same here, now i know i questioned if my secondary's were even working

[@karlbishop7481]

I didn't know this either. I always wondered why my Duster had that occasional stumble. I no longer have the car which I kind of regreted the Edelbrock instead of the Holley. I knew how to tune a Holley but not the Edelbrock. I had a well warmed 360 in it, ran well but I knew there was more in it but didn't know how to get it. Thanks Tony, I learn something from every one of your videos.

[@loganpe427]

Wow, all you folks here with the mystery AVS issues. I understand and was always happy to educate my customers like you all. They were happy too, to finally know they didn't have (or buy) a junk carburetor. The word of mouth business I got back from people like you was fantastic, thank you! Tony's the greatest right?

[@Fenderman1235]

[@hotrodray6802]

Very few people understand Holleys too. It's rare to meet one who really understands them. A little knowledge is a dangerous thing.

[@hyperluminalreality1]

Until they don't. Aluminum carbs do not age well and actually change their tune as they corrode inside. In a dry environment they are fine. In an wet or humid environment, these seem to corrode and give major headaches after a short run time. Tony has not had to change out several of these that were no longer responding to tune it seems. For him to say that the reputation these have is because nobody can tune them is nonsense. And if they are that much harder to tune than a Holley....Anyway. Give me a 1965 AFB any day. A non corroded one that is. I had corroded AFB troubles back in the 1990's on a 1965 Buick Sportwagon with a 300. To deny this massive manufacturing failure is just fanboy shit. These carbs do not last like ANY zinc carb.

Thanks Tony, I haven't been able to work since 2009. I'd stopped thinking about this stuff and thought I'd actually forgotten things. For 20 years before that people thought I was magic on tuning & carbs, even other mechanics, just because I knew the tips you talked about! Carter's are the bomb for a street car and people hated them cause nobody understood how to tune them, so I got tons of happy customers and had a blast. Thanks for reminding me! 👍😁

I love the Edelbrock carb. My shelf in the shop has a few sitting on it that I got for free or peanuts... because the guy I got it from said "it's a POS..and I'll never get one again...their loss has been my gain...user friendly for a young hot rodder because if you pick the right size it will give you good results right out the box.

[@hotrodray6802]

Yes sir.👍 $100 will still get you a new take off POS. LOL Been my favorite since 1960. 👍👍

[@hotrodray6802]

The reason is that Holley power valves are either on or off. Edelbrock rods move proportionately by the springs. Original AVS (RoadRunners etc) had 3 step rods.

Wish I could find some old Quadra-Jet carbs like that since people talk so much shit about them.

[@JasonOBrienThinksHeCan]

As a teenager, my dad and I ran a Holley on a 67 mustang for a couple of years; it felt like it was always a science experiment to keep running nicely. Moved to Edelbrock and it was an absolute breeze; literally ran the thing for 20 years without opening the carb up (not recommended). Two years ago, I replaced with another edelbrock and it was a breeze to get tunes again. For street and convenience, I would choose these over Holley all day long.

[@JamesAutoDude]

I'm going through this now with my Holley. Nothing but a nightmare and too much of a hassle to deal with the powervalves and everything inside the freaking float bowl 😒 plus it's developing so many common Holley leaks Switching to Edelbrock!! I just don't want the hassle anymore lol

[@garymcmullin2292]

so glad to finally find a wrench turner that recognizes the real qualities of the Edelbrock. So many other channels just talk shit about the Holley. I had run Holley since the mid 1960's and I can tell you they are a pain in the ass....always going out of tune with vacuum leaks in the nasty valve body gasket and their choke system never was worth a crap, it too would easily cause too much load up. I finally relented in 1997 and put a 650 Edelbrock on a well built ford 400 in a pickup. I never knew life could be so good since that time. The electric choke has been flawless even to this day on that old "78 4x4. The carb never coughs, never fails. I have never experienced the stumble from dry circuits you describe....ever, just start and run, never fail. It is super easy and convenient to pull the top and check/clean float bowl and make metering adjustments if desired. This design is so superior to Holley for street use it is ridiculous. I have a couple of Demons run on a stroker...the ones before Holley got hold of them..... and they have worked extremely well too but none can match the smoothness and easy start of the Edelbrock.

[@charleshubert6751]

That secondary circuit was news to me. Thank you for that. I watched you lift that step up spring with the metering rod, that was beautiful! Once again a terrific video and I've always liked these carburetors, the first AFB my father put on our 1968 Chrysler 300 in place of the original Holley back in 1971 was a real eye opener. Keep making your great videos!

[@JesseWright68]

Absolutely. The side gaskets on Holley bowls are a pain in the ass to keep ftom leaking, especially on rigs that sit for long periods of time. Getting away from Holley was one of the best things I ever did.

[@peacfulseas]

The AFB's were overlooked because they looked to simple to work so everyone went for the " had to better " more complicated Holley band wagon. I've run AFBs on street in dual quad configuration since the mid 60s, easy to flog on the go. Have a nice pair of Holley 650's for MY 360 tribute build of Dad's '74 D100 shorty stepside. FYI Carter manufactured AFBs for marine use. The primaries and secondaries are the same size,4 big holes. I found mine in used marine salvage yards.

[@177SCmaro]

Funny thing about that is I'm pretty sure afb/edlebrock's actually have more moving parts then a Holley which is probably the main reason the Holley design won out in drag racing. Either carb is simple to mess with. Hell, they make externally adjustable jets for Holley if you can't be bothered to drain the bowls and remove 4-8 screws to change jets.

[@peacfulseas]

@@177SCmaro Yup if your schooled in all that but most aren't. Chill dude Never said one was better than the other.

[@177SCmaro]

@@peacfulseas Neither did I. I pointed out its funny to me if the perception of Holley was "more parts, more better" since they're actually simpler carburetors.

[@peacfulseas]

@@177SCmaro I have experience with both,run both. While the AFBs might have more moving parts(?) tuning a Holley for the novice is far more complicated. Power valves,secondary vacuum springs. None of which the AFBs have and are more forgiving when making changes that don't require a complete teardown. UT,UC channel is aimed mostly aimed at beginners but I'm never too old to learn from anyone with experience.

[@177SCmaro]

@@peacfulseas You can get both carburetors with or without secondary air valves/springs and the power valve is mechanically simpler then metering rods (although more of a pain to get to but can be deleted for racing). My main beef with, at least Edelbrock's, is their crappy/inconsistent accelerator pump design which fucked me out of many a race with the infamous random "Edelbrock stumble" at the line. Other than that I found them to be fine carburetors. Great for the street. Ran one on my pickup for years. But when I go racing it's a Holley double pumper-style or nothing.

many people hate these because they can't tune em. they think turning the idle mixture screws is "tuning"... I personally love them because they give you no trouble once you have the right jets and metering rods in them for your application. and they're not elevation sensitive... not as much anyway.

[@bobstephens8851]

You are 100% right about guys trash talking Edelbrock carbs because they know nothing about them. Most of them have tried one and didn't know you can't run more than 5.5 lbs of fuel pressure or it leaks gas all over the engine. I have a Carter muscle car series fuel pump designed to work with an Edelbrock carb that has a max pressure of 5.5 lbs and only drops to 5 lbs at full throttle!

I prefer these carbs for street use on a square port intake. On a spread bore, a good pre computer controlled Q-get, or a Thermoquad that has not been cracked. I find that these carbs are also prone to boiling the fuel in the carb and are sensitive to fuel pressure. A heat shield under the carb works wonders, and keep your fuel pressure to 4-5 psi and they are a set them and forget them carb that will work flawlessly for years.

Carters are cheap and he even said so. And are for people with little understanding of carbs. Holleys are for people that know how to tune an engine . They are better built. Another thing a holley just looks way better.

[@eugeniobrianti8755]

I have Holley and Edelbrock and have had good luck with both thanks for the info.

[@wileecohagen]

The difference between the AFB and the AVzs is that the vacuum secondaries on the AFB are counterweighted, and the AVS are sprung. That means the AVS is adjustable, the AFB isn’t, unless you want to remove weigh from the counterweights. I’ve never seen that done, but in theory it should work. But I wouldn’t try it unless I had a second air valve to replace the one I tried to modify, in case I s rowed things up. I’m not even sure where to remove weight. The best way to do that would be to drill it out. Or, if the carb is too big for the engine you might try adding weight to the counterweights. Ut the. You have to find a metal that is heavier than the metal the counterweights are made out of, drill out the counterweights and somehow replace that mass with heavier metal. You’d be better off finding an AVS. I think the HolleyDemon carb is their take on an AVS. Ok, I was partially wrong. Edelbrock was selling AFB’s but now sell what they call the AVS2. Holley sells an updated version of the AVS. Tossed with a Thermoquad. Both carbs would be worth looking into for a street or stret strip engine. Of course if you found an original carb of either type, whet I sad holds true. Have fun!

[@MrMopar413]

Great video I never new that about watching those plungers while the engine is running. Another thing about afb’s is you don’t have to worry about backfire destroying the powervalve.

Very knowledgeable. I have been using them since the 70s and I tell the people who don't understand them the same thing. Thanks for putting the knowledge out there for the young racers.

I love my Summit 600CFM carb for my 73 Mustang 302, and feel like I have it pretty well rounded out now. But for that thing, I had to buy every tuning jet, discharge restriction and secondary spring on Summit to optimize it from factory calibration, with an oxygen sensor no less. My used, $40 Edelbrock I stuck on my $400 84 F150 302? Never a flat spot or economy issue every day of the year after a couple minor adjustments. I may love the cheapo Edelbrock more.

I HAVE 2 650 AVS THUNDER SERIES ON A 496 MOTOR IN MY V-DRIVE BOAT EVERYONE SAID THEY WOULDNT WORK BUT ONCE I LEARNED HOW TO TUNE THEM THEY ARE SO RELIABLE I LOVE THEM.

I had a hard time finding the EXACT accelerator pump for my Carter AFB. After 3 different rebuild kits and the standard Edelbrock parts, I could not find the correct pump and therefor get my Carter AFB to work properly. That's why I went to Holley. So many people are afraid of Holley and how complicated they are. For me, I find them actually easier to adjust and tune.
