Absolutely the best videos I've viewed on Weber carbs. You give gentle, human understandable information, not ego. Thank you ! I can't wait for the next video in your TVR series.
Hi, great videos by the way. I have a MK1 Ford Capri with the 3.0 Essex engine and the 38 dgas carburettor. Seeing you explanation on the anti stall I wonder if the reason for my engine stalling every time I stop at traffic lights is because of an issue with the anti stall. When the engine is at operating temperature it idles fine but every time I slow down approaching a junction or traffic lights the engine stalls. Would be very grateful if you could comment. Thanks Paul
I was one of the guys that asked for a dgas Weber tutorial. Thank you for all the details. I have a 32/36 that's 99% the same. As someone else said i knew before but now i understand!
I'll second to that. I'm having problems with a 32/36 DGAV20 that I'm not getting to run properly. Similar to this with a membrane on the 2nd port that I'm not sure how it works and what it does. It's the anti stall circuit, that was news to me. Thanks for all the useful information.
If I depress my accelerator pedal slow and the motor revs fine but when I depress it quick it bogs then what do I need to look at? Thanks for the videos!!
Great videos. Thank you. Do you have a video for tuning an installed gas 38 carburetor? I have one in my 73 FJ40 and would like to tune it up correctly. Thank you.
Hola Steve, thanks for your great detail and info. I hope see the engine runing very soon...I recomend to check the correct plane base of your carburetor. Im finding deformed it in some occasions, becase was a overtighten....good job.
I've mentioned this is your other video series on the dcoe. I used that to tune my 44 IDF for my Baja, that has a 1968cc stroker. engine. Now I'm building a 2021cc stroker for a square back I have. And I'm going with the 38/38. I am so pleased you're going through this carb as well. Thank you!!
As always, an outstanding video. There is a great educational value in leaving in your rare mistakes. It would be easy to just edit them out, but then we would not learn as much. Thanks Steve!
I am very grateful for your videos on the Weber! All around excellent, the best I have seen. I learned soo much! Thanks again! I run this on my '76 Toyota FJ40.
Great video & instructions. 1 question> To me it looks like the anti stall membrane cover needs to be rotated 180 deg as there is a port sticking out on the flange below the vacuum attachment tube ( which can be seen at 11:44) which corresponds to a port in the carb body ( which can be seen at 22:09 to the right of the membrane flange , below the idle jet holder hole) ??
Awesome video. I've been playing with carbs of one form or another for over 30 years and know my way around them fairly well but i never had as good an understanding as what i do now of the emulsion circuit and its relativity to the float level. Thankyou.
Man, i've just installed my weber 38/38 (spaniard one) on a nissan e16 engine... runs great on idle, and cruising... but when i hit the gas to the floor it bogs quite a while and then it starts to come up gradually, until up in the revs where it's running lean... have checked for vacuum leaks, float level, ignition and everything seems good... it works ok if I pressed the gas to the floor kind of slowly (no bog there) but above 4000 it's lean again... ¿do you suggest that I increase main jet size?? Thank in advance. Greetings from México
Absolutly the best video on a carb i have ever seen i take my Hat off to you sir you are a genious very nicely explaind . By the way you remind me of Alpachino.👍👍👍
I see there’s a retro throttle body EFI conversion kit available for the Weber DGSA 38 from a company their in the UK 🇬🇧, outside of cost what is your thoughts 💭? I have had friends here in the US 🇺🇸 who have used EFI conversions and say they will never go back to a manual carburetor.
indeed they exist and work well. you will need additional sensors, and that is where most issues are. imo, a well tuned carb is as good, but yes those units perform well
Learnt such a lot - again! It makes it so much easier to do these jobs if you understand the function and operation of the parts, something that manuals do not (and they would be like encyclopedias if they did!) tell you. So thanks and looking forward to the next video.
Super nice video again! It's so easy to understand every bit of this as you speak about the different parts. I almost bought a Haynes manual on Weber carburetors because of your vids (I don't have any vehicle with weber carbs... :D ), but they are so interesting, full with these precise mechanical control systems. I'm not really into car carbs, but don't you need some type of thread locker or something on the butterfly screws? I would be scared that they unscrew from vibrations and fall into the intake.
Very instructive and detailed videos! I have a Spanish made Weber on a 4.0 engine that stalls on Steep inclines, setting up the float level parallel to the top cover helped a lot. However it does not have the anti stall circuit, would that help on steep inclines?
Excellent. Filled in a lot of blanks in knowledge. I new what the accelerator pump did, but not how it did it. The same could be said for several other functions on the carb. Thanks for the excellent presentation.
Great video, love the white board explanation, best I’ve seen on explaining the individual circuits, and how they each interact in conjunction with others… great job!
Hello Steve - I thoroughly enjoyed your video. I have a question for you: Once I reach 100kmh, my TVR Taimar starts to stutter. It runs fine up to the point. I cleaned out the carb the other month, after it had sat for a while and didn't have any issue at higher speeds. What are your thoughts?
great informative explanatory video thanks. One question though - when adjusting the float level, if this has already been done there is a possibility that the metal bits are slightly bent out of shape. When adjusting Dellorto DHLA carbs someone has given a measurement of 27mm from a point A to the surface of the fuel. Is there a similar depth measurement of fuel in the chamber of the 38 DGAS? the procedure is very time consuming i.e. adjust the float, fill the carb via the pump, take the float chamber cover off, measure the depth (in the Dellorto case 27mm from the top of the jet holder base) adjust the float if not right and repeat (again and again sometimes). I'd love to know where the fuel level needs to come to relative to the main emulsion tubes in order to fine tune the running mixture.
Sir! You are truly the PHD of Weber carburetors! I have a question for you if you have the time? I have a beautiful Volvo P1800es I have converted to Weber 38/38 dges. The Weber is Chinese and not from Spain! I was fooled on this purchase. About 1000 miles on b20 engine. I have played with this carb for a couple of years now and still get hesitation in mid range RPM, otherwise runs pretty well. I have .47 idle jets at this time. I tried .55,.50,.45. Now my mixture screw is 3/4 turn out. Runs great, but still hesitates on hard acceleration? I live at 5000 foot elevation in the mountains of Arizona. Any ideas? I am going to run your videos again and disassemble it piece by piece. Are Italian Weber’s used in other countries? I travel to Colombia SA ? Do they use them there? Once again professor, Thank you very much😎
Sorry for the late reply , as i was away for work. But thanks for the comments. The Spanish and Chinese Webers are both of poor quality, try to stay clear from them and rebuild the old Italian version. Acceleration is aided by the acceleration pomp, I suspect that you have a membrane failure, that is why its a good idea to rebuild the unit entirely. There are kids available to do so
Excellent video and I've just gone over mine again to double check a few things...noticed you might have missed a seal washer off the top of your accelerator y jet...I'm sure its a banjo type i e one washer top and bottom. Also top tip I'd like to pass on....lip balm on the gaskets stops them sticking especially when in and out a lot. ..old hot rod tip. I have a few sets of carbs for my rs2000 and the 38dgas ran the best, currently I've got a side drought 45 on a lynx manifold that's running nice...I do have a set of IDF44 which I've overhauled but just can't get them signing 100% again even using air sync and measuring the progression setpoints on the butterflies... Be great if you could do a video on their specifics ,Excellent knowledge and great for all levels.👍👍👍
hi Steve, i like the way you explain complex thing. and i haerd that you are electronic engineer. dont you have another channel where you give electronics basics. i like that you dont just do things. you do them in such a way that a blank someone will start to have a clue moshitoa (south africa) ds3 shooter follower
I've tackled with the 32/34 model from Ford Sierra quite a bit, this one is pretty similar and for me it was a very interesting two part series. Definitely learned some things I didn't know. Thanks a lot, now on to the tuning video
Amazing video Sir . I am from India and I bought a brand new spanish weber 38 DGEV for a G13BA 1.3 litre engine . I have already run into issues and your videos have been very very informative. I shall try to fix the issues myself ..
Absolutely the best videos I've viewed on Weber carbs. You give gentle, human understandable information, not ego. Thank you ! I can't wait for the next video in your TVR series.

Hi, what measurement for a plastic float Spanish 38?

I think I do have one in the playlist on the TVR or the weber
hey,
i installed the carburettor exactly you describe it. But in the idle the aceleration pump valve drops gas out. what could be wrong with it?
Could be many things, float level, needle valve not closing, to high fuel pressure from the feul pomp .
Just re-measured float tolerance and it was 40mm and 46mm? I reset to 40mm and 50mm and can’t wait to drive😎
hope you have a great drive
Do you have a video of how to add the anti stall circuit to a carburetor that doesn't have it
I don't....but maybe I make one...
Hola Steve, thanks for your great detail and info. I hope see the engine runing very soon...I recomend to check the correct plane base of your carburetor. Im finding deformed it in some occasions, becase was a overtighten....good job.
thank you for the comments, indeed that is sometimes an issue
Awesome series; this carburetor is as good as new. The TVR project is coming along great!
thank you for the comments
This is by far the best and most informative video on the Weber DGAS carb that I have found. Thank you very much.
Glad it was helpful!

happy to hear so
What great fun😎Are the Italian Webers available sir?
hard to get, only second hand
Typo in the video title my friend DGAS not DGSA
hahaha , than you

Very informative Steve, I learnt quite a lot I did not know about the Twin Weber carburettor. Thanks Steve, looking forward to the engine tune now.
thanks for the comments
Will this work same float adjustment settings for weber 32/36 with electric choke and brass float?
Absolutly the best video on a carb i have ever seen i take my Hat off to you sir you are a genious very nicely explaind . By the way you remind me of Alpachino.👍👍👍
I had other people telling me that ... funny Alapchino, in fact its even a favourite actor if mine
@@D3Sshooter hahaha.you look and sound exactly like alpachino.
My favouret actor.👍👍👍
I really enjoy these thorough and detailed videos
thank you for the comments
lets talk about electrical choke wiring install on this carb please,...thank you
how do you rebuild the choke mechanism?...I'm stuck

Thanks for the comments, and yes you ether lock those small screws with a locking product or punch them open in the back( if brass)

Thank you for this video series. I learned everything i needed to know about my 38 dgas on my Toyota pickup.
Excellent. Filled in a lot of blanks in knowledge. I new what the accelerator pump did, but not how it did it. The same could be said for several other functions on the carb. Thanks for the excellent presentation.

Thank you Steve, brilliant Video.
thank you for the comments
Great video, most of youtube content is about performance. I like learning about how it actually works.
Great to hear!
Great video...very, very well explained..
Brilliant explanation, thank you
Super great video as usual! So educational and easy to follow. Really good with both theory and the practical part.
Thanks again!
Big thanks to you Steve 👍. Nice video n information. Enjoyable
thanks for the comments
What is the jet size for a ld28 engine
It was a great help, to rebuild a weber
these diagrams have helped me understand this better than any manuals I have read. Thank you.
Thanks for the comments
Beautiful, thank you!
Great video, love the white board explanation, best I’ve seen on explaining the individual circuits, and how they each interact in conjunction with others… great job!

This is great! I run a Weber 38 on my 1981 DeLorean, paired with a Renault R-30 intake manifold...Webers are new to me, so very helpful indeed!
Thanks for such a clear demonstration. I have found this series of videos a huge help while rebuilding the DGAS 38 fitted to my Reliant Scimitar SE5A.
