Hey man. The reason that car reader is running too rich is because you're turning this flap. Screw the wrong way, tightening the Spring makes it run richer, especially when you stomp on the gas. If you want it to lean out you have to loosen the screw to allow more air in the car braider. Basically, it's like you're running it with your hand over the top of it. It's pulling more vacuum than air, which means it's pulling too much fuel. You're just doing the process backwards. It's no big deal a lot of people can't wrap their head around it, but I'm telling you straight up. You're doing it wrong, take my advice and don't feel some sort of way about it. It's not anything but helpful advice. Or you can sit there and fludge your engine out and wash your soldiers down. All you want, but until you do it the correct way. You're not gonna have any luck with it? So, you should take the video off the air until you get it. Correct, you're gonna have a lot of people screwing their cars up because you're giving them the wrong advice.

I've been a diesel guy my whole life. I've been wanting to learn about carbs by building a small block making 550hp. This is honestly some of the best and easiest to understand information I've found about AVS2. Thanks a ton for making an easy to understand and informative video.

Great video my 99 S10 ext cab 5sp has almost the same setup 350 30 over comp cam vortec heads pro comp aluminum intake shorty headers and the 650cc AVS 2 Series 4 barrel carb with manual choke and it's wanting 2 spit a bit when cracking on her around 3rd 2 4th and 5th gear shifts spits a bit instead of 4 barrel opening up all the way. Other than that she's a nice daily driven hot rod truck that still functions as a truck also.

Awesome info brother! I just put an AVS on my elco and have been trying to nail the idle mixture. I can approach it with some new found knowledge

[aaronpiazzola]

Thank you my friend I really appreciate your video. I just picked up the same carb for my 351 Windsor. The engine and truck is how it was when I purchased it. It has the largest cam possible for the stock heads. I suppose I'm going to run into the same issues you did

HUGE carburetor question. I have the AVS2 on a 79’ mustang 302. When my engine gets a little overheated, the car somewhat stalls / chokes in first and second gear (doesn’t happen when it’s cold). Once I let of the fuel a bit, and ease the pedal, the engine smooth back out and I’m good. It normally happens at a stop. I will be making some adjustments that was stated in your video. Do you have any suggestions to what the issue may be?
- Thank you for the video and your time

Great video brother, simple and to the point!🤙

[stanriley]

Changing the size of jets, metering rods and springs is recommended to try first.

Watching this made me go to national carburetor as well . I got same one too. Question, the fast idle screw is it suppose to be all the way in catching the choke flap ?

[oscarvillarreal]

Did you get this carburetor to work in your vehicle? What would you rather use the Edelbrock AVS2 or Holley Carburator?

[DesertRatFabrication]

Chris, i found the second video where you are drilling the throttle plates, i am watching it now, but might have to come back to it in awhile, have to head to work soon, talk to you soon buddy

I just bought a AVS2 1905 Manual choke and secondary's, putting it on a 1968 Torino with 302. it has hooker headers and a Wieland 8011 intake manifold. not Shure if it has a cam or not, as I did not put in motor. if it does it I a very mild one. so mild mods. Has a C4 with higher 2000-2200 i cannot remember stall converter and shift kit. will b putting in a Posi kit with 355 ring and pinion. if that matters. think it will go on in stock settings ??? Thanks PS bought from same company and it did not come with mounting instructions or bolt tork specs.

I was showing this video to my buddy at work so he can reset his avs2 to factory and start to go leaner from there. And I looked at the view good god brother That's amazing.

Greetings
Great vid-Ty.

At the 3:25 mark, you are discussing setting the secondary flap to factory settings.
After turning the tension screw cc till the flap just touches the airhorn, you then mention to turn the screw 1 full turn; pardon my ignorance, but that 1 full turn- would that be cc or cw?

Thank you

Mine is on a 1966 Plymouth 383 and it backfires when I slow down. In fact, it blew my muffler apart. What could be causing this?

[bentroche]

I have a 83 chevy dually WITH a SB 350 and it has a rv cam...I just bought the edelbrock 650 AVS2
Carb. I installed it and its idling high at 2500 rpm's, could you give me some insight on what to do or how I should adjust the carb. Thank you Sir I thank you for your time and knowledge in advance.

[lilrieffer]

how did that avs 351c go i got a cleveland with holley double pumper but i think my diaphram is blown so i was gonna get a new carb on it

[BloodyHatchetz]

Also I know electric choke is "electric" but does it need to be wired up to work ?

[DesertRatFabrication]

Hi Chris, i found this video very interesting, i thought you did a good job of explaining, i got to be honest i really wanted to see some holes drilled, i will look to see if there is a part 2, i have a 1406 in the 55 truck, i did two videos on the rebuild 1 year ago on my channel, i was able to rebuild it without changing metering rods and springs, i really had no way of telling when i was done if i got ultimate performance, but it was a big difference between before and after, i would like to learn more about the AVS, sounds like a really good carb

Ive got a 350 vortec, 1;6 rockers, stock lower end high rise intake and headers. Ive got an avs2 that stubles when i first hit the accelerator. I can ease into it and it runs great! Any advice?
