Thank you so much for posting this dual carbureted video. I was feeling discouraged about my vw and a bit overwhelmed as I am a first vw owner as there were not many videos out there covering this topic
@@ChrisSustayta you’ll have to figure that out as you want both sides to be the same. It’s not about the number as long as they both match and your idle rpm is where you want it.
Thanks man , great vid - i’m new to dual webets so this was very very helpful - much thanks . I would really like to have been able to see the exact adjustment screw you turned on your carb - i still don’t know which screw to adjust but i guess i’ll look for another video contributor who may show that exact adjustment screw - Thanks again Man
On the side of the carb that faces outwards, there’s a mixture screw for each barrel. If you have the same IDF carbs, there are 2 on each carb. Hope that helps 🤙
Thank you for the Awesome video helped me understand better. Can you explain how the snail meter works? Like why did you set it to 4 and what that represents? Also where do you buy them. I have a 2110cc engine in my 67 VW bug with 40 weber's
@@offensivegamers1440 glad the video helped you out! The snail can be purchased at most any VW supplier. What you’re doing is measuring the airflow on each cylinder to ensure the carbs are pulling in the proper flow so they are balanced. Don’t worry about the number 4, every engine will be slightly different. Dial in your carbs via rpm, lean beat idle, timing, etc. Then use the snail to make the necessary adjustments to make all 4 carb throats the same number. If the front and rear are slightly off and it’s running smooth, don’t stress it. You’re mostly measuring the left and right carb.
I liked and subscribed. I watched the entire video. You are great at explaining things and generous with your time, which is why I really thought you were going to show me how to adjust the carburetor. I see your hand moving on something in the back but you never said or showed what it was.
So many questions, so little time.I don't think I've ever seen this done before. I have to ask, WHY? 1) I SEE THIS ALL THE TIME. WHAT MAKES THESE GET OUT OF SYNC? 2) IS THERE ANY WAY TO AVOID THEM FROM GETTING OUT OF ADJUSTMENT? 3) HOW DO YOU KNOW, OR WHAT DOES THE CAR DO DIFFERENTLY TO LET YOU KNOW THEY NEED ATTENTION? ITS MIND BLOWING TO ME THAT THESE CARBS WORK GREAT AND ARE A BIG HELP TO THE VW ENGINE. YOU WOULD THINK OVER THE YEARS SOMEBODY WOULD HAVE CAME UP WITH A SYSTEM TO TUNE THEM ONCE AND BE DONE. I COULD SEE MY OCD KICKING IN WITH THESE. I WOULD BE OUT THERE EVERYDAY ADJUSTING THEM BEFORE LEAVING THE DRIVEWAY. GREAT HOW TO VIDEO. - KEEP DUBBING -

Great video. Im still a bit confused; when u use the snail to compare the right front barrell, versus the right rear barrell,…how do u make them the same?
Thanks! I’m not too concerned about the front and rear barrels being the same as I’m looking for the same change between the front and rear. Most people I’ve seen don’t even look at the rear barrels, they only compare the L&R front barrels which is what you’d compare to sync the carbs. IF the front and rears needed adjustment, you’d need to adjust the butterflies in the carb. There isn’t an adjustment knob for that.
@@VWJawbreaker ok makes sense. Also, i currently have the boxy style fan shroud with the 2 openings for the air. Is it better to change to the rounder fan shroud, in order to clear the carb. I see some videos that require putting dents into the shroud for fitment.
@@tomasalvarez6040 yes, the 36hp style shroud does give more room for the dual carbs. I ran dual carbs with a stock shroud without issue also. Personal preference and intake manifold style plays a role.
good vid man. i adjusted mine the other day but missed a crucial step.I didnt disconnnect my linkage and so now my idle is way too high. its running good but scary to drive lol. im going to go out and redo it now. thanks!
I just didn't understand what you turned on the carb to adjust. would be cool to see the carb adjustment screw even if displayed on another carb , so we see what exactly to turn
Makes sense and I’ll try to redo the video at a later date. You’re turning the mixture screw on the side of the carb. There’s one per cylinder on dual carbs.

Great video. Here's an idea for a new video,that's not available on TH-cam yet. Install a wideband to fine tune those IDF carburetors. You'll have to change your exhaust system to a 4 into 1 header,but your engine will run better and use less fuel.

Great video! I do have a question I legit thought the idle mixture screws would play a part in the sync process? How do you know you have the idle mixture screws set properly?
Kevin Hamling usually the engine will run rough and not sound smooth. That’s usually due to one carburetor not being in sync with the other causing one side of the engine to run at a higher rpm than the other. Thanks for watching!
@@VWJawbreaker so if one side is running at a higher rpm does that mean the crankshaft is broke? I dont see how one side can run at a higher rpm than the other side. One side can run with more piston force but not higher rpm
Zundfolge1432 one side will not necessarily run at a higher rpm, the side with the higher idle will “carry” the rpm load more than the other side. That’s what causes a very rough idle and off sound.
@@VWJawbreaker ok yes that works. I had dual dellortoes 36, gave up on them after a while but spent hours playing with sinc. wasnt satisfied with them. sync at idle yes but ran worse off the line with both linkage angles on both sides equal. Left side had to open slower to make it run right. I never understood why this had to be that way, unless for some unknown reason the carbs themselves flowed differently or maybe ran different air fuel mixes per what ever throttle position they were at.
Zundfolge1432 sound like there was something wrong with the carbs or jets if it ran that way. If the linkage was opening the same amount on both sides and at the same time, then it’s the carbs. They can be a pain sometimes until you get them figured out and dialed in.
Eddie McGregor you can order a snail from just about any online VW parts suppler. The exhaust is home made on this setup. I’ve since upgraded engines and exhaust.
I committed on your past 1915 build. I told you I purchased a 1967 bus that has a 1915 not sure of heads and can tell it has a cam not to big.

As per your procedure is was only able to get the passenger side to a four and the driver side would not come down to a five as I adjusted the carb it’s started to choke out.
Tony Peltier hi there. Yes, that is a fuel pressure regulator with a pressure gauge also. Most carbs don’t like more than 3lbs of fuel pressure, more than that the fuel pump can over power the needle and seat.
I dont know if you'll see this comment, but with the dual carburetors I wanted to know what the gauge you have behind the fan is? is that required for dual carb, I have heard it is connected to the fuel filter. Please let me know.
Hey Remy, I try my hardest to reply to all comments. The gauge on the firewall is a fuel pressure gauge connected to a fuel pressure regulator. It is important for all of the carbs that we run on our VW’s to be at no more than 3psi. With the regulator I can adjust the fuel pressure as needed. The fuel filter in my application is located by the transmission.
@@VWJawbreaker oh awesome, can you let me know where you got yours from? im looking to buy a 71 beetle, and wanted to dual carb it but I keep seeing this gauge on alot of beetles and wanted to know what it was and how it worked.
Ever since I adjusted my valves on the passenger side I hear a clunking noise, could it be that one of the valves might be two tight I gauged them all at .06 with my feeler gauge
@@ChrisSustayta if the valves are too tight, you shouldn’t have that problem. Check your battery voltage, grounds, starter and the power going to starter solenoid.
Im having an issue with my 1835 motor. I have dual IDF 40's and when Im at idle I have the carbs synced perfectly. they read around 6. When I put throttle on it maybe go up to 10 on the left the right jumps to 20. Im suspicious that the linkage bushing on the left hand side is worn . Does that make sense. Ive already checked compression, leak down, had the carbs rebuilt and checked for leaks around the intake manifold and where the carb connects to the manifold. Thoughts? Also Im backfiring like crazy when I take the throttle up.
If you’re having the carbs read that much if a difference, they aren’t synced properly. If both read the same at idle, then it’s your linkage that’s out of adjustment most likely.
It could be the bushings, linkage or a combo of the above. With the car off, adjust the linkage so both carbs open the exact amount at the same exact time. Once they are synced and the linkage adjusted, you can go from there regarding the backfire.
Hello, I have a vw type1 and 1.6 engine I have DRLA 36 mounted and I have a question whether they are adjusted in the same way as you, what are the optimal values on the scale for the carburetor. Answer me how you can
@@VWJawbreaker I was wondering if it has some 'hidden' meaning since Matthew apparently freaked out about it. Maybe he thinks there's something sinister about it? Or is just freaked out by an image? Hopefully he'll chime in.

If your valves are all at .006”, you’ll hear a slight tick but not a clunk.
@@VWJawbreaker clunking as it is trying to start like the starter trying to turn the motor
@@ChrisSustayta if the valves are too tight, you shouldn’t have that problem. Check your battery voltage, grounds, starter and the power going to starter solenoid.
Im having an issue with my 1835 motor. I have dual IDF 40's and when Im at idle I have the carbs synced perfectly. they read around 6. When I put throttle on it maybe go up to 10 on the left the right jumps to 20. Im suspicious that the linkage bushing on the left hand side is worn . Does that make sense. Ive already checked compression, leak down, had the carbs rebuilt and checked for leaks around the intake manifold and where the carb connects to the manifold. Thoughts? Also Im backfiring like crazy when I take the throttle up.
If you’re having the carbs read that much if a difference, they aren’t synced properly. If both read the same at idle, then it’s your linkage that’s out of adjustment most likely.
@@VWJawbreaker Do you think it could be the linkage bushings? Also could improperly synced carb cause backfiring?
It could be the bushings, linkage or a combo of the above. With the car off, adjust the linkage so both carbs open the exact amount at the same exact time. Once they are synced and the linkage adjusted, you can go from there regarding the backfire.
So my 74 westy has ni choke? I jave new carbs. Ill put it on and sync and see if it starts.
Charlie B depends on what carbs you have. Some brands have chokes and some don’t.
VWJAWBREAKER Theres no choke connect to it . Wont start though
Charlie B if they don’t have a choke, you’ll need to press the gas pedal down a little to raise the rpms up until it gets warmed up.
Hello, I have a vw type1 and 1.6 engine I have DRLA 36 mounted and I have a question whether they are adjusted in the same way as you, what are the optimal values on the scale for the carburetor. Answer me how you can
jozek kalata it really doesn’t matter what brand dual carbs you’re using, the process on syncing the carbs is the same.
thank you for your reply.
jozek kalata anytime!
👍✌
I dont know why, but i thought they were adjusted by using the bypass.
Maybe in other applications but not on VW’s.
Some people fine tune the IDF’s with the bypass screw but your main adjustments and syncing should be done with the bypass screws closed.
I was soooo looking forward to watching this video but once I saw that SKULL, I turned it off......
Matthew Isaacs sorry you feel that way but I do appreciate your comment.
What's the significance of the skull?
DonziGT230 none really other than my son picked it out for a bday or Christmas present a while back.
@@VWJawbreaker I was wondering if it has some 'hidden' meaning since Matthew apparently freaked out about it. Maybe he thinks there's something sinister about it? Or is just freaked out by an image? Hopefully he'll chime in.
DonziGT230 no hidden meaning. I do like skulls but not in a cult kind of way..... kids got me the shirt a while back 🤷♂️
To each their own though.
quit looking at your face on the camera look into the lens, you can watch the video later to see how hansom you are.
VW MOSES thanks for the feedback! However I’m only using my smart phone and not a real camera system..... I’m low budget 😂
