    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'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!!

      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.

    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 let me know how you get on with the mod.

      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.

    What a genius little idea. Glad to see you've done it. Any vids of this running on a motor or some results?

    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?

    • @carburettorrebuildservice8964
      @carburettorrebuildservice8964  6 месяцев назад

      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 .

      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.
