I saw another video where the crossover was filled in, and the dual feed was used to supply fuel to both bowls. Any experience with this mod? Recommended or waste of time?
I switched to TB FI for my daily driver for better drivability but I sure do miss tuning carbs - I like the hands on carb tuning/rebuilding. Love your videos, keep 'em coming. Oh, almost forgot, how do you adjust carbs to compensate for ethanol in gasoline?
Generally you’ll go a little fatter than we did 20 years ago before ethanol. It’s why I love tuning with an AFR. Makes that process so much more precise and way quicker. Though E10 isn’t that much more to compensate for. It’s the other junk it drags into the fuel system that really plays havoc with a carbureted system. Thanks for stopping by!
I'm going to do this off-road upgrade to an AVS 2 1906. What would you recommend for jetting? Or should I just stick with what it comes with? I'm at 700ft elevation, but can get to about 6-7000ft in the mountains around me. I just wanted to see if there's a certain jetting that would be good for both ends of those elevations and in the middle? Thanks!
Great video. Always in off road on-road scenarios...definitely will be upgrading mine. 👍Looking to purchase a dual AFR setup. Have seen several, which one is a good accurate AFR setup? Appreciate your help.
It’s painfully expensive, but FAST makes a killer dual O2 that’s Bluetooth capable so you read the output on a app on your phone and can use it under hood, in the cab, anywhere around the vehicle. I have their single O2 Bluetooth and it’s extremely valuable when tuning/driving.
@@MuscleCarSolutions I did see that. although mathematically 650 should be plenty for about 5000 rpm on a 440. I didnt see the 'offroad' version of the avs2 in anything larger, I'd have to convert a larger one on my own.
I have an edelbrock 1906 AVS2 on my 77 Chevrolet pickup, my idle is perfect at 14.0-14.5 on the wideband, "cruise mode" is right around 13.5-14.0, "Power mode" around 13.0 and WOT at 12.5-12.7. All of this is perfect in my opinion BUT, right off of idle, think going down your driveway at 1000-1200rpm, 5-10% throttle, my wideband drops to 12.0 and stays there until I get up above 1500-1800rpm and 10-15% throttle, it then leans back out to 13.5-14.0 I've messed with timing, rods/jets, everything I can think of but can't seem to get that spot to lean out any. Somebody suggested the idle air bleeds are too big or too small, can you elaborate on the idle air bleeds and how to correct this issue? Thanks!
Watching the video and doing the same job to my abs2, but my nozzle doesn't have those two brass protruding pieces on it, is that normal instead? I'm talking about the first mod in the video. Instead it has this brass double winged plate that goes over it that the bolts go through. Mine is an AVS2 1906, it's about 3-4 years old I think.
Good video as expected, but yes I noticed the chrome carb but I have driver quality cars and trucks, not show. As a matter of fact last year at Iola car show, new rule to keep hoods shut. I used to be an avid off roader but not so much anymore. Just one non related question, I have a '77 318la all stock except intake and carb. and dual exaust. Intake is stock 360 cast, and carb is eddy avs2 with 4bbl disconected. Currently is jetted to the leanest setting in chart and still is rich, Do you think I can put say a 098 jets in primary and get it closer? I watch for a used 500 cfm avs2 but dont really got 400 bucks for a new one. I was trying a thermoquad, but seemed to have better luck with the avs2 on adapter. I have seen vids say run a spreadbore on a spreadbore intake. Have a good day, Will probably try jet change today, pretty cold here in wisconsin. I do have various jets and rods for the thermoquad.
OK, I'm back, took carb off and I'm suprised it ran as well as it did. Found floats a little high, and almost forgot to check but did, I took accelerator pump squirter off, and no ball and weight, that explained running rich. Your vids made me look. Runs good and sounds better! Still would like your thoughts on thermoquad vrs edelbrock. Looking today the venturi area looks way tighter on the smaller primary thermo, edelbrock has much larger primarys, I'm looking for performance and economy, (and sounding good!!)
Not a fan of the thermoquad. If you’re comfortable tuning it and that’s what you want, go for it! As far as performance goes, I’d give that edge to the Edelbrock. But that really depends on what you mean by performance.
The 1465 is the spring loaded needle and seat kit. That’s a great place to start. But yes, the spring in place of the weight is also a good upgrade point and it’s only available in the rebuild kit.
@@CJRK83 if you call Edelbrock and ask nicely, they’ll send you one at no charge. Just wait and call later in the week when it’s less busy. Never call a tech line on Monday. Worst day of the week cuz EVERYONE calls after a weekend.
You can try anything you’d like! Completely up to you. Maybe it will work, maybe it won’t. I just gave you the recipe to the best tasting cake we could make. If you want to leave out an ingredient, it’s your cake!

I knew about the spring loaded needle and seat, but i didnt know about the accelerator pump spring.... thanks!!
Yeah that one will get you when you least want it to!
Lots of great information in this video, I can fine tune my 1971 GMC Jimmy with a Edelbrock carb keep the videos coming
Thank you sir! Would love to add an early Jimmy or Blazer to my collection. Absolutely love those.
Thanks I’ll definitely give it a try!

So with this mod I would be able to go off camber?
i didnt know about the squirter trick. thats a good one. i do like that black chrome carburetor!!!!!!
It works well in an off road set up for sure. For sure the new black plasma finishes look amazing!

@@dantheadventureman way too many variables. Just follow the tuning chart and it will tell you what it likes and what it wants.
Great video Brian, I’m calling it the spring & the bling, ha ha, catch you soon buddy
Thank you sir! Always good to see you stop by! Hope all is well in the PNW!
What wood you recommend for off roading for a AMC 360 RV cam exust single palm manfold manual transmission in a fsj Jeep
If you check out my video on how to chose the right size carburetor, you’ll find there’s a little more info needed to make that recommendation.

I have an old dodge crewcab with a 440 in it, Im trying to figure out if the 650 offroad avs would be sufficient.
Check out the video I did on how to choose the right size carburetor.

@@MegaMarclar if you’re keeping the rpm’s down, the 650 should be very responsive when tuned properly.

I addressed that scenario and a reversible modification that can be made in my recent booster video.
They ARE currently $460 for Man Choke & $495 for Electric . Was hoping for a Black version of the Off Road.
I’ve heard there are some new black plasma products that will likely be released at SEMA this year. We’ll have to wait and see.
I just got one can't wait to do these mods for my apache
O cool , that would make one awesome off-road kit though ...
I’ve got a rock crawler with a Holley 4 barrels is there a good kit for it?

This was PERFECT! I wish I had this vid back when I had that '79 Powerwagon lol. Great info as always. Thanks for the vid
Go get another Powerwagon and you’ll be good to go! 😆 Thanks for stopping by! Always appreciated.
@@MuscleCarSolutions Don't think for one second I haven't been tempted. BUT, I do have one amazing project that will be coming up soon.
Can’t wait to see what’s next! The bike build has been amazing!
@@MuscleCarSolutions Finishing up a new work bench and starting on the T100!
One of these days when I can finally get a shop built, I’m quite sure I’ll end up looking for a 40-60s bike to add to the collection!
Great info always.
Thank you sir. Appreciate you stopping by to say hello!

I just bought my AVS2 carb, do I still need the rebuild kit? I do have the 1465 offroad jet kit.
The 1465 is the spring loaded needle and seat kit. That’s a great place to start. But yes, the spring in place of the weight is also a good upgrade point and it’s only available in the rebuild kit.
@MuscleCarSolutions thank you for the guidance. I will source the spring and get this all set up.
@@CJRK83 might try it first with the needle and seats. But most of the time the spring on the nozzle check ball is needed as well.

@@MuscleCarSolutions excellent, I will try that and see how it turns out. Thank you again.
Can i just get away with the needle and seat for off roading on the avs2? Or do i need to get the rebuild kit also and install the spring?
You can try anything you’d like! Completely up to you. Maybe it will work, maybe it won’t. I just gave you the recipe to the best tasting cake we could make. If you want to leave out an ingredient, it’s your cake!
@@MuscleCarSolutions well thanks for the info.
