I've got a really hot 1.6 in a Samurai. I've been running it on a 38/38 but it's really lazy down low. I just slapped a spare 32/36 on it and it really added a bunch of nut down low but now she's out of poop at 5500rpm. I've long had the thought that a DGS with a progressive linkage would be the best of both worlds. I'm happy I'm not the only one to have had the thought.
the reason you lost power down below is because the 32/36 has smaller venturies (26/27) and is progressive (probably also jetting), the two 38 butterflies that open together has a large effect on lowdown air flow, i hope it makes sence
Funny, I've been playing with and flow testing a 32/36, different mods like polishing Venturis, shaving posts on Aux Venturis, air stacks, etc. Juat for fun. I have a 38/38 on my Jeep 258, and the other day wondered what would happen if I made it a progressive like the smaller 32/36. Seems it would be the best of both worlds. Glad you did this, thanks!! VERY Interesting!!
Very interested in doing this mod to my 38 DGAS for my 61' Jeep CJ5. I think this would be very beneficial for off road and on road. I do 70% on road, 30% off road as it's my daily driver. I was talked out of the 32/36 simply because my engine is mildly upgraded with slightly higher compression, larger bore, mild 240/238 camshaft grind and 2" free flow exhaust, so it moves more air than a stock engine. Your modification looks to be the best of both worlds for my application. Sadly, as it is my daily driver, and I am located in the US, I will have to perform this modification on my own due to logistics. I did source a genuine Weber 32/36 to cannibalize the parts from.
Please remember to turn the idle mixture screw on the 2nd choke in all the way otherwise it will struggle to idle. you probable need to use a larger idle jet on the 1st choke. thanks for watching my channel.
I always wondered, if your carb is an appropriate size for your engine- why are there differences in fuel economy between say a 32/36 and a 38 DGAS? If you drive normally, shouldnt the carb only give the engine what it is asking for and that determines the economy?
hi, thanks for watching my videos, it all depends on the setup, in other words, the main jets, air correction jets, emulsion tubes, auxiliary venturies and the float level. you can have the correct size carb on a engine and be using load of fuel because the main jets are to large.
I'm in the USA. I had this idea years ago but could not get anyone here to help. can you make a conversion kit available. I have a 2.2 l mopar fwd with blower but runs very rich just off idle to maintain speed .
Hi i have a microbus 2.5 running on a golf carb .. i just bought a second hand weber 38 dgas.. its looks complete but needs some cleaning... Problem is how cn i get it on a 5 cylinder audi manifold.. because i cant find a stand anywhere..
Ooh! I'll have to check that out. I've been meaning to so the same mod for a few of the old engines I'm about to put back together here. @@carburettorrebuildservice8964
This answers the questions I had on one of your other videos… brilliant innovation!

It works great thanks to your video I turned my 38/38 to progressive and I solved my problem with so much gas, thanks.
I am glad it helped you, my 38 is on my 1400 pick-up and it works very well.

Yes it works a treat and you now jet the two barrels differently, 1st barrel for economy and the 2nd barrel to add a little performance.

Please let me know how you get on with the mod.

Hi, i will look into conversion kits, i have has several requests for it. thanks for watching my video's.
Hi i have a microbus 2.5 running on a golf carb .. i just bought a second hand weber 38 dgas.. its looks complete but needs some cleaning... Problem is how cn i get it on a 5 cylinder audi manifold.. because i cant find a stand anywhere..
please whatsapp me on 0606546966, perhaps we can have an adapter made.
What a genius little idea. Glad to see you've done it. Any vids of this running on a motor or some results?
Yes i do have some videos running it on my Nissan 1400
Ooh! I'll have to check that out. I've been meaning to so the same mod for a few of the old engines I'm about to put back together here. @@carburettorrebuildservice8964
Good evening everyone, kindly note share details where I can send my 38DCD for converting to progressive, I'm based in Durban
Hi, you can contact me on 060 654 6966, whatsapp please
can I send you mine from USA, my only concern is will this work on a supercharged engine,
Is it a big difference in power i started with it a few months back and never finished it is it better
Yes it makes a big difference, it revs up like you cannot believe, i love this mod on the 38, it makes it driveable for small engines.
@@carburettorrebuildservice8964 then i wil finish mine what jetting did u use
