i pulled a edlebrock carb off my engine replaced it with a holley and it came alive both where new carbs quadro jet is a way better carb plus u can drill it out easy to work on just u must reseat the fuel bowl on the lead plugs or if it leaks at all it will affect the secondaries. the edlebrock i feel is the worse carb and the cheapest carb on the market junk not worth the money . u do know u will get better performance out of a quadro jet then a edlebrock carb and u can drill it out to 1150 cmf's . i have a bunch of edlebrock carbs most i got from rigs that they put one on and when i get it, it comes off and goes in a pile

@@MuscleCarSolutions lol can get the left over parts???

[@pulloutking6468]

My solution I used for your “ugly” was getting the Edelbrock part# 8128. Remove the feed plug on the driver side of the Edelbrock carb and install the part# 8128 dual feed fuel line. It keeps both bowls equally full at all times. So it doesn’t matter if you make hard turns or go off roading like me, after I installed this dual fuel feed line those problems went away.

[@Texasmule]

I did the same thing, my drive way has a hill that I have to drive around and it leans my truck to the left Which bogged it down. I tried a DP holley and it worked but I sat there for hours trying to get the dam thing to idle correctly and it was really rough when I finally found a sweet spot. My cam was already super choppy and it made it sound really disturbing so I took it off and just hooked another line to the avs2 and fixed everything, had to increase jetting but I haven't had a problem since then

[@slowcountryboy476]

I just asked why a "Y" could be centered to feed both sides and read your comment. Maybe even set the floats so both bowls hold more fuel. So I am not the only one with your thoughts; there is another similar comment about the same technique that cured the problem. Hey, and I bet we are all just carpenters who happen to see details and figure it out right. My solution for fuel sloshing around while "rock bouncing" is to extend the breather inlets. On a Motorcraft 2150 a peace of tubing can be rolled like a tubing from a still above the carb, but below the air cleaner lid with holes drilled on the top coil for breathing. That keeps fuel from sloshing into the venturis and flooding the engine. My concern against EFI is the Goodyear ballon "accidentally" detonating high above the dirt and taking out an EFI and other electronic stuff. It will not take out mechanical stuff, such as a carb. Look at how that choo-choo "accidentally" derailed and I bet more "accidental chemical derailments will occur. Too many accidentals to think something ain't up. Be safe and keep your powder dry.

[@tonymayhew191]

I got fed up with trying to learn about carburation on my own when I was in my early twenties, so I bought a book from a guy named Doug Roe. This guy was employed at the Rochester Quadrajet factory for General Motors and then I started learning about Quadrajet carburators! I highly recommend this book of his knowledge this man filled the book from front to back where a second grader could start rebuilding carburators! But the guy on a webber carburator video I watched last year said it best! That screw on the side for the throttle plates has no tuning purpose whatsoever! That it needs to be adjusted to where the throttle plates don't come back and contact the bore wall if it were to be snapped back and then released! If you go gettin crazy and and try using the adjustment to raise your idle you will get into the off idle circuit and it will fall on it's face when you punch the throttle from a dead stop! 😉

[@Gary-Anglebrandt]

He's right! That book is great. It's on my shelf! I ended up going with Edelbrock but that book beckons to me sometimes -- "get back to messin' with the Rochester, it's worth it..."

[@tsmith578]

I hear you talk about heatsoak on carburetors , particularly Edelbrock . one helpful thing that I found is besides using a phenolic spacer , is to also use a spacer on the air cleaner , that is hood space alows for it . I installed a Edelbrock phenolic spacer which is actually only about a 1/4 " thick , and I also installed a 1" tall spacer between my air cleaner and carburetor in my truck , and it really helped it out a lot with heatsoak , because the extra space lets the heat disapate from the carburetor instead of the air cleaner just holding the engine heat down over top of the carburetor . and it also has a smoother idle on hot days . Tim from Wisconsin.

[@chuckroast5735]

I can not overstate how important proper fuel pressure is for proper tuning of your Edelbrock carburetor. My suggestion check your pressure, add a regulator if necessary before you even start tuning. 5.5 psig seem to be optimal for my AVS.

[@davidparslow1321]

Great video, so helpful, I managed to improve the fuel starvation issue when cornering by having 2 fuel pipes, one supplying each float chamber.

[@MuscleCarSolutions]

Glad you found a solution to work for you! Good work!

[@jeffjohnon4223]

Using the Edelbrock fuel pump helps too,6 psi and 140gph, that is a HVLP pump. Float setting is crucial on those but once you have them dialed in, they really work good.

[@MuscleCarSolutions]

The only issue I have is not the set pressure, but not having the opportunity to adjust if needed. Plenty of times where a little less pressure is called for. So I’ll always be a champion of adding a good regulator and a gauge to have another point of adjustment in a system that doesn’t have that many. For sure a good quality pump like Edelbrock is a great starting point.

[@bobeaseshop9389]

I run two Edelbrocks one on a Pontiac 389 (1964 Bonneville) & one on a GM 305 (a 1978 motor in a 1957 GMC) and both are great. I do not ever push anything hard so in my world these are near perfect. It did take time to get the needles, springs and jets within my needs. Early days it was run it and look at the plugs but now I use an air/fuel gauge. Not hard to fit and worth the time and makes tuning so very much easier. I have some videos on this but overall there are more detailed ones. I have worked with Holley carbs but don't like them as much as Edelbrocks. I run a Weber on a 1970 Triumph Spitfire and loved learning about them (a sync not progressive) and there the air/fuel gauge was a must. Just wanted to toss that in. If anyone out there wants to add an air/fuel gauge be sure to shop around and get the best quality you can. My first one didn't last but a few days.... just shop and you'll see. Hope that helps.

I put aclerator pump part number 1468 for a 800 in my 650 avs. It help a lot

[@Clydes.Shop78]

Great info as usual. I think a lot the Edelbrock angst is like the Ford vs Chevy vs Dodge drama...a whole lot ill informed opinions based on one off experiences.

[@MuscleCarSolutions]

True. Though the carb thing is generally based on not applying the right solution to the equation. When you apply the wrong part, the outcome is bad. But instead of blaming themselves for making a poor decision, it’s easier to just blame the part then taking responsibility.

[@mattbauckman9907]

I actually think Holley’s are more complex. Edelbrocks are my go to. Excellent carbs.

[@MuscleCarSolutions]

They can be. The last 20 years have seen Holley make some tunability upgrades which have given more way to find the right settings for an individual application. But the Edelbrock carbs can be extremely user friendly if one takes a little time to learn them.

[@vaghol]

I have an AVS2 and I am happy with it. I run a wideband and it's easy to get really good numbers. Very tunable. I do have an off idle stumble/hesitation. Top hole on accelerator. I drilled the squirter out to .045 and it helped. I ordered a Thompson performance carburetor power plate and hopefully that's enough. You can also get the 1468 heavy spring accelerator pump, like someone else mentioned. I do think that's the only real flaw of the carb. Like you said though, more to do with ethanol than a bad design. Still a great carb and I would recommend it for an street car. Great video.

[@MuscleCarSolutions]

I’m not a fan of that plate, especially on an annual discharge carb that atomizes the fuel/air mixture enough to start the process. The ethanol is a challenge on a couple levels. Such a pain to work around and one factor that almost no one considers when tuning. I’ve been working on an internal mod to the carburetors to open up the fuel passage. It’s a choke point in the system when putting the big pump in and a larger squirted nozzle. So far the results have been minimal, but I’ve just started on it. We’ll see where it leads. 99% of the time these carbs can be tuned out of whatever issue it’s having with fuel delivery. So it’s a bit of a pointless exercise, but something I’ve wanted to try for a long time. We’ll see what happens.

[@sjd7188]

I had a stumble with my eddy 1409 on-my boat. The accelerator pump linkage had some play had to bend the rod to lengthen it to keep pump under tension at all times. I was also running a AFR meter, what i saw was after nailing the gas it went way lean for a long time. Before the AFR meter i was thinking it was lean so i kept richening step up rods and jets creating another stumble later in rpm range…. Had not had the afr meter i would not have seen how lean it was going just after hitting throttle, and how long it took engine to recover and then go way rich… taking the slack out of accelerator pump linkage made it disappear, then going to leaner rod helped the holeshot situation .

[@vaghol]

@Poor Touring Hot Wire Garage It's not really an assumption. I can watch my AF go lean for a moment when I accelerate. Also, if I pull the choke out slightly, the problem is gone and It it's very responsive. I did also mess with the timing until it started skipping. Thanks anyway though.

About the ugly, my Edelbrock AVS used to stutter and stumble on hard lefts just like you said. That was with a rubber fuel line. The problem stopped after I installed the hard fuel line 8126 on the passenger side. It may be coincidence, and I don't why that would have fixed the problem, but it went away after that change.

[@NilesJStJohn]

Great informative vid and lots of excellent pointing outs of positive n negatives . I do want to know. I have a mild street Mopar 318 with Weiand stealth intake. I have a AVS 2 on American untying n it . Had a 69 440 magnum factory AVS on it n ran very well but wanting better fuel atomization as well as maybe some power gain. It does have 8.5-1 compression. High swirl 302 casting heads and a Hughes cam designed for my combo. Hyd flat tappet with .486 int and .502 exh. I run 3/8 fuel lines tank to Carter hv mechanical pump and a pertronix flame thrower 3 distributor and matching coil. Power master high amp alt. It looks a a total street car with 4.10 gears and 2800 stall. Hope w much fuel pressure should I regular it t to will be a gauge right before carb and right after regulator. I run a filter close to the tank and another right after the fuel tank pump. Seems about 6psi should be right . I know I can contact Edelbrock. But would like your opinion. Thank you very much .

[@MuscleCarSolutions]

Lots to share with you to answer your questions and to change a little how you look at it. First off, curious about your cam selection. Check out this short video to see what duration is the number that’s needed and lift not so important. kzbin.info/www/bejne/mH_FqIKDqtyCbLs. Without knowing those specs but looking at what else you have and the low compression you’re running in that engine, is still advise to start at 6psi and tune down from there. Edelbrock’s love operating in the 4.5-6psi range. Any higher you’ll run into too much and any lower (depending on how you set the floats) can run into starvation issues. The flow rate at that psi is good. As far as better atomization is concerned, that’s going to be covered perfectly by the AVS2. Power gain is going to be limited by the rest of your set up. Tuning abs timing are your keys to finding the max power in that engine. I have lots of videos on all these topics if you get a chance to check them out. Watch that lift vs duration video first and let me now what you thing. 👍

[@kevinrandall8327]

I but a comp cams thumper kit into my brothers 65 T bird 390 FE, I fitted an Edelbrock 600 CFM electric choke carby, the car had a flat spot when the secondaries engaged. I fitted a set of main jet needles from a non elcetric choke carby, then adjusted the secondary choke plate to come in a bit earlier. Problem solved without dismantling or removing from the motor, including the road test I reckon the whole operation took about 45 minute’s. And to think that I spent hours trying to get the original ford carby to work properly and a new original ford carby was twice the price of the 2nd hand Edelbrock I bought off eBay, now the car sounds good, goes really good and run’s perfectly.

[@RoofysGarage]

Anyone who laments and degrades the Quadrajet carb is merely just showing their ignorance. Theres a reason that the Q-jet was in production for 25 years, albeit with some design changes. Unlike the Edelbrock and Holley carbs, they were designed for, and primarily used on mass production street vehicles. There were literally millions of them built over the quarter century they were in production. And most of the ones people see nowadays have many thousands of miles and years of wear and tear on them, so for someone to rag on them because of leaky well plugs, worn throttle shafts, or clogged idle passageways, is asinine. While they won't best a race prepped 4150 or demon carb, they are very adaptable, and with a 76+ carb they have excellent adjustability and 800+cfm right out of the box. Yes, it takes more knowledge to tune and tweak a Q-jet than a Holley or Edelbrock, but thats part of the fun! 🙂 Oh and for what its worth, the ONLY carb that i have ever just "dropped on and went" was a late 70s 305 powered Buick with a 600cfm Edelbrock w/electric choke. All i did was tweak the idle speed screw and it was trouble free.

[@hotchihuahua1546]

The majority of the driving on hot rod street cars is in the lower torque curve of the motor . The design of the Edelbrock AVS2 addresses this for the street with a fogging effect . This increasing the burn efficiency of the fuel in the combustion chamber and makes for a very drivable engine , even with a more aggressive cam . More torque and increase mileage is the big reward !

Great video mate. I run an edelbrock AVS 500 on my mild 318,just a mild cam with edelbrock performer intake,full exhaust and hei ignition. The heads and bottom end are still stock. It’s a 1980 Chrysler. I had mine professionally tuned and in the 4 years it’s been on my car it still runs perfect! It’s not an everyday car either,just a toy. I’ve been told by some that the 500 is to small for my combo but I think it runs great,never given me a drama and on the Dyno it made 214 hp at the tyres in which I believe is good for an otherwise stock 318. I changed my diff ratio from 2:92 to 3:45 and that made a big difference as well. I will always run edelbrock from now on.

[@jamesford2942]

On the ugly part I think that the reason you can starve for fuel in a left hand turn is that centrifugal force keeps the fuel from transferring to the driver side. The small capacity of the float bowl is not enough to keep up with demand. That is also the accelerator pump side so that diminishes the capacity as well.

The biggest reason why edelbrocks get a bad reputation is because they are one of the cheapest and most readily available replacement carbs so when uninformed people have issues with their engine the first thing they do is blame the carb when usually they have some other issue like a bad cam or incorrect timing, so then they go to the auto parts store and buy the cheapest carb on the shelf which is usually an eldelbrock or one of those 4160 500cfm holleys and they slap them on and when it still doesn't run right they just blame the carb and call them complete junk. In my experience the edelbrocks are the best set it and forget it, get the job done type carb they are decent and you can find second hand carbs for dirt cheap because most people want a holley, take a $25 swap meet edelbrock, throw a rebuild kit in it and have a decent carb for under $100

Hello Muscle Car Solutions, thanks for the great video. I am on the fence right now with my stock 1990 Chevy 2500, I am having TBI issues I thought about swapping it for a Sniper or Etech, there have been more than a couple of guys complaining about the sniper , so I am considering going to a carburetor, I have always liked Quadrajets for stock engines, I have rebuild several back in the 80s and 90s, I never tuned one like you talked about I just figured they were set up for the engine they were put on. If me and my buddies modified our engines Holly was our go to choice. Now Holly has a Quadrajet replacement that has a spread bore base and larger secondary throttle plate. If I convert to carburetor I have to change the intake manifold and the distributor, I am fine with that. You gave me something to think about as far as the Edelbrock option. I need this 90 2500 to travel from the L.A. area to the most northern part of Washington a few times in the next few months for are retirement relocation. Any advice/recommendations would be appreciated . Spindrift

[@MuscleCarSolutions]

@@spindriff it’s pretty common to have issues with the TBI EFI from that era. It’s like having a flip phone from 1998. The technology is way more advanced and there is no more support left. So switching to a modern EFI will always be the best choice for a cruiser. As far as folks having issues, I can tell you that 95% of the time, it’s user caused. Bad grounds is by far the number one issue. It will fry an ECU QUICKLY. Even the self learning units can be a bit complicated if you’re not used to how to tune. So any issues, people tend to blame the part because they don’t understand how it works. I’ll eventually do a self learning EFI series of videos if I can ever find the time. In the meantime, if you’re more of a novice, using a universal carb like the Edelbrock’s or the Holley is generally not a bad way to go. You’ll need to do some tuning to help match it up with your application, but you’ll have no issue with that commute once you get the carb sorted out AND if you have the right support (fuel system, ignition/timing) to help the carburetor perform the way it should.

[@MuscleCarSolutions]

I’ve responded to this same comment you’ve left a number of times. The .43 nozzle does not come in any of the factory carbs. Right now, that’s all Edelbrock is concentrating on is getting out finished carbs out the door. If it’s not something that supports that, the chances of getting one anytime soon is not good. I probably have one that I would be willing to sell you. I’ll have to look and see. I recently sold a couple assortments of that part number to folks needing them so I’ll have to see if I have any more left.

[@jasont.1530]

You should add a disclaimer, that if you know how to tune a carb, you can tune out the cornering issue. Also the secondary circuit will dry quickly with todays gas and you will get a bog if you floor it right after it sits for awhile.

[@MuscleCarSolutions]

The cornering issue is a design problem that unshrouds the jet on that side. There’s no tuning that can recover from lack of fuel. It’s a fairly well known problem with these carbs, but in their defense they were not designed to be a star on the autocross track.

[@terrencehall7264]

Gday sir. Are you saying that you can't put a second fuel line on the other side of the carburetor with a t or y fitting? At least that's what I'm about to do with mine, but for a different reason, and that reason is BOOST. Just to make sure I don't lean out under boost. It's a drawthrough application. Also I'm going to make a second plunger so I can utilize the empty bowl with some tomfoolery, that holds extra fuel opposite the plunger. 😂 wish me luck😢

[@MuscleCarSolutions]

Edelbrock makes a dual inlet fuel line. You can run them separately with no problem. Good luck with the modifications.

Thank you for making this video. I have a 1974 Dodge Charger with a 318. When I was a youngster I just bought what was cheapest or was available. I ended up buying a Edelbrock carb because it was in my price range. Now knowing more about the carb it is still the perfect fit for me.

Not enough info to offer a suggestion. If you go look at the cam recommendation form on the comp cams website, you’ll see the list of things that need to be answered so a good recommendation can be made.

[@kennethackerman8433]

Looks like the distributor is on the wrong (timed) port. That's only if you're trying to duplicate the emissions BS that came along in the 70's. For the engine to run the best it can from the standpoint of making the most use of energy from the fuel it should be on the drivers side (lower) port, otherwise the fuel isn't being completely burned at idle, some of it is being sent into the exhaust unburnt, which in the 70's they wanted to happen and used air injectors to have it be burned in the exhaust to raise the temp to reduce emissions....funny....wanted to reduce emissions by making it less efficient, lol

[@MuscleCarSolutions]

Depends on a couple things, but timed as an option for street cars is absolutely viable. Not all engines operate best on full manifold vacuum. That’s why there’s options. If it were just an emissions thing, every aftermarket carburetor manufacturer would have ditched it decades ago.

[@Fordcertian]

Disconnect the choke and hold it wide open and see what happens. Make sure the linkage is operating correctly on both sides of the carb.

[@denniskwasnycia1950]

Great video! What is the maximum fuel pressure for the AVS2? I hear they don't like to have too much fuel pressure. The carb I have is a 650 CFM AVS2 that I am putting on a 460 soon. Thanks

[@MuscleCarSolutions]

4.5 to 6 psi is the range you can operate.

[@chuckroast5735]

I run mine at 5.5 psig. You are correct they run rich a higher pressure. I also noticed with a mechanical fuel pump pressure seems to bop around a bit. A regulator will not only lower the pressure but will also smothen out the flow making it more consistent.

[@johnnymeyer4814]

Question/ on my stock 340 chrysler i have a edelbrock avs1 650 carb i installed a delphi “stock” fuel pump after seeing your carb videos i checked my preassure it shows 6 psi idle but when i bring it up to 2000 rpm it says 9 psi? Pump specs are system pressure 6 psi max operating is 8 psi! Should i install a regulator??

[@MuscleCarSolutions]

Absolutely. It’s extremely typical with mechanical fuel pumps. Everyone disregards them as being acceptable to hen in fact they rarely are. Give yourself that adjustability. It’s why I always 100% of the time recommend a regulator. Your carburetor will thank you!

Boomers tend to not care about fuel economy for some reason.. it never enters into the equation in carb talk circles. They forget that carbs are now in direct competition with EFI upgrades. And people upgrade to EFI because of fuel economy and their "self-learning" feature. By the way, the "annular" primaries for supposed better atomization is why I'm looking into the AVS2.. increasing horsepower isn't on the list.. I'm not going to the Indy 500. I'm going to the grocery store and driving around town.. where gasoline is expensive.

[@MuscleCarSolutions]

The rule of thumb is 2% lean for every 1500 feet of elevation gained. It’s pretty accurate and an AFR for high elevations is always a good idea. Helps keep an eye on it and will help in the tuning process for sure. But without one, stick to that rule and you should be fine. If you look at the Edelbrock tuning chart it will give you percentages on the lean and rich side so you can judge where you want to start based on your elevation.

@@scottcolvin4138 If you go to my website you can download the Edelbrock carb tuning guide. Find the tuning charts for the 1406. Look in the cruise mode and start tuning there.

This side of the pond, most seem to use Holly carbs, mostly because of availability. Over here the most popular applications are for the Buick derived Rover built 3.5 or 3.9 Ltr v8. They rarely make a genuine 250 hp in tuned form. The Elderbrock is night and day better than a Holly for that application. As for the fuel surge in corners, start with a higher fuel level and twin feeds. Just something we learnt at the track

[@C_71]

I have a 1978 D150 with a 360 LA stock. I put a Weiand aluminum intake and an AVS2 675 carburetor on it. I live in the upper Midwest and since the roads are clear, I decided to take a drive. Today I've had to do a bunch of adjustments because it died and started stumbling. I noticed it was leaking fuel and getting heat soaked with a ton of vapor after driving it kinda hard. I looked at my fuel pressure guage and it's reading 8psi, now it won't start until the fuel and vapor is gone so I'll have to add a FPR other than a Mr. Gasket.

[@rangelandrevival7763]

I have always loved the Quadra jet carburetor for its mile per gallon advantage, but on my mild vortec 350 it is just not putting out the horsepower that my Edelbrock AVS 2 was before I took it off. And I just don’t have the time to get the Quadra jet perfectly set up, and it is also suffering from fuel starvation, which is an issue on those . Going to go back to the AVS 2 and try to tune out a rich condition at idle. My main question is, do you believe the AVS 2 650 cfm is capable of as good mpg numbers as the Quadra jet when tuned properly? I drive a lot of miles with my street truck so every mpg counts. Great video!

[@regpeeler5509]

Hey there sir, One thanks for the video. This is helping me decide what carburetor I would like to change to. I think I am leaning towards the AVS2 1906. I have been looking at many videos on changing and I am not seeing anything about the choke in my scenario. I have a rockchester quadrajet 4 barrel carburetor ( autoline part number c960) and it has a vacuum choke. Pardon my ignorance but my question is, can I use electric choke as a replacement? Just not seeing any video talking about changing from vacuum choke to either electric or manual. Most definitely do not want to go to manual choke. So wanna go to the edelbrock 1906 electric. What are your thoughts?

[@MuscleCarSolutions]

Yes. I’m assuming you have the divorced choke (choke mechanism is in the intake manifold and not on the carburetor). You can switch to the electric choke easily. I also did a video on how to wire an electric choke that you also might find useful. Let me know if you have any questions!

[@GaryH-pw9cm]

@@MuscleCarSolutions The smog test guy just said it would not pass. I went through the manual and bought a kit to recalibrate the out of the box calibrations to leaner. The second time I did the smog test it failed again except this time the smog guy said that the reason it did not pass both times was at idle not the 2500 RPM test. I wished I would have known that before I messed with the calibration. After blowing out all the idle circuits with carb cleaner and compressed air, setting the idle exactly per instructions, still would not pass the idle test. Too rich. So now I use the 600 CFM Holley for the test and run the 750 Edelbrock on the street. I am running a stock camshaft, and a 351 W Edelbrock dual plane performer manifold. 5 psi regulated fuel pressure. No vacuum leaks. I bought this 750 CFM Edelbrock carburetor new. It runs just fine, so I don't want to get rid of it. .
