There are two ways to check if its the 9.35:1 compression, 93 aki, 138 bhp, 225 lb-ft version of the Cross flow 4.1. One is via crank stroke, drop wire down number one, and raise and lower the first piston and mark with a marker the top and bottom movements, and then measure off. If its 3.126 inches or near offer, its 200, if its 3.91, its 250. The second is that the distributor unit has a code number on it for calibration, which allows you to find the engine.
Only DGAV, DGAS and DCOE parts are serviced for Webers. That's because there has been a raft of orginal Spanish, Italian versions being replaced by Weber branded South American or Far Eastern copies.The better, orginal Weber ADM 34 parts are supplied from other agents. The ADM 34 comes with the easily adjustable electric choke and idle solenoid to stop engine run-on. The stock 32/36 DGAV and 38 DGAS only have these as extra cost options, and then you have to rejet and recalibrate them. Problem is, the supply is being overtaken by the non OEM Webers, the US market, Interco/Weber Carbs Direct workalike carbs like the EMPI carbs built in China, the EPC 32/36e, EPC 32/36m, EPC 32/36a, EPC 38/38e,EPC 32/36f and EPC 34. These look just like other older Webers, but are not. So the aftermarket has raced to provide for these, and not the more developed ADM 34.
When the engine is cold, the auto choke spring contracts, closing the choke. When the engine is running, the spring is heated by a 7 volt electric current, taken directly from a terminal on the vehicle's alternator. 7 volts is te requirement, but 12 v is what some people use.
On some cars, the idle stop solenoid is connected to ignition power so that the throttle is held open while the engine is running then closes fully when the key is off to prevent dieseling. If that is how yours is wired, it will work for the electric choke. On other cars the solenoid is normally retracted and is only powered under high load conditions, such as when the A/C compressor is on. In that case, it will not be suitable for use on the choke.
In America, the Weber parts suppliers are very, very good. The problem is you Americans have a population base far more than just 23 million people, and the Australian suppliers are geared around local supply, they don't really think international.The exception is Recarb
The 34 ADM carb is listed with similar parts as the 34 ADFA used in twin cam Fiats. Standard parts supply ex Australia is pretty good via GEM Parts Australia , but the supplier, while very competitive, is fairly mercenanry, with the occassional bad feedback. As a percentage of sales, Matts feedback is okay. Other suppliers can only match the cost on a full carb rebuild.

I'd suggest you try Matt and see how you go.
The best supplier, if you are prepared to call them and talk about your needs,
is ReCarb

Problem is they only sell whole remanufactured Weber ADM34 carb packages for five generic engine packages, and don't service Falcon X flow XE/XF engines at all, since most guys get least cost parts from Ford Australia New Old Stock or GEM Parts

Like everyone else, its other newer conversions usually use the more expensive 32/36 Weber DGAV and 38mm DGAS. Ford Australia, via Borg Warner/BTR Australia, had supplied about 650000 Weber ADM 34 equiped 3.3 and 4.1 cars from 1982 to 1992, with parts supply still around from Ford Australia. Since Ford Oz still has big garage sales, any supplier for ADM 34 parts has to compete with new old stock Ford Australia parts from 82 to 87 Ford Falcon sedan and 1982-1992 Falcon pickups, the 1988-1992 Nissan Ute and 1982-1985 Aussie F100 pickups with the 4.1 engine .
To make it work, you have to have four bases covered
1.idle stop solenoid needs 12 volts through it to work.
2.The electric choke needs 7 volts to work, but will operate on 12 v. The carb is found under
http://holdenpaedia.oldholden.com/Weber_Conversion
3. The fuel pressure is regulated by a bleed back corrector valve, that uses a specific 1982 to 1992 Alloy Head II XE/XF Australian Ford Carter fuel pump, bassically the 1983 to 1985 5.0 4-BBL 4180C Holley fuel pump with bleed back and vapour return line. You have to use 5.0 GT logic to make sure it doesn't flood. A Holley fuel regulator with no bleed back might work, but its easier to just run a return line.
4. Float level needs to be in spec
The carb replacement hardware is listed with similar parts to the 1974 onwards European and Australian Mopars and European Fiats
ex 1. Talbot Solara, Chrysler 2 liter, Chrysler Centura, Chrysler C160/C180/C200 listed as 34 ADSDA 11 and 34 ADSDA 15 as a 22/26 venturi carb
and
2. 131/132 Fiat, where its listed as a 34ADFA on the 2 litre 131, it has venturies of 22/24, 23/25, 24/26.
