Sir. This is hands down the best Weber guide given to date. I am now considered the Weber wizard in my area as so many shops have no clue how to dial these in. Alot of shops just throw these on, truck smelling like a gas station at idle. Your video guide is a blessing, much Thanks. Helped with Toyota 22r, Nissan 2.4l, Raider 2.4l, and mazda 12a Carbed. This is the video fellow mechanics, worth a full watch and take notes.
Your video helped me understand so much. I was adjusting all those screws blindly before on my 1986 Suzuki Samuria, but now I feel confident I can restore everything to the way it should be. Thanks a million for the guidance!
My 87 suzuki samurai has a damn water choke and won't even start unless I pour gas down the throat. Then it will run until the gas runs out. But I know I'm getting fuel to the carb. Guess I'm taking it off and cleaning it now. It's a weber DGAV 4 I believe
Really helpful - Just bought a 1975 VW T2 1800cc with a Weber 32 36 on it. Not mentioned in Bentley or Haynes manuals, thank goodness for people like you, with thanks, Dave.
And... Rebuilt the Weber on my midget. After the very basic breakdown, ultrasonic cleaning, rebuild and somehow miraculously it worked. But then headed right back here to rewatch and relearn everything you taught me last summer.

One second in and I thought I was about to watch Matt from demolition ranch explain cars to me lol. Glad I took a longer look because this video was really helpful
Awesome, thanks!! I did the tuning in 8 minutes on my '77 Corolla. Someone had put a clone Weber some time ago, pulled the timing chain, and never finished. I put the car back together and deleted all of the emissions, added a header exhaust, and converted it to electronic ignition. It fired right up but kept back firing and sputtering. I reset the timing and still very unhappy. I reset the the carb tune as per your video and voila!! I ended backing up the mixture screw a half turn after it was set at 2 full turns and it runs like a champ now!! Thank you sir!!
Truly appreciate the time you took to do this video. I just happened to pick up an old Jeep with this carburetor and it's definitely been many decades since I've had a mess with carbs. Not only good explanations but good videography also
@@williamchase5698 it could be that the idle speed screw is too far in, opening the bottom throttle plate, or the seat is damaged on the mixture screw, or that is a vacuum leak somewhere
MazdaMitch. Thanks for this video. It was super helpful. My car was running really rich and come to find out it was set (by previous owner) 2.5 turns out. I adjusted the carb to just beyond 1.75 turns.
RE: UPDATED FLOAT ADJUSTMENT - I just got off the phone with Weber. The reason behind the floats needing to be adjusted differently in current day is due to the alcohol content in modern gasoline. The early specs were written when alcohol content in gasoline was around 5%. It's now between 15-20%. This affects the buoyancy of the floats, making them less buoyant, which means the floats need to be adjusted 2-3 degrees further into the float bowl than previous spec. In other words, you want to be adjusting the floats 2-3 degrees in the direction that will make the needle push TIGHTER into the seat. My 32/36 has brass floats. The tech told me what he uses as a frame of reference is the tiny white plastic washer at the end of the accel. pump spring that sticks up between the floats (seen at 29:50). The top of the floats should line up with that white washer when they are adjusted to that 2-3 degree change, without any load on the float spring (like you mention). Again, that washer trick is for the brass floats, I'm not sure about the black foam floats. Call them. They are very helpful!
20 years on mine still running great to this day ,,,,,rejetted it back in 2005 and that was it ,,,,,they are pretty good carbs in my view ,,,,,god bless
Had to mess with it 3 times, but the idler jet had a little bugger in it that apparently I could not see. Wire brush hair was the only thing that got it! THX MITCH
Just got a 32/36 for my 1980 VW Dasher, watching this to prepare. Love the video, high quality close ups and simple explanations plus a few amusing edits.
Great video- and great message about why you did this. I have an '84 CJ7 -258-4.2L- (Not a Mazda Guy--- but I love my rig just the same)- Wanted to install and adjust a Webber 32/36 to replace the stock - yes-'84 stock carb. -- Thank-you for all the info- calm, clear and concise- - loved the rain on the roof too.
Just wanted to say thank you for the great video, I have a 87 Jeep and I use this same carb on it, when I got the jeep the carb was loose, so I had to readjust everything, this made was a great help.
Excellent video thanks. I’m more confident to work on my 1960 Morris Minor running a 12a Nissan motor with a 32/36 Weber now. Thanks for making such an informative video.
Thank you so much for such a detailed video. I never thought I'd sit through an hour long video on carbs but it was really helpful the way you explained everything. Thanks for the jibber-jabbering. Really appreciate it. Looking forward to (attempting) to adjust the weber on my 1979 ford escort. Thanks from New Zealand!
Thank you!! I’m Setting and resetting an older Weber 32/36 on a 22r Toyota. With your videos i am starting to learn this carb and all it’s parts. Im trying to dial in the choke still. Keep the settings and tuning videos coming! Just subscribed.
This was very helpful thanks! I’ve been so nervous about setting up my Weber this year that I’ve held up the progress on my 92 Going to have it running soon!
Thank you thank you for sharing that knowledge! I'm Working on a 73 baja bug with Weber a Progressive 32 36 DF AV. I know nothing about carburetors (im used used to ecotec 2.0 / FI) but i'm learning and gathering info to keep this air cooled engine running. I like it. It just smells really really rich though.
Thank you for your video sir, I know your video is for Mazda 32/36 but I purchased a genuine Weber for my 85 Nissan 720 this helped a lot on tuning my carb, my old OEM carb was on its way out dieseling really bad, put the Weber on after operating temp was good idle amazing but when I took it for a spin she continued to diesel not as bad and is hesitating to start have to pump the pedal but if I let it sit over night she’ll start and idle just fine with no issues without pumping the throttle but once it gets to temp it starts to mess up, but like you said in your video I’ll check timing next 👍
These are great videos - I appreciate it. I’m not familiar with this at all and my new boat has this carb on a Volvo penta marine engine. I start right up but after hot died on idle - so based on your video I’m thinking I need to play with the choke.
@32:47 they probably used a different float for the initial instructions (Brass) Plastic is the new norm. Only 2mm of float travel from closed to open? Wow, that is tight. Great video!
I'm about ten mins in and thanks alot I've learned alot .... but I have a 86 b2000 was running fine and one day it started cutting out going down the road but would ideal perfect I've cleaned and opened it up but everything looks good .. could u do a full rebuild video
pro tip about that choke linkage circlip: I just took it off ages ago. Unless you pry that linkage, its not coming off that pin or binding. Never had any issues since then. Makes tuning much easier.
45 years ago, the idle jet would clog up on mine. I would back down a hill, turn off the engine, shift to second, close the choke, and release the clutch. Boom idleing again! For a month or two. I miss that 850!
I learned a lot actually within the first few minutes so thank you because everytime I’m pushing slightly on the throttle it sounds like there’s a lot of air going through so I’ll adjust the mixture screw and see if that changes anything! Also I didn’t wire the choke so that could be a possible problem as well
I’ve been having nonstop problems with the Weber I put in my 87 Toyota pickup. Most of that was vacuum leaks, but I’m confident this video just pointed me in the right direction. Thank you. Only thing that’s throwing me off is that I had the fuel mixture screw turned all the way in and it was still running. Maybe I did something wrong somewhere.
You probably had the idle speed screw turned in too much and the plates at the base of the carb were opened up some because of that. Idle speed screw and idle mixture screw are two different things.
@@MazdaMitch yeah I get that they’re different, but you’re saying that the idle speed screw being too high would allow fuel to get in even when the fuel mixture screw is turned all the way in?
@@MazdaMitch appreciate it. I adjusted the choke, and it seems to shift better now. Not great though. If I’m trying to go uphill in first gear, I need to get a running start, and it pops like crazy from the carb. That’s my biggest issue right now. The popping, and the inability to go uphill easily. Fuel regulator is set to 1psi, but I’ve played with that a little and can’t find a sweet spot. Just constant popping when I start off in first, and when I get the rpms too high. I’m really leaning towards a vacuum leak that I’ve missed somewhere, but I was hoping carb/ fuel adjustment would fix it. Either way, your video did help me understand my carb better, and I thank you for that.
One PSI seems extremely low I don't even run a fuel pressure regulator why don't you remove your fuel pressure regulator and increase your timing to about 12°, it'll probably solve all your problems.
Thanks for the video, great information! I am trying to adjust the idle speed screw with the carburetor installed on my J10 Jeep FS 1974 but it is hard to get to it. Any suggestions? Thanks
Thank you so much for this video. I have the same Weber carburetor on my 92 isuzu pup, I took a trip from Houston to San Antonio and back to Houston, went I got home my carburetor is making a loud whinging noise and back fire through out the carb and runs bad and stalls, any suggestions? I checked everything to see if I had a vacuum line busted, I added a new distributor cab, rotor, new cables , and new spark plugs.
Sounds like a vacuum leak, could be at the base of the carb, Check it to see if its loose or take it of and reapply new gaskets and use permatex high tack like I did in the how to install a weber video
Can someone tell me, I am a newbie and know very little about cars. I have an MG Midget with weber carb 32 dgav 5e. There is no idle mixture screw. Port is there but no screw. (Can't see down the hole to see if it is tapped) My plugs carbonize in only a few miles. Very poor mpg. Does this model not have an idle mixture screw ? Any help from anyone?
Great video! Thanks for the deep dive. Pretty sure you've solved my problem on my 38/38 DGES that I have in my '64 F100. Need to adjust that choke so the choke valves stay open when the throttle is pressed. Dang thing is stuck in fast idle mode. I'll find out tomorrow!
i got all mine hooked up and set everything. but when i gas my car all the way to the floor it starts popping and what go no where.but will run good half way down. anybody know what it could be?
On my website I have some Weber Docs, www.mazdaminitruckin.com/info/weber-info and on the one that says How to Setup and Tune Your Weber, it states this at the top. "It is important to verify all linkage and levers are installed without binding and the linkage opens to full throttle and closes to the Idle Speed Screw. The number one and two reasons for tuning errors are improper linkage installations and over tightened linkage nut, causing a binding in the linkage assembly."
Awesome job with the video I just got a truck with the same carb and I’m going to check the idle and choke Can you tell me the best way to run the wire for the electric choke I know it needs to be fused but since it’s a power cable I should run it from the ignition switch cable ? Thanks
Hey, I’m stuck, idle mix all dialed in. Problem is it won’t throttle up. 2 carbs I’ve tried and both die when I throttle up. One is new one is used, same issue
Maybe you mean bog down when you give it a lot of gas? And it's happened on two different carburetors so the problem probably is somewhere else. You could have clogged up exhaust or your distributor may have the vacuum advance disconnected or connected in the wrong place
Tip - choke gets "warm" simply by the power being supplied, so you can bench "warm up" the choke just by applying voltage to it, if you want to adjust the choke at "full warm", just leave it connected to 12v for a while before setting rotation.
I have twin Weber’s on my Triumph TR7 ... so double the trouble. Thanks for explaining that capping the vent will prevent gas from evaporating out of the bowl. I only drive this car on the weekends, and it always takes a lot of cranking to get going. I thought maybe somehow my manual fuel pump was letting fuel seep backwards. This makes way more sense. Thanks
I make the Weber carburator on my mazda 89 but I don't know what to do with the third line besides to fuel and fuel return or just let like it is, help please
You may be referring to the vent line, if so just tuck it back. Need more help and a place to post pictures, join our Facebook group. Link should be in description of video.
Sorry if I missed it, but what is that scre just above the throttle? The long one sticking out close to the idle screw, running perpendicular to it? Is it also a jet? And if so I'm guessing it gets tightened down all the way?
So I'm not very automotive mechanical inclined. I just put a Weber on my 82 Honda Accord cause I got tired of messing with all those airlines. I need the bigger carb chamber over the bigger manifold correct? Or does it not matter?
This video has been a huge help. Thanks so much for sharing it. I don't know about everyone else, but I don't give a damn how long a video is if it's full of useful information like this one was.
Why is my lever the one the screw pushes far away from the screw its a brand new weber never used and the screw has to turn almost all thecway squeezingvthe spring to reach it.
1977 20R toyota CHINOOK RUNS 👍STARTS RIGHT UP..... AFTER 3 store stops warmed up idle high like choke not shut down or throttle stuck. I read about throttle screw..... I read about fast idle screw. Any advice? Wish I could afford WEBER 💋😘
Well don't confuse the idle mixture screw for the speed screw which controls the idle of the engine. Sounds like you need to back off the speed screw, not the idle mixture screw.
Truck seems to run fine but I have some soot on my exhaust connections. I tuned it years ago and left it. Do I need to start my tuning from square one or can I start with the mixture and then idle again
2 thumbs up ! Thank you, Thank you, Thank you, my mom has a Mk2 Escort 1600 auto, and suddenly its just running extremely rough, I've cleaned the carb, bought new boogie cords, new spark plugs new coil, but it is running so rich, the spark plugs are black like charcoal, and the car is giving me about 7 miles /gallon. It's funny how a car can untune itself, but now I think I know exactly what my problem is.
Mitch, loved the video…do you know anyone to take my Weber for tuning in Charleston, sc?.87 dodge Raider 4 cyl. Truck stalls when stops and then hard to start

@@jonbertocchi173 ohh, wow. I wouldn't have thought they'd be checking for emission equipment from the 70's.
Truly appreciate the time you took to do this video. I just happened to pick up an old Jeep with this carburetor and it's definitely been many decades since I've had a mess with carbs. Not only good explanations but good videography also
Very welcome thanks
@@MazdaMitchso if you turn the idle mixture screw all the way in and it doesn't affect the idling at all. What would that indicate?
@@williamchase5698 it could be that the idle speed screw is too far in, opening the bottom throttle plate, or the seat is damaged on the mixture screw, or that is a vacuum leak somewhere
@@MazdaMitch it was the idle speed screw...... you're a lifesaver! Thanks.
Thanks! I recently converted my MG to a 32/36 Weber, and your video helped me to understand it a lot better.
Best, very educational presentation. I'm setting up a Weber 32/36 & this video sure comes in very very handy. Thanks!
Appreciate that! Glad it helps!

The only thing missing in this video is when you have dual carbs, but thats me. I'll do my best as is. Great information. Simple and to the point.
Not a lot of mazda b series guys are running dual carbs.

Thank you for all the informations that you provide and help us rookies. Respect brother🤙
Thanks for the insight, I'll be trying this on my 4AC after work to hopefully mitigate the problem I have. I'm running wayyyy too rich
pro tip about that choke linkage circlip: I just took it off ages ago. Unless you pry that linkage, its not coming off that pin or binding. Never had any issues since then. Makes tuning much easier.
No sir not doing that my look something would bind up.
Thanks, I deleted emissions on my 90 isuzu. Runs great with the stock carb, but I ordered a Weber 32 36 as they are far less complicated.
You are a genius 👏!! Thank you for the tip of double cleaning the idling jet , it works on my weber 30 DIC on Fiat 850 coupe
45 years ago, the idle jet would clog up on mine. I would back down a hill, turn off the engine, shift to second, close the choke, and release the clutch. Boom idleing again! For a month or two. I miss that 850!
if there is no wire to the choke will it run at all. thanks for the video. showmehow
The choke will never open up and it will stay choked starving the engine of air. Find you a 12 volt source on the passenger fender well and hook it up
Thankyou, very helpful!
Thank you so much for these video bought a hoodie and a shirt. Wish I could do more.
You can! My videos now have the Super Thanks under the video for tips!

My weber says weber North America.I done my swap on my Mazda b2000 and never did a Egr block off.Could this effect tuning?
You could have a vacuum leak somewhere like near the EGR. Any leak will affect tuning.
Just bought an 85 nissan pickup. It has a weber that doesn't idle. Gonna try this. Thanks for the video.
Can someone tell me, I am a newbie and know very little about cars. I have an MG Midget with weber carb 32 dgav 5e. There is no idle mixture screw. Port is there but no screw. (Can't see down the hole to see if it is tapped) My plugs carbonize in only a few miles. Very poor mpg. Does this model not have an idle mixture screw ? Any help from anyone?
Excellent description and break down. Thanks a bunch for the video
Video was mint man, helped me loads getting ready for my own 32/36 Weber on my 1.6 suzuki vitara
Cheers
Great video! Thanks for the deep dive. Pretty sure you've solved my problem on my 38/38 DGES that I have in my '64 F100. Need to adjust that choke so the choke valves stay open when the throttle is pressed. Dang thing is stuck in fast idle mode. I'll find out tomorrow!
i got all mine hooked up and set everything. but when i gas my car all the way to the floor it starts popping and what go no where.but will run good half way down. anybody know what it could be?
Mine as well
Thanks for Posting this ! Helped me a lot !
Do you have any clue why my throttle would be extremely stiff on a new carb?
On my website I have some Weber Docs, www.mazdaminitruckin.com/info/weber-info and on the one that says How to Setup and Tune Your Weber, it states this at the top.
"It is important to verify all linkage and levers are installed without binding and the linkage opens to
full throttle and closes to the Idle Speed Screw. The number one and two reasons for tuning
errors are improper linkage installations and over tightened linkage nut, causing a binding in
the linkage assembly."
@@MazdaMitch thank you so much! I will try it when I get home!!
Awesome job with the video I just got a truck with the same carb and I’m going to check the idle and choke
Can you tell me the best way to run the wire for the electric choke I know it needs to be fused but since it’s a power cable I should run it from the ignition switch cable ?
Thanks
It needs a 12v keyed on source . I find and use one from one of the plugs left over on the passenger fender well
This guy is the shit he makes it easy for regular people to understand what’s going on keep up the vids !🤙🏾
Thanks a lot for this useful information. I got my car running a bit nicer because of this =)
Glad it helped!
Hey, I’m stuck, idle mix all dialed in. Problem is it won’t throttle up. 2 carbs I’ve tried and both die when I throttle up. One is new one is used, same issue
Maybe you mean bog down when you give it a lot of gas? And it's happened on two different carburetors so the problem probably is somewhere else. You could have clogged up exhaust or your distributor may have the vacuum advance disconnected or connected in the wrong place
Damn good video. Loads of info that I previously didn't know. 1992 Isuzu pickup.
S’good! I needed this video, thanks! Mine is on a 1973 VW Bus 1.7 engine
Thank you for your Gift
Great video. Thank you.
Thank you for your videos!
Excelente video unfortunately I am not Ebla to fix my back fire I’m timed but I don’t know what I’m doing wrong
Tip - choke gets "warm" simply by the power being supplied, so you can bench "warm up" the choke just by applying voltage to it, if you want to adjust the choke at "full warm", just leave it connected to 12v for a while before setting rotation.
I have twin Weber’s on my Triumph TR7 ... so double the trouble. Thanks for explaining that capping the vent will prevent gas from evaporating out of the bowl. I only drive this car on the weekends, and it always takes a lot of cranking to get going. I thought maybe somehow my manual fuel pump was letting fuel seep backwards. This makes way more sense. Thanks
Thank you sir. Great informational video. I appreciate you taking the time to put all this information out there.
I make the Weber carburator on my mazda 89 but I don't know what to do with the third line besides to fuel and fuel return or just let like it is, help please
You may be referring to the vent line, if so just tuck it back. Need more help and a place to post pictures, join our Facebook group. Link should be in description of video.
@@MazdaMitch thanks 👍
Sorry if I missed it, but what is that scre just above the throttle? The long one sticking out close to the idle screw, running perpendicular to it? Is it also a jet? And if so I'm guessing it gets tightened down all the way?
Can you provide a time stamp at what you're talking about?
@MazdaMitch I guess you can see it pretty well at 1:05:15. Just above the threads that the idle speed screw screws into
@@codeguiseit's just a plug or Port I think you can remove it and it will allow you to have a vacuum port
@MazdaMitch ah okay great, thank you!
I changed the jets in my Weber carb for high altitude jets. My truck is running amazingly better now
So I'm not very automotive mechanical inclined. I just put a Weber on my 82 Honda Accord cause I got tired of messing with all those airlines. I need the bigger carb chamber over the bigger manifold correct? Or does it not matter?
No idea it's not an 86 through 93 Mazda truck so I don't know what you're dealing with
This video has been a huge help. Thanks so much for sharing it. I don't know about everyone else, but I don't give a damn how long a video is if it's full of useful information like this one was.
Why is my lever the one the screw pushes far away from the screw its a brand new weber never used and the screw has to turn almost all thecway squeezingvthe spring to reach it.
Your throttle shaft that the throttle cable is connected to is too tight or binding.
@@MazdaMitch there was a screw on other side that i turned and it made it closer to the screw...thanks
1977 20R toyota CHINOOK
RUNS 👍STARTS RIGHT UP.....
AFTER 3 store stops warmed up idle high like choke not shut down or throttle stuck.
I read about throttle screw.....
I read about fast idle screw.
Any advice?
Wish I could afford WEBER
💋😘
Check the throttle shaft to see if it's too tight. Check the website mazdaminitruckin.com and read the Weber doc on how to tune
@@MazdaMitch where is throttle shaft on a Aisen Carb. 20R toyota Engine if U can, please teach me.
💋😘 UR HELP APPRECIATED.🧑🔧🙋♀️
@@lindaleehulsey3167 I dunno, look it up online. Im a weber guy.
Mine diesels after driving around for a bit only thing that kind of helped was turning the idle out more turns but still does it any ideas
Well don't confuse the idle mixture screw for the speed screw which controls the idle of the engine. Sounds like you need to back off the speed screw, not the idle mixture screw.
That one is set to where it is just touching the linkage
Can some one explain why my fuel hoses go in one way then out the opposite side his look like they come from the top any help
Not really understanding you. Join our facebook group and post pics and ask your questions there.
Thank you for making this video!!
Truck seems to run fine but I have some soot on my exhaust connections. I tuned it years ago and left it. Do I need to start my tuning from square one or can I start with the mixture and then idle again
You could start with the mixture and then the idle again and what it may be is that you're just letting the choke run choked too long
@@MazdaMitch since the original tune, I have also installed long tube headers of that matters.
Great job
2 thumbs up ! Thank you, Thank you, Thank you, my mom has a Mk2 Escort 1600 auto, and suddenly its just running extremely rough, I've cleaned the carb, bought new boogie cords, new spark plugs new coil, but it is running so rich, the spark plugs are black like charcoal, and the car is giving me about 7 miles /gallon. It's funny how a car can untune itself, but now I think I know exactly what my problem is.
I have an 87 Mazda b2000 could u tell me why my distributor timming has to be all the way advanced in order for it to run
You must have taken it out and put it back in and you do not have it aligned. You are a tooth off one way or the other
Mitch, loved the video…do you know anyone to take my Weber for tuning in Charleston, sc?.87 dodge Raider 4 cyl. Truck stalls when stops and then hard to start
No I dont, but it sounds to me like a fuel delivery issue. Maybe its idled too low.
Thanks for the info! Now I feel like I have some clue as to what I’m doing.
