That is what the literature says, but I wonder how much torquey the engine would get with the DGAS. I will keep looking, I would like to know if the extra gas consumption is justify, or perhaps the DGEV 32/36 would sufice. The advantage of the DGAS as told is that it would be able to use the aftermarket manifold, whereas the 32/36 would not be able to use the manifold to its potential, I assume lower vaccumm in the 32/36 set up vrs the 38 DGAS. I do not know the DGAS, never driven a car with it.

One of the vendors says the 38/38 should be better for torque than the 32/36, but the latter is better for driveability and fuel economy. They were talking about the 4.2 liter jeep engine. See the Tech Section article Which Carburetor?

Hy Dim, would you recomend a 38 syn against a 32/36?, I have a new 32/36 I'm about to use in my jeep, but the 38 syn is a posibility, and I can exchange it now, while my 32/36 is still new. The 38 DGAS would allow me to use a special better flow manifold, while the 32/36 would use the stock manifold. (I've been told the 32'36 would not have what it takes to use the better manifold.), the downside of using the 38 might be the gas consumption, is there a huge diference , or is it not that big of a diff,I know there would be a difference , but never used a 38DGAS, and although I am willing to forgo some gas mileage, I use my jeep for trips, so, some is oK, but I do not want a V8 gas drunk guzzler. I know this is not datsun talk, it is my other vehicle, but still weber 32'36 talk.

The 38/38 DGAS (synchronous throttle plates) that I ran in my built NAPS-Z 2 liter did have a slight amount of rich smoke and sooty deposits in the tailpipe. However, when I jetted it down (it was originally set up for a 4 liter Jeep straight 6) it ran like poo and wouldn't idle until fully warm. Tensandtwenties has that same carb, with the original jetting, on his 510 (1600) with an L-20b. It smokes pretty good on that engine!
But then again, I'm comparing apples to... well, much bigger apples! To answer your question, Unfamilia, I have not really noticed a rich smoke problem with a 32/36 when I run the jets the way it comes.

As for the parts counter guy, he's been selling Weber stuff for quite a while. But I did say he might be full of it! It is probably a case of what all of you have said, they WILL run with the factory jetting, but it IS a compromise. He's also a V8 man, they might be more forgiving of a mis-jetted carb.

That parts counter guy is like 90% of guys working in parts places, perhaps his previous job was as a waiter or delivery guy, they do not really know what they are saying. My DGEV 32'36 Weber came jetted for an A15 Datsun,and I remember changing the jets for a smog test , I bought , after it did not pass the test,the right jets recomended by the weber dealer (Pierce Manifolds) and then it did pass, and I could tell the difference in performance. Once passed, I went back to the larger size primaries. Any carb will start, but the performance will be just oK, not optimum.

The parts guy is typical.

But in a sense, yeah it'll start and run, probably fairly well. Even if it doesn't put out black smoke, the mileage AND power can pick up with the right jets.

A-14, I suggest getting from your library a book on tuning Webers. It'll cover all the basics and all the details too. The Which Carb? article also has links to some general tuning pages, but more interesting some info on A/F meters.

just curious then dimlight, does it belch that running rich smoke when you accelerate heavily or lift off the throttle?

I had a parts counter guy, just this last weekend, tell me that all Webers are jetted the same from the factory and will work from 1100cc up to 2000cc and all that needs to be set is the idle mixture. I think he may be full of it! But then again, I have never messed with the jetting on one and they have always seemed to run fine. Of course you must remember, I'm very VERY lazy and if it fires up and drives, I'm happy.

Anyone got any tips for me on jetting and installing a 32/36 on a a-14 motor
