The small screws with the lock nut are importantly to properly tune umpire carbs. They balance the thoat air intake and they can affect the high performance if one throat is drawing more air. Easy to adjust if you can get to them in the car. Also, if your linkage is not adjusted your carbs will not be in sync when over 3000 RPM’S. Have someone sit in the car and hold 3000 RPM and test that the snails are equal. My take. I have learned to tone my three throat Webers that way. Great starting point I must admit.
"Listen for the idle to drop" I heard it drop. Oh wait, was that the idle dropping, or the bass line of the song dominating the audio track? :P Good information here. Thanks for sharing.
Great video!! Simple and clear explanation of carb tuning. Great closeup, clear video and audio. OK....The gripper for the mixture screw???? Where can I get them for my baby Webers??? Thanks again for your efforts. Safe travels, brother Chuck, Kentucky USA
Thanks a bunch for the tech video. My 914 came with the weber and was no bueno. Ended up getting a rebuild kit because the carbs are made in Spain and weren't available. Good job Jason.
dont know if you guys gives a damn but if you guys are stoned like me atm then you can watch pretty much all of the latest series on instaflixxer. Have been streaming with my girlfriend for the last few days xD
@mdecoma yes. The manual says to go back in a 1/2 turn. I usually stop when thebengine is running it's smoothest. As long as you're close it'll be fine. The goal is to get them all in the sweet spot so none of the cylinders are lean. That's how you burn a piston.
Great videos !! I bought a 73 beetle with dual empi 34's and I had them adjusted good until I tried to "get them running better", now they suck and I was thinking about ditching them and getting a Weber progressive. Well after watching your video I realized that I forgot to pinch off the balance tube 🤦🤬 !!! So thanks for the reminder, I'll try it again.
Awesome! I really like dual carbs because you get a good balance of fuel economy and performance. Those progressives have always given me problems so I don't mess with them.
@@OldVolksTV well I really didn't want to get the progressive! These carbs look ancient, I'll try adjusting them again (pinching off the balance tube) and see where I'm at.
I've never really played with them. I would think keeping the chokes synced would be a challenge. None of my dual carb motors have chokes and they seem to do fine, even in snowy weather. You already get more fuel so other than a few seconds of light pressure on the throttle they warm up on their own just fine.
cool video Where can I find those thumb adjuster screws. I was also unaware of the space saver intakes I'm gunna take a look at that. I see someone else already mentioned the links didn't come through.
Hey Jason! Great video! I was curious, if you run a vacuum line to one carb and a balance tube to the other, would you have to clamp either off before balancing/adjusting? Thanks!
I have dual kadrons on a stock 1500 single port baywindow. Seems simple for tuning good video. Other videos i saw they pinch the balance tube, and they use a floating ball thingy on top of carb. Is that needed for kadrons?
You definitely need to pinch the balance tube when tuning. I use a pair of needle nose vice grips with fuel line on the jaws. The "uni-syn" tool is good for getting the flow right. It can be hard on a bus, especially with Kads because of the air filter mount. I've been doing it by ear for a long time and haven't had any issues. If it sounds smooth and revs evenly they're good.
Yes. Start with a warm engine and the screws at baseline settings. With the engine idling, turn the AIR screw IN 1/4 turn at a time until the idle slows down or gets rough. Then turn it out 1/4 turn at a time until you reach the highest idle. Move to the other side and do the same. Repeat the process a few times for the best result.
Thanks Jason, you should get rid of the background music. Also, it would be so much more helpful if would learn and use the proper names for each screw and part you are referencing. When saying “ thingy, this part here, screw “ and then repeatedly using that terminology for all referenced parts, it becomes terribly difficult to follow without replaying the video over and over.
Great video but unfortunately it’s hard to hear the motor idle up/ down because of jamming music .. love it but kinda a little to forward in the mix . 🎸🎸🎸😎
Start with the AIR screws on the outside of the carbs. With the engine warmed up slowly turn them in one at a time until the idle drops. Then turn them out slowly until you get the highest RPM. Repeat on all 4 until the idle changes with a 1/4 turn in or out. That should b pretty close. If it's still rich you may need to play with the jets or check the fuel pressure.

working on a twin IDF40 beetle right now and it’s my first carbed car this helped getting it running right
Thank you for some very clear instructions for the ICT-34's.
My pleasure

the background music really doesnt help at all
Great video man. When I get my bus going I am gonna need this info has dual Webber 40’s.
Yup, this is why I only run one 🤣 thanks for more great info my brother!

Thanks! I think I have a few sets left. Shoot me an email to txoldvolks@gmail.com and I'll let you know what I have.
@@OldVolksTV sent you an email. Thank you so much for the prompt reply.

Thanks! I've had tons of people asking for this one. Dual carbs can be very intimidating, but they're pretty easy if you take your time.

@Gerald Victor yup, have been using InstaFlixxer for months myself :)
@Gerald Victor Definitely, have been using instaflixxer for years myself =)

Great stuff tho the background music could have done with being a bit less ;)
For the big Webers, do you still turn the screw a half turn in after you find the highest idle or is that only for the small webers?
@mdecoma yes. The manual says to go back in a 1/2 turn. I usually stop when thebengine is running it's smoothest. As long as you're close it'll be fine. The goal is to get them all in the sweet spot so none of the cylinders are lean. That's how you burn a piston.
Wishhin i still had my original Kad filter caps n skreenz.

Hey, any thoughts on the CB performance dual Solex carbs with chokes on them ??
I've never really played with them. I would think keeping the chokes synced would be a challenge. None of my dual carb motors have chokes and they seem to do fine, even in snowy weather. You already get more fuel so other than a few seconds of light pressure on the throttle they warm up on their own just fine.
@@OldVolksTV ok thanks, have a great day !!

Thanms! Email me at txoldvolks@gmail.com I'll see if I have any of the adjusters left.
How can I get a gripper turn screw?
Shoot an email to txoldvolks@gmail.com and I'll get you set up.
Hey Jason! Great video! I was curious, if you run a vacuum line to one carb and a balance tube to the other, would you have to clamp either off before balancing/adjusting? Thanks!
You wouldn't get a good vac reference from one carb. If you ran a balance tube you would definitely need to pinch it to adjust them.

@@OldVolksTV thanks for that👍👍👍👍👍
@@OldVolksTV …on the bus video w/kaddie segment,..did you first start by turning clockwise?,.then counterclockwise, followed by 1/2 turn in?
Yes. Start with a warm engine and the screws at baseline settings. With the engine idling, turn the AIR screw IN 1/4 turn at a time until the idle slows down or gets rough. Then turn it out 1/4 turn at a time until you reach the highest idle. Move to the other side and do the same. Repeat the process a few times for the best result.
When you say you will notice no difference, do you mean when screwing the mixture screw in half a turn?
Thanks
Thanks
Thanks for watching!

Nice video
Thanks for watching!
Where did u get those knobs for mixture screws
I make them. I have a few sets for the ICT (baby webers) ready to go. Shoot me an email at txoldvolks@gmail.com
I love the music 🤟🤟
Is that turbo motor staying carbureted or are you going EFI
Just EFI for now
Where did you get that air fuel mixture screw thing, not sure but I want some.
@joshgreenwood2412 I make them. They work on ICTs. I've sold a couple sets to be used on IDF but I haven't tried them myself.
@@OldVolksTV how can I get a couple
@joshgreenwood2412 send an email to txoldvolks@gmail.com and I'll give you the details.
Thanks for the video, what happened to the links🤔
🤔 they must not have loaded. I'll see if I can add them now.
nice job man!
Webber windows are not necessary all you need is skill
How about making a video on how you tune your dual carburetors in the engine bay??
Great video but unfortunately it’s hard to hear the motor idle up/ down because of jamming music .. love it but kinda a little to forward in the mix . 🎸🎸🎸😎
I have a weird question, my engine is running really rich with the dual Webbers, what adjustment is that
Start with the AIR screws on the outside of the carbs. With the engine warmed up slowly turn them in one at a time until the idle drops. Then turn them out slowly until you get the highest RPM. Repeat on all 4 until the idle changes with a 1/4 turn in or out. That should b pretty close. If it's still rich you may need to play with the jets or check the fuel pressure.
👍
yo, the metal music is distracting..
you should nix the background music for the tune-ups. can't hear the engine running on it's own. Else this is really great . thx !!
Yeah, in hindsight I realize that.
So what do I have to do if my engine is running to hot?
Hot can mean it's running lean, or the timing could be off, or the valves could be tight, or low on oil. Or the oil cooler is clogged up.
why the crazy music !!
nice vid but could have done without the music over the actual tuning part.
All I can hear is the stupid background music playing. I don't need to be all fired up to watch a video.
