What's your elevation?
Found another forum, Iszuzu Trooper also a 2.3 like my F head, general consensus is 60 idles, 179 air correctors, 140 mains. Testing that today.
I'm at 560ft so basically sea level but North Alabama for humid but cooler now it's fall.

Interesting jetting on mains, though I have a Weber 38 per Redline and others recommendation for my bored, decked, Isky 242/238 camshaft grind, free flow exhaust 61' CJ5 F Head. I can get the idles and mid great, but WOT is either too rich or too lean.
Interesting to see you have 175 on the primary and 170 on secondary.

Considering turning my 38 into a progressive as I have a good 32/36 to pilfer parts from, it's been done, a South African did a YouTube video on it, a few have performed the mod with success.

I just need to get it optimized before attempting. Did your 32/36 come from Redline, and if so, was it jetted as you stated or that's what you have landed on?

He was very nice to burn me one.  There is an off the shelf adapter out there that if found after the fact.  I think that adapter was $40.  Let me see if I can find it again.

I'm looking for that magical webber 2V to L-134 in my M38... You mentioned that you have a CAD of an adapter you used, how much would your friend want?

Cheers, Lyle

I wrote a whole post on how to clock a Weber and why not having it clocked properly with the bores 90 degrees to the Intake manifold runner will cause not only problems but imbalance.

The positives are both runners are the same distance from the Primary and Secondary barrels, The Float works better on inclines or declines (though it could be better) the Fuel inlet points right at the Left fender. Choke cable lines up better.

The two draw backs are the adapter or manifold is a little harder to make and of course you need to put a 90 degree bellcrank in the throttle linkage.

I have so far seen to guys kindly offer up their tuning numbers on the DGV 32/36 on the 134L and they vary a little (could be altitude or even what kind of mixture numbers are being sought)

I know what these carbs can do when properly adjusted My Wifes 67 Mustang with the 200 L6 was amazing. (it was actually a Holley Weber 5200 but basically the same carb slightly smaller CFM rating)

I'm familiar with Rango and Brennan's tweaks which is why the 2100 is being considered but the 2100 is synchronous where as the 32/36 is progressive which has it's perks.

Look up Brennan's Garage on FaceBook. Brennan Metcalf has invented a mod for Motorcraft 2100 to improve it's performance in steep angle and off camber situations. 
That's what he runs on his super modified MB Rango.

My son has this Weber on 4.2L in CJ-7.    It does well offroad in fairly steep angles.    The carb is rotated 90 degs from photo shown above, however.   ie. the float bowl is pointing to front of engine.   I think I read somewhere that make quite a bit of difference.

Interesting modification on the Choke bowl vent. I'll have to think about doing that to my carb.

Ok, I'm in the process of doing the 6-12 months of research before I upgrade my carb to either a Weber 32/36 or a very small Motorcraft 2100.  The dual stage of the Weber is attractive as is the tune-ability. The toyota guys figured out how to make the Weber carbs run better off-camber so I'm not as worried about that.

The FI option is attractive but I bought a Willys for the rugged simplicity so I'm trying to keep it that way.

I never actually made the engine swap.  The fully rebuilt zero mile Dauntless, T15 with adapter, and late model T18 are all sitting nicely in my barn next to Sparky.  Perhaps next year...I have been saying that for quite some time.

IIRC you've since swapped to a v6 but what were your long term experiences with this carb?

Rocketeer I believe what 52 MB38 is saying is that the total of his external engine improvements has resulted in a 20% improvement.
 
I took a fresh rebuilt Ford 200 6L in my wifes 1967 Mustang and with the following external changes went from a car that Road and Track in 1967 got 19.5 MPG and got an average of 26MPG commuting 85 miles a day on two lane country roads and some in town miles.
 
Petronix magnetic trigger in newer 1968 distributor that allowed adjustable mechanical and vacuum advance.
MSD 6A spark box
Accel Hi performance coil and Accel suppersion high performance ignition wires
Electric Fan
Electric Fuel pump w/Pressure regulator
Holley Weber 5200 progressive 2bbl 270 CFM on a 3/4" thick adapter I made my self from Aluminum
Phenolic spacer (helps keep the carb cool)
Fresh air intake using 2.5" vacuum cleaner hose an aluminum sauce pan a 2" ABS pipe elbow and a K&N cone type airfilter places just on the outside of the core support just under the lip of the hood
Clifford research 3/4 exhaust port splitter
Cilfford Research 6 into 1 header flowing into a mandrel bent 2.25" exhaust passing through a 2.5" inlet/outlet Turbo muffler with a short 2.5" tail pipe
 
1977 RUG 4 spd with a 18% OD in 4th
 
The car had way more power in the bottom end and would cruise along at 100 to 110 mph like it wanted more. (Hwy 139 in CA. we did it for almost 45 min)
 
We ran the car like this for well over 120K before selling it to a college girl.
 
All the little things can add up.

I am very happy with this set-up.  The power difference of the incremental changes has been impressive.  I have stuck to my original plan of only bolt-on mods.

if you have an intake that allows the double barrel to flow directly into the intake you are able to increase power to about 20-25%. 

With a stock duration cam on an L-134? I don't think so. I built a lot of race cars and did a lot of racing. If a simple carb and manifold swap could boost power by 20-25% it would have set the hot rod world on fire. With a longer duration cam, a true high compression racing head, polished ports, custom tuned intake manifold, and a much beefed up ignition system you might come close to 25% on a small 4 banger flathead.

There are a couple of options for mounting the Weber:  1.  You can make your own intake, which I plan to do next year.  2.  Have an adapter built specifically for you.  This is what I did.  One of the members on here had a cad template and a friend of mine owns a CNC business.  3.  Spend some time and find one of the commercially available adapters, they are out there.  4.  Use a Kaiser intake or maybe a Willys truck intake that has the wider spread studs and use the terrible adapter that Weber provides.  If you do some reading on the subject of going from a double and throating it down to a single point you will only see about a 10-15% power gain, if you have an intake that allows the double barrel to flow directly into the intake you are able to increase power to about 20-25%.  I really like the set-up I have, but the tinkering is what I love to do, the incremental improvements.  In the second photo you can just barely see the lettering on my Supersonic head.  For those who are worried the plastic white zip ties are NOS.  There is a snorkel cap for the Weber that will transition it over to the cross over pipe, but that is a plan for years to come.
