I've said it before and I'll say it 100 times yet....I wish I had these videos when I was 16.
Yep! Same here. Now I've learned the basics over time, lol. I still watch these though. Because not only do I learn a new thing here or there, but it also reminds me of things I forgot. Because as of late I havent had to tinker as much with the carbs because of the newer fuel injection in the driveway. Problem is, I still have my old stuff I like to play with. But since playing with tham has become rarer. I forget a lot of the little things.
No kidding. We had no such resources then.
Shit, I wish I had been allowed to drive at 16.....
@@tarstarkusz when I started driving, I wasn't "allowed". I did it because I had to. It came with the territory, it was part of my job. So was fixing the old things I drove.

I'm 61 years old and 21 at heart. You are one of the top guys on the planet. You pass on your knowledge in a brilliant manner that is so down to earth. I have spent most of my life working on my own cars and motorcycles. I wish I could meet you and Cathy I'm person. What cool people you are. Good luck with the new work shop wish I could help you guys move shop. Hemi, Maori for Jim .New Zealand / Tasmania.
This shit used to take years to learn. Guys who knew didn't want to be bothered by stupid kids lol. My inner child thanks you
All they had to do was read the Holley book! 🤣🤣🤣🤣🤣🤣
"remember, the middle hole is the happiest, you've got to play with it" Classic UTG
I would be in heaven if the wife would say that just once.
That’s what she said
This is Classic .😜🤪😂
Is that the "third input?"
Wo0o0o0o
I love it when Uncle Tony talks breaker-points and accelerator pumps. Today, everyone's thinking and reasoning abilities are marinating in so much out-of-touch and abstract digital technology that no one even recognizes any longer which way is actually "up".
4:12 Life lessons. The middle hole is the happiest... You gotta play with it.
Just avoid that butthole....
This is the dude you spend with Saturday night in your garage with a 12 pack and a grill.
Thank you for the knowledge.
Got a holley on my 66 chevy.
Know what to look for
I'm extremely lucky to grow up at a family car dealership and watching old timers (old now) show me tricks from carburetors to auto body and painting. Being 31 yrs old and knowing this old school stuff isn't in those ASE tests. Having that upper hand against a young ASE certified tech is priceless. I love that I can still learn new things from others like you.
Another great video Uncle Tony.
Men like this are few very well explained I appreciate you being clear and direct
Great video, UT! I’ve tried my hand at carb adjustment many times over the years, with spotty success. This gives me a better understanding of the mechanism that I’m sure will help me going forward. Thanks for what you do.
Love these simple tips that make such a huge difference. There are less and less people to share this knowledge. And for young people that have experience with new gen programmable cars..... The combination of any 5 or 6 of these little tips from Uncle Tony. ( sounds weird even to type. I'm at least as old as Tony lol ) , would make a full second or more difference at the end of the run. And huge advantage in roll on, in the street say. It would be the rough equivalent of that first stage one tune on an otherwise completely stock new vehicle. As in... no amount of money you spend after that will ever make as much of a difference.
My cousin was a motorcycle mechanic with a fondness for British and Italian bikes, as well as cars.. And had a 455 Buick that would snap to redline like a 340 dodge smallblock. Was amusing as hell...
I can’t believe UA-cam censored the closed captioning when talking about timing being “retarded” vs advanced. It’s a technical and medical term not a “bad” word.
with all the craziness in the world, it's hard not to believe anything.
it's a silly world we live in..... "we" need to cancel the cancel culture.....there are more of us then the cry babies (a lot more....we are just quiet right now )
@@oldpolak5203 this generation grew up on a book called "if you give a mouse a Cookie" where this little mouse asks this kid for one item and continues to ask for more and more until that child gets fed up.
I'm 27, my parents are immigrants from communist countries my father of which barely escaped alive. I grew up as an outsider watching this culture Fall apart, and hearing the commentary of my dad before things got to the point of him fleeing. it's nothing extraordinary, it's not impossible that the US will go under if allowed to continue its course.
we are in strange times, and although Tony made a video saying they won't take racing... they're trying to take kids parents and swap their genders (yet raise the smoking age) which is 10x more crazy.
car guys are very simple, we like facts, input and output. no other machine can be maintained by an individual, and take them across a continent. Car guys love freedom and individuality, honestly it's the only thing that keeps some guys from lashing out and becoming total dick heads in society.
At the same time do not be discouraged, because Communists have used that as propaganda time and time again do not be discouraged, do not give up. talk with your friends, with similar ideas and sit in on a city hall and just troll the hell out of your retarded local politician they may start to get the idea when a lot of people start coming in commenting or even interrupting them when they should be interrupted.
I can easily beleive it. No-no words used to be an Orwellian joke. Welcome to the new, happier world.
Didn't know UA-cam had closed captions? But not surprised. I understand what is being said here so I would never have looked for it. I don't have time to waste looking for something like that when I am actually trying to learn something. Now I have to figure out why I just wasted time writing this and not reading a post that applies to a carburetor.
Uncle Tony is the man! Damn.. and people think fuel injection is complex. Much love and respect Tony. Im 39, and my first car was a 1974 Chevy impala. Put a cam in, and some long tubes. Converted it from a two barrel to a Edelbrock 750 cfm four barrel. i was in highschool, and it was the late 90s. oooh do i miss that car. that son of a gun was a torque monster. Oh, forgot to mention it was bored 30 over, and had a 400 crank thrown in. Bought it from my good ol mechanic teacher in high school. Bought it from him for $800. Keep up the great content.
I try to remember as I'm reinstalling a Holley float bowl to rotate the bowl by hand clockwise as I tighten the bolts so the bowl is tweaked the same way each time to save readjusting the accelerator pump arm. Its a little thing but every little trick helps
Darn, kids always screwin' around 😁😂🤣 K.I.S.S. don't over think it! I needed that refresher! THNX!
Thanks for the videos Tony. My dad passed about 20 years ago he would have loved you!
I've got 650 Double Pumper on my 350 and I came across across this video trying to find out why my El Camino stumbles on hard acceleration, after the first 3 mins of watching I went to go check the adjustment to find the damn arm isn't even resting on the bolt but instead is above it! your video has FIXED my issue and additionally I now understand my Holley and carburetors in general a little bit more. You explained things well especially for a younger enthusiast such as myself.
This solved my edelbrock and holly carb problems this information is priceless thankyou for teaching my generation how things work
One small thing to add. On a Holley design, When the idle speed adjustment screw is turned in either direction is will change the accel. Pump adjustment as well. So any time the screw is turned double check pump adjustment.
Very good point
Great info as always! I enjoy the carburetor tech tips for street/strip. So many want to convert to EFI. I still like a carb on these cars. I just don’t know all the tricks. Thanks for sharing the carb stuff!

Well, maybe I can get my old Big 10 to finally get up and go!
That's what she keeps telling me. wasn't sure what she ment, thanks, now I know. lol
i love carburator talk , thanks uncle tony :)i used to run a 750 dp and ran 11.13 @ 123 on a hot day so i decided to swap it and run my 1850s 600 vac carb which i use for driving to and from the track ...long story short i did every single adjustment to it that you just mentioned in this video , pump shot , cam adjustment etc etc and i dialed in that little carb and the car ran 11.21 @ 121 on the 1/4 .....so yes indeed everything you said in your video is key to dialing in a carb whether its for street or strip or a blend of both worlds , thanx utg :),,,btw i havent seen you throw carb parts to the side in a while like your first videos , i miss that
Thanks Tony. Good info. Did'nt think of checking clearance after r and r of fuel bowl.
love the hole in the middle!!! but it can get you in a heap of trouble, thanks Uncle Tony!!!
I was seriously just thinking about this issue in my 318 Barracuda.
I have been playing with pump cams trying to get my 340 to launch off of the 2 step. I was the guy neglecting the adjustment bolt on jet change untill now.
What a breath of fresh air , these carb how to vids are great . This video reminded me of the video when you you were adjusting the carb on your dart and you threw a part on the side of the road lol . Cheers
Thank you for taking your time to pass your experience to others much appreciate and much respect
You should try to find one of those old school predator carburetors like the one bigfoot ran on his truck, them things have some of the best throttle response.
Ha! Really?
@@johnsheetz6639 yeah, check out some videos of them, the way they are designed makes them incredibly snappy but they are rare and pretty expensive and are difficult to find parts for but they are worth the trouble.
@@briang4470 i will and i dont doubt
Idk if they had an idle circuit?
You’re the best uncle Tony! Watched three or four accelerator pump videos before I finally got to yours and now I understand it 😀
Thx for the info UT. Its nice to have the little things entombed here so I can come back. If I ever need to.
A good basic primer on carbs , just got done with trips on a Yamaha outboard , complete rebuild and setup , lots of fun .The problem is yu don't mess with that stuff in these days of injection very much. , thank you .
Some people be working on carbs for 40 years n dont know the importance of the accelerator pumps. Or jet sizing this guy knows his stuff.
You should show a video on how you tuned the carburetor on the slant six in detail
I always laugh when Tony says when you ever you start to screw around lol
Keep up the quality info, old school is a dying art. i"m well versed in old tech but still pickup tid bits from you. keep up the good work! From across the pond (Australia)
Man I love the carburetor stuff when I was 19 we had an old Ford f-650 and the carb went bad so I said I would rebuild it and my dad’s friend said he will mess it up well he was wrong I did my research and it ran so good me and my dad were proud
I had a 79 coupe deville when i first watched this video.. i somehow ended up going down the dreaded APT adjustment rabbit hole when youre dealing with a Q-jet. It was aweful lol made my own tool out of metal brake line to reach in there and make adjustments. Found a big empty parkinglot and made some clouds hahahaha
Back in my day Holley sold a trick kit you could get and it had different cams for the pump arm and diff squitter nozzles power valves and other giblet's to tune your engine
Like most of us with a holley and an edelbrock available.....the AFB is on the car and the holley is on the shelf.
Your a very smart guy thanks for passing this valuable rare info on to us all
Carb talk, with Uncle Tony's Shut up and listen Corner..
Oi oi oi
Right as we are having a BBD discussion
I never really considered the slop in the accelerator pump arm changing due to the float bowl screw tolerances.
I put a tad of pressure on it, but still check if I'm not over extending the diaphragm. I should be good 🙄🙄
I have a stumble when I let off on the throttle. Idles good , accelerates good. Edelbrock carb.
Im 74 finly have time for some fun toys thanks for explaining
Just your friendly reminder that a proper APT (at part throttle) setting on your quadrajet and a FAST brand APT adjustment kit so you don't have to take apart the carb to adjust it, really does make a difference.
Tony, you need to check out the Thompson Performance Powerblast Plate. I know it sounds hokey but just watch it in action on UA-cam. It is essentially a little brass plate that installs above the pump squirters. It converts the pump shot from a stream to a fine spray for much better atomization. One look and you'll be a believer.
Squirters can make a big difference when you tailor them to the pump cam .Both need to work in concert to get maximum response .
I agree with checklist first. Plugs and wires need to be good before condemning carb. Had a bad wire that caused a bog on the hit. Thought carb but found wire.
I literally just got my international running and was wondering why it would bog down when I gave it gas...well I hop on UA-cam the very first suggested video😂
Thumbs up Uncle Tony! I always learn something here. Great video.
Thanks Tony
Great informative video !! My holley stumbles at half throttle might try opening rear barrel screws half turn more than front now they're set about same
I thought there was only two holes down there 😂. Great info 👍👍
Killer video brotha! Excellent explanation as always 👊🔥
When I found out about pump cams, My world CHANGED
There are 2 trains of thought on the accelerator pump adjustment. One is what you said here but the other is at wot make sure the pump is not bottomed out. That is where you need the clearance. Which is it?
I like the tech terms- "...the one in the center is... the one in the center">
Right on
Valve lash. Set the valves - if applicable. It can make a difference.
I have a p-80 I don’t know the size it’s on a 1956 Ford fairlane with a 272 y block 3 speed top loader I’m thinking it’s to big stays running in idle but when I pull off its die down or burn tire then die back down
UT.. i’ve got a 40 Ford with a Chevy 350 small block, no modifications with a Edelbrock 1406 four barrel. During the cooler weather I noticed it running fine as the weather got warmer it seems like it actually had to be leaned out because in the warmer weather it wanted to stall out sitting at a light for it hesitated when you went to takeoff and as you let off the throttle after going any type of speed over 50 or 60 it would backfire a lot out of the exhaust pipes but not the carburetor. At one point the idol was up there nice around 900 850 in gear it would be about 650 to 700 which which I liked because if I turned on the air conditioning it would even go lower but lately it’s Gone back to this almost to Rich low idol 400 in gear 600 in Park. Is there a generic starting point I could go with on that 1406 screw both mixture screws all the way down back them out one and a half turns or or watt and then adjust the idle screw from there because it seem like I had it right and then I went for a drive and everything changed to get real high idle it started that pop in again out of the pipes it was surging again while driving it’s slow any help there thanks JT...I just wanted to add the guy that works on my car is a real hot rod guy and it’s hard to get with him sometimes and with the weather change I had to monkey around with the carburetor myself before this kind of stuff he had it all right in that cooler weather and I know the timing and everything is good on it I’ve got a new transmission in it new torque converter new fuel cell so I drive it every day it runs great but that carburetor is becoming a erratic
Man you're just a hell of a guy to put all this information out here. Thank you.
I used a thompson power blast plate on a holley fixed my hesitation
I haven't deciphered exactly why, but on Carters, including Thermoquads, it's important to have the S hook in the correct direction.
Because it's not a equal length
Great video
Right, initial ignition setting is very impotant! But why don't you mention the throttle plate to transition slot relation here? Mostley you can not fix a of idle stumble with the accelerator pump, if this is not set correctly. I really like to watch your videos! Chris.
My Holley pump isn't squirting fuel as soon as I touch the throttle linkage...
Your a legend
Uncle Tony where do you find the time or patience to make so many videos
I have the most stupidest question...Are both jets supposed to work at the same time? For a 2 bbl? Or is one a idle jet and the other a main jet.
what about a intermittent pump shot on a holley 4412 i got good fuel pressure clean carb motor is mechanically sound but when you give her full throttle sometimes it will give a nice full shot & some times not
With modern gas, the diaphragms for the accelerator pumps like to tear more easily too.
It uses seals like master cylinders? Floats are dirty
Great job, very useful information
I've got a practically new holley 600 on a completely stock 350 and it ran great on there for a while but now it idles high when it warms up and has a bog on any kind of even mildly hard acceleration. Acts to me like a vacuum leak but I absolutely can not find one
Blue Road Toad?
my 4160 Cab on my 390 engine, i had to spray gas into the Carb for the car to start it wasn't spraying when you press gas, , i rebuilded the carb now it's spraying but now i have to press the gas to start the car once i stop pressing gas car turns off, any suggestions please?
In my experience with Holley carbs, the accelerator pump discharge nozzle sizing is the ticket to smooth operation without stumble or bog.
Unlce tony. I just came across your video. Im having those symptoms (new car) 1988 ford festiva 1.3 carby.. it has a slightly bugg,struggle when taking off. I have no experience on carburetor. Could ypu guide me on how to check replace the accelerator pump? I can email you some pics
My 225 Lean Burn Holley 1 barrel '82 model 1945 smog carb I don't think has multiple holes but does have a U shaped bendable linkage. Can I bend the linkage for more pump? or do I need to drill more holes?
Unlce tony. I have some carburator questions. Do you think i can send you some pics and where.... i have a 1998 ford festiva 1.3. As far as i know the carburetor is made by aisin.
I have a small buy/hesitation when you barely tap on the gas. So it hesitate everytime you take off. Its only in the beginning. After that its fine and runs good after that.. i changed the accelerator pump thinking it was that but it didn't help much.. the carb has a knob and also a adjusting screw. Do ypu know where to start and how i can send you some pics of how the carburetor looks like
Tony Mopar or no car
Hi what about a flat spot at 4000 rpm? Then wakes back up. Advance sticking?
A bad spot on a old Holley is the ball check valve on the bottom of float bowl. Too much clearance between ball and retainer bar and pump shot will be wasted going back into the float bowl. Modern rubber check valve eliminated this.
Gold.
hey thanks mr.tony.🌚👍.
on a holley 850 front squirters is there supposed to be a checkball under the squirter or just that rod? Since carb was new d.side of the squirter dribbles then squirts. Changing squirters same thing. Im lost...thats my hesitation when I blip the throttle at idle.
My holly six pack accel squirter doesn’t have the 3 holes. I noticed it has cam actuation, do you just replace the cam ramps for different levels of squirt aggression? Thanks
I love your videos! Watch them all the time! I do have a question tho. I have a Holley 4160 750cfm vacuum secondaries. Off idle punch is great but half throttle it bogs and tries to die. Fresh rebuild, new diaphragms and power valve. Everything else checks out great. I was running an Edelbrock 600 and everything ran great and I switched to this Holley and driveability went into toilet. Any suggestions? Idles great, responds great but driving at half throttle it cuts out
My edelbrock shreds accelerator pumps after minutes of use. Wish they were made of something a little more heavy duty.
the pump hole must be smooth, fine grit paper will do the job
I'd try smearing a little dab of vasaline on it after making sure there was no rough spot where the plunger rides.
Theres gotta be somthing pokin out to do that... The pump body should be perfectly smooth. Either that or maybe youre damaging them when putting them in(??) Im not being insulting, speaking from experience. In my early wrenching days i didnt understand "finesse" LOL and tore a few...
Most people look thebiggest problem of all
A loose connection between the steering wheel and the driver seat
Great tips from UTG, but he's yet to mention how instrumental a Wideband 02 gauge is in tuning a carburetor for EFI like performance.
ill see you tomorrow ;)
I am.. not.. playing with my holes Tony.
Man, I have a very important question for you and I can’t seem to find a way, please let me know how to ask you a question
A completely unrelated question would be how fast can cars be before you need to buy a trap door oil pan? I'm running a front sump pan.Sounds like some engines blow up when trying to stop too fast as well with a rear sump configuration.
CULT LEADER UTG!!!
Thanks Uncle Tony,I learn something new everyday.Do you remember when Demon Carbs came out? I bought one and it looks very close to a Holley except it's prettier.It's a 625cfm. I want to put it on my 350/300 crate motor thinking it would be a nice to drive smooth running carb,not to big and not to small.I saw an article on the motor I just described and bought it but they showed this engine with a Holley 750.My question is ,Is the 750 to big or the Demon to small? The car would be a week ender with a little show and go.I figured the 625 wold be a good all around carb.I did go to places like Summit and Jegs looking for parts for this carb BUT all they have now is a newer style.If the Demon I have turns out to be too small I figured I could get the parts I want to bump it up a little more than it is.I haven't started the engine yet I just took it out of the crate and put it in my car so that's why the question.I figured you have tons of knowledge and couldn't go wrong asking you.Thanks Uncle Tony...
