Edelbrock Booster Tech: How They Work, ID & Modifications 

Good verbal information even without the dancing hand. About 2/3 way thru the air bleed/idle restriction information and demo is the best part.

Can the AVS2 booster and venturj be used in an older AvS? Both are the same cfm

That's cool how you cut that carb in half to show how it works.

I emailed you a while back and asked about this information. Thanks for the video. Keep them coming

this is the kind of content i'm here for. excellent info!

wow, that was deep. how to tune a booster? that was something I did not know you could do. Very cool.

Concerning the idle air bleed wire restriction mod: I'm running the avs 2 on a small block mopar, w150 granny gear 4 speed. Cruise mode afr reading is 13 ish....highway speed is 13 ish. Throttle response is great. In 4th gear below 30 mph around 1200 rpm it runs rich....high 11s to 12 on afr. Would enlarging the idle air bleed hole solve this issue? Always like your video content, very educational

OH YA

Running a 1901 500CFM AVS2 with annular boosters and a Progression Ignition HEI on my 67 Malibu's 350 Vortec headed cruiser. EFI manners...

5:35 not the obvious big hole where fuel comes from. It looks like the pieces have been cut ,towards the top of the piece where the cut is. why is the hole on the right so much smaller?

I know you're discussing eldebrock carbs but I have a question have you ever seen I believe a holley economaster 2bbl carb very strange looking boosters I use to swap them out when that beautiful variable venturi carbs were junk I meant king lol,?

I love all this edelbrock info!! Im building back up my 77 power wagon ( total trail truck) and rebuilding the carb and tuning it will be a big part after its running.... i used to rebuild all the carbs for my buddies back in the high school days, so i know my way around thez things, but watching your videos is such a refresher.... i got an old 1411 that im gunna put on a magnum 360....should be a runner Thanks for killer videos!

Ok I have a 1411 & I have a 1407. I always thought they were the same carb but with a different tune? Someone told me they have different boosters? I also have two 4x4 ford trucks. One with a 466 & one with a 390. I always ran the 1411 on the 460 but really it was always rich. I'm now learning to tune. I am now running the 1407 on the 390 but with a manual choke & I bought a calibration kit for the 1407 & I was expecting it to be very rich like the other one was on my 460 but it really wasn't far off? I first leaned it out & it went very lean. So I richened it back up & it's not far off from were it started? Alil bit but not far. It runs amazing! I think my 390 truck with that 1407 will out run my 460 truck with the 1411 & the 460 has a bit more speed parts in it! Anyway, what is really the difference in these two carbs? Both 750's? Is it boosters?

Do you have a email or a way I can contact you ? I've been working on building some custom edelbrock carbs and I'd love to send you one to see if I'm making gain or just screwing up good carbs . Let me know , I'd love to send you one .

I see adding the wire to the idle air bleed will richen the idle circuit. I need to lean out the idle circuit as I'm running 14.0-14.5ish on the wideband/afr gauge with roughly 1/8th to 1/4 turn from full stop on the idle screws and just off idle I'm running 12.0, it then leans out to 13.5-14.0 at cruising speed. I'm assuming enlarging the idle air bleed hole will accomplish this?

Another great cutaway and with so many takeaways as well. Love the contdnt and the info! Cheers!!

Awesome video man!!

You're definitely the master of carbs and there tuning another awesome video for sure, would love to see a update on the Chevelle and the GMC engine rebuild keep the videos coming

Cool video. Would you advise on cleaning up the boosters?? Like removing the casting flash, etc to improve them

Another informative video, does the annular booster address the Edelbrock bog?

Yeah great info.
