrest in efi on his muscle cars. He can make a jet change at the track in like 5 minutes. Lol. Makes me proud.
This is awesome. I have been given a bunch of cars and engines, because people thought they wher worn out or broken. I rebuilt the carbs on em, and they where fine..
Uncle Tony's videos are so good that i give them a like while the add is still playing lol thanks for the info, keep it up brother!!
Thank you so much sir for sharing your extensive knowledge with us and explaining it in such an interesting and easily to understand manner. You rock!
Perfect. A 10,000 ft view of the basic subsystems, what they do and loosely speaking, how they do it. Now I'm competent enough to ask Google the right questions. Again, perfect. Thanks Tony.
Thanks for making this video man! I’m a mechanic for Subaru and I’ve been doing engines for awhile now and like you said I just hadn’t had to understand the carb. Thanks for making a good easy to understand video about carbs!
When I was in high school 40+ years ago I rebuilt quite a few carbs for others. Mainly Rochesters but there were others in the mix. Used to charge $10-$15 depending on the model.
THIS video explains all the basics and would have come in handy 'back in the day'.
I love the t-shirt idea. Maybe do a series of them with different distinctive carburetors - Weber, S.U., Holley 4 bbl, Carter, etc., maybe even an old Hilborn mechanical fuel injection system - with the legend "I am the computer" on the bottom.
A Kingston , Marvel, eeew and a FISH !
i figured out carburetors when i got an interest in old school motorcycles when I was 17, while I am not fantastic at it I have torn apart a lot of them and have been able to successfully get things running really well. Glad to have it explained this way and reinforce what i know and give me other info that I did not know. Great channel
I'm in my 50s, been into things mechanical since I was a little kid in the 70s. My first carburetors were on Briggs and Tecumseh engines on lawn mowers and later mini bikes and go karts. In 1980 I started high school at a state Tech/Vocational school and I enrolled in the automotive trades course. My auto shop teacher was old school, mean, demanding and sarcastic and that's what made him so great. He explained carburetors about the same as this but there was one more thing he taught us. Carburetors operate on pressure differentials. Inside the throttle bores are what's called a venturi. What that is, is where the main fuel discharge is, the throttle bores neck down a little smaller than the rest of the throttle bore. As the air moves through the venturi, it speeds up and that creates a low pressure, or vacuum within the venturi and that vacuum is what draws the fuel out of the fuel bowl through the main power system or circuit as he called it. Basically the pressure within the venturi is lower than atmospheric pressure so the atmospheric pressure actually pushes the fuel through the main circuit and out of the discharge in the booster.
Nice to see an old school tech making it on UA-cam. At 53 I've finally started mine. Keep inspiring. Thanks
Tony you gave the most comprehensive and detailed explanation of carb operation! Much more detailed than any pro instructor! Oh yeah and in words any beginner could understand...I've been in the business for 40 years and feel you could teach some of these new school motorheads where us old school dudes got our talents!!!
Have 16 thermoquads in the shed.
I refuse to put efi on my old mopars.
A properly tuned carb is just about as good as efi.
It’s cheaper. Easier. Less complex and at WOT they can make more powerthan efi.
Another great video, Uncle.
Some ECMs -can- be hacked for performance, notwithstanding emission control standards...
The Thermoquad was the best standard factory 4bbl ever offered for performance, AND economy.
That's why I'm such a fan of the Spread bore carbs. Small sensitive primaries for milage and large secondaries for power.
Never heard explained so clearly awesome job!
Thanks uncle Tony!!! This was very informative! This helped me understand what’s going in my Carb .
OBD? How about O.S.D. (Old School Diagnostics) where, as you say, "I am the computer!"
I've been working on carbs my whole life, college trained way back when. I still learn something new every time I'm into one!
57 years old now, been tinkering with vehicles and their components for forty years, and I learn something new with practically every video. Thanks Tony!
Thanks Tony, from your insomniacs club! Also as a fellow smoker may I say that I am deeply impressed by you getting through the whole lesson without a cig. You have to have be a smoker or former smoker to know how difficult this is. Just ask me I have quit dozens of times. 👍☮️
He's made it through the crucial first few days.
Thanks Uncle Tony!!! I thought you did a great job and I understand now. My uncle owned and operated a salvage yard and Repair Garage for 40 years. I'm 55 now but when I was 16 I had a 70 duster with a 340 and a Carter 4-barrel. My uncle and I were talking one day and being a young kid I was telling him how I wanted to put a holly on this because everybody told me that Holly was the best. he told me well you can do that but he said that Carter four-barrel is one of the most simplest and easiest carbs to work on and they will perform just as well as a holly. So I wound up buying an accelerator pump because that was the problem and we changed it and that car became alive again that 70 duster was the fastest car in town I miss that car... Of course being 16 and the first car being a duster made me a Mopar fanatic ever since keep up the good work I'm glad to see they're still guys out there like you!!! Jim.
Thank you so much! Im 38 and finally own my first classic Mopar. Have the Carter AFB 625 CFM 4BBL. This is the first vehicle i've ever owned that is carbed..
jeez 3:26 am, but hey at least it’s Uncle Tony!
You really brought back some memories with this one. My first car had a 318 with a 2 barrel, which looked identical to the one you took apart, and I was always having to mess with that thing. It didn't help that my gas tank had rust in it that went right past the fuel filter and would get in between the needle and seat. That was over 30 years ago.
To me, carburetors are voodoo and black magic. You must be a wizard to work on them. I suppose it's because my father did not have the patience to work on them. Thank you for posting this great video. You have helped with another of my "unsolved mysteries of the Universe." "Internal combustion happiness happens" I started laughing and woke up Bambi the Chihuahua and disturbed the sleeping cats. LOL
Another informative and very accurate description of how a carby works. Well done Tony, keep em coming .
I have watched about a 100 of your videos and now I am here to pay homage to you. I have finally figured out the problem with a WWC 2 barrel Stromberg carburetor that I believe is original to the 1967 Chevrolet C70 gasoline powered dump truck I have owned since 1990. The dump truck has a GMC big block 401 Magnum V6. It says so on an ID block on the right side of the engine front of the cylinder head area. This dump truck only has about 80,000 miles on it for being 54 years old. I can tell you that this truck has always made me feel uncomfortable when ever I licensed it to drive it on the road because it hesitated on acceleration. But we humans adapt and continue to drive it even though something is obviously wrong. Maybe 20 years ago I put a rebuild kit on this WWC carb. The instructions that come in the rebuild box are very poor. I was always suspect of the accelerator pump. This new kit I bought from Walker products had a very illegible blowup of all the parts. I watched your video and got a better understanding of the idle system, high speed circuits, port manifold vacuum, manifold vacuum, and accelerator pump circuit. I FOUND OUT THE CARBURETOR WAS DEFECTIVE FROM THE FACTORY. This truck was built at the Pontiac GMC factory in 1967. The manufacturer of the Stromberg WWC carburetor is located in Elmira, NY. The defect I found was in the air horn venturi part that sprays the fuel down the throat of the carburetor. At the bottom of the accelerator pump is a BB size ball to act as a check valve. When the accelerator plunger moves down the check ball seals the plunger chamber and the fuel is forced through another passage to the venturi air horn circuit. A smaller check ball resides in the air horn . When I assembled the carb and installed it fuel never sprayed through the venturi horn and into the throat. It oozed out of another hole that had been covered up with maybe JB Weld. I had removed the JB Weld and the fuel just oozed out of that hole. I threaded the hole with a 6 X 32 tap and put a little screw with a little flat washer in the hole. After doing that I could not install the accelerator pump. It was hydraulically locked because I left the fuel in it and in the fuel bowl. I removed the 3 screws that hold the air horn venturi in place and examined the air horn venturi. I found out that no hole existed to allow the fuel to get into a chamber that has the holes for spraying into the throat of the carburetor. I removed the little 6 X 32 screw I installed. I drilled a 1/32 hole from the tiny BB area into the venturi chamber that sprays into the throat. Now I found another problem that the parts blowup does not show. On top of the carb by the hold down rod is a metering type hollow thread screw. Fuel was being pumped up this hollow screw when the accelerator pump was activated. I had an extra small BB from the carb kit. I ended up putting a small spring for the BB to set on in the metering hole. This ball acts like a check valve keeping fuel from spraying out of top of carb when accelerator pump is depressed. I finally got a nice stream of fuel spraying down the throat of the carburetor. I was up till 2 am outside in 29 degree weather praying to God that the big old V6 Magnum would not catch fire as I messed with the timing. Huge balls of flame where lighting up while I cranked the engine. Gas was dripping everywhere. I know it was not the float. I had messed with the 90 degree elbow brass fitting so much it developed a crack in it. I dug threw all my brass fittings and found a suitable replacement. Finally the engine started but it sounded like it was running on half the cylinders. But it idled at about 700 RPM. I pulled plug wires and found a dead number 2. I cleaned the spark plug and still no power from that cylinder. I pulled the valve cover and the intake push rod looked like a pretzel. This engine has solid lifters. I found Melling push rods MPR121 and am waiting for the parts. I believe all the back firing through the carb bent 2 intake push rods. I still have to check the drivers side. I can't believe I fixed a 54 year old manufacture defect. Thanks Tony. I think I am older than you so its hard to say uncle. I need this dump truck to work real bad.
Carburetion Theory 102
This would have been the best class in the Auto Tech Program if taught by Professor Tony.
I know this is a few years old but man I’m so glad I came across your channel. Literally have done the things you explained in this video to my old carter carburetor and now my 65 bonneville is running amazing. Appreciate you giving actual information
You nailed it great job on the explanation Tony THANK YOU SO MUCH!
Thanks Uncle Tony for taking me back 45 years... I rebuilt a Carter BBD open vent for my '64 Plymouth a dozen times through my early years, and that later 70s vapor bowl version you used in your demonstration reminds me so much of that. Those days were so good for encouraging folks to use their brains for car repair and upkeep, rather than nowadays' just jumping in, turning a key, and going.
Absolutely the best carb explanation ever. Super simple yet so complicated.
Tony is old school. Thanks god there are still people like him. I grew up in 80s an miss the simpler times
Greetings from Australia. Great Video, hope there are a lot more of these on other topics as well.
Internal combustion happiness happens.....gotta love it! I appreciate how he has no written script he just goes through and if he has to turn around and start with another concept, that’s exactly what he does :-) it’s like you’re right in the shop there with him and he’s just chatting with you.
Some great explanations on carburetor functions, thank you. I think another reason for fuel injection is reducing exhaust emissions. The formula for the perfect air/fuel mixture becomes so complex when you are trying to reduce emissions more and more, that the "analog" mechanical computer which is a carburetor (metering rods, thermostatic choke control, vacuum choke control, accelerator pump, etc) can no longer cope. Controlling air/fuel mixture becomes a perfect candidate for computer control, which can handle complexity and non-linearity much more easily. Also, with oxygen sensors in the exhaust pipes, fuel injection becomes a "closed loop" system, meaning the computer gets feedback from the oxygen sensors on how well it's doing its air/fuel mixture calculations. Carburetors are "open loop" because there is no feedback whether it mixture is optimal. Of course, pollution thresholds were much higher in the 1960s.
Guys like him, and like my dad, we should learn as much as we can from them one day they'll be gone, and all their knowledge, I appreciate their time to explain things. Plus he's a mopar guys
Couple of things I didn't know, thanks.
"I am the computer". YES! Be your own computer as much as possible in life! --- Great thing about carb rebuild kits is they come w/exploded view instructions exactly like a model car kit. So one can easily glide from model building as a kid right into CARBS w/a little help from Big Tony's no bull videos. I always learn something from each video. THANK YOU!
This is probably the most easily understood video I have seen explaining the good old carb and how it works. Great job Tony!
Great Video.
Strange how a relatively simple device that can be traced to the end of the Steam Era can really confuse people.
Good systematic explanation.
I have shared this video with friends so they can help others deal with the fear and mystery surrounding carburetors.
Thanks!
Excellent video Uncle Tony, excellent refresher for us that grew up with the carburetor. Still love and use them today in my cars. Looking forward to the next great words of wisdom!!
The Man - The Myth - The Legend!!! He Hath De mystified the Almighty Carburetor!!! Love your explanations. Even a Fool like me can grasp the theory. I am in thy debt Sir.
We are all in his debt
Uncle Tony, I'm 33, never subscribed to a youtuber channel till yours. I've never commented on UA-cam until now. You are the reincarnation of my dad, that man is the reason I love old school cars. I love what you do, and how you're doing it. Wife went behind my back, got me a T- shirt and stickers today!!! Keep it up man! My best regards to uncle Cathy!!
I am a Hd truck mechanic. I work on trucks that have some times 7 or more computers on board. It is so nice going back to the basics. I just got a 1971 duster twister with a 318. I love the ease of working on it. And just enjoy it. I like the fact you are on here and giving good tech and every time witch you I learn something. No mechanic knows it all but we can all learn from each other. Thanks for your for your time and effort.
Yes! I've rebuilt many carburetors before but NEVER understood what the heck was going on in there...Now it makes sense, clear....concise and to the point in plain English. Thanks Tony!
Thank you. I'm restoring my first car (76 D100). Swapped the motor with a 66 slant w/ a Carter single and points. Truck's been sitting since I left for the service in 06. With all this nonsense with the overblown seasonal flu, I've had a lot of extra time to work on her. I've been watching all your vids on the slant. Loved the 'Understanding the Slant Six' video. You remind me of my childhood mentor who taught me most of what I know.
I learned about the fuel metering seat, where the idle passages are, how to adjust the idle, and the choke release. Thank you so much! I'll be rebuilding the 76 slant with HEI for performance (nothing crazy) and then I'll rebuild the 66 slant.
I'm going to watch this video several more times so I can imbed in my mind all the things that I should have known 15 years ago. Thank you very very much.
You know it's car learnin' time when the glasses are on
Simple, clear information delivered at a nice speed with great demonstration. The best explanation for carb workings I’ve seen or heard. Nicely done.
I am a complete Newb to getting into my engine. I just bought a 72 Super Beetle and it has been a lifelong dream to work on cars. People talk so fast and skip basic knowledge and I am floundering. This is the first video which has actual explained so clearly that I think I an do this. Thanks so much!!!!!!!!
Absolutely awesome. Thank you for sharing your knowledge. Your teaching ability is top notch. Keep em coming!
I went to get my A/P license years ago without a lot of knowledge going in. All the best instructors were old school car guys... just like you. Thank you for doing what you do, so skillfully and thoughtfully, you’re a nice guy too, I can tell. All the best.
Holy hell dude, you know some s**t. "Phenolic resins" (synthetic plastics) DANG. Now I finally understand why my 1970 307 2-barrel had that maddening acceleration flat spot -- the accelerator pump. Only too late, that car is 26 years gone.
An outstanding tutorial! Time for me to rewatch UTG's "Understanding the Thermoquad" video with a new found appreciation.
Thanks Uncle Tony, carbs have never been explained so clearly to me before. Every one needs a Uncle Tony.
Brings back memories of rebuilding my quadrajet 25 years ago. Wish they had UA-cam back then, had to follow a Chilton manual to get r done. Great video 👍
Sat down with my first cup and *BOOM!!!*, I'm right back in High School Auto Shop class! Outstanding explanation, my friend.
I’m not even really a car guy and I look forward to your videos every day. They are the first ones I watch. Thanks.
I love my 79 d50 pickup I can get in that truck no matter what and she fires right up no ifs ans or buts,,, great video brother keep up the great work
Thank you, Uncle Tony. This was very helpful!
I can see in the way you talk that you just have so much knowledge that you want to spew out at once lol. Incredibly informative and you are one hell of a teacher 👍👍great work, love the videos, keep em coming
I learned carbs from mowers, then my 85 S10, and this and your channel has helped me so much with my rebuild. I adjusted the float too much and it flooded then stalled, but my first rebuild technically went successful. Thank you!
I’ve always preferred to work on a carburetor over EFI. Learned it at age 16 when I bought my numbers matching 61 Impala. I was proud to have that car running like a top..
You sold it, didn't you.
Ronald van Kemenade sure did. Worst decision I’ve ever made. I tried to find it and buy it back a few years ago, after some digging I found out it had a frame off restoration and it’s now a show car in GA.
@@hommeldavid Same here. 63 Impala convertible SS. White + red int. Prettiest car I ever had. Only thing it lacked was a 409. Sold it planning on getting a better one, but went for a more sensible 80's wagon instead. Also V8 rwd, but not even half the fun.
Ronald van Kemenade my dream car is a 63 convertible. Found a 64 SS with its original 409 and 4 on the floor rotting in a field once, guy would not sell. I bugged him for about a year offering him more money every time. It’s sad when people would rather let something rot instead of letting someone fix it up.
David Hommel Over 25-30 years I watched a 58 impala convertible rot and rust into the ground because the owner was planning to restore it himself. It ended up leaving his yard in a scrap dumpster in several pieces. Every time they tried to lift or move it, it broke again.
Great job. Trying to convince my 2 sons that carbs work fine. One has a 72 Toyota HiLux with a Weber and the other is a 81 AMC Eagle with a FoMoCo Motorcraft 2 BBL.
Tony is spot on - the carb float bowl, floats and needle valves work on the exact same principle as a toilet tank. My '69 AMX flooded once and after tearing down the Edelbrock 1405, I found the problem. One of the floats was full of gasoline, allowing the needle valve to stay open.
Great work! I love how you are able to simply come up with the perfect words to on the fly to explain very technical systems. That is a gift my friend and it makes watching your content easy to get!
I was born in 84 and as a kid I would watch my dad work on his 49 Ford Pickup or his 68 Pontiac Firebird. And as a teenager my friends and I would tinker with EFI 4 cylinders (VW, Honda's) as they were the type of cars available to us.
My grandfather passed away a couple years back and he had a 64 Thunderbird sitting in a shed that was not running and am still in the process of getting it road worthy. I am having a lot of fun with diagnosing all the problems and pulling it apart to see what what is failing.
I have rebuilt the carburetor, replaced starter cyliniod, fuel tank, mechanical fuel pump, and the brake booster is in the shop right now getting rebuilt.
The reason I am sharing all this is to let you know who is watching and why.
Your videos keep me grounded in reality to the scope and long term payoff these projects are. I am so grateful to hear your prospective on how to approach older cars and I want to acknowledge you for respecting other peoples opinion on what kind of cars and systems they are into. I think I am ready to buy a t-shirt 😏
Awesome, thank you. Matt, you are the reason we do this stuff
This made more sense than so so many other carb vids i have seen to date. Thanks man !
Thank You " Uncle Tony " ,,, The BEST Carb Function Video out there ...
Because of you I just got my 84' Dodge D100 running after it sat for atleast 4 years . I really appreciate your expertise 👍
