Julien -
As to the regulator: I used the same as did
splatterdog - a Holley 12-804, which was USD30 from Advance auto parts. Here is a link to Holley's International dealer page. Check the menu; there are none listed in France, but there are some in The Netherlands and Germany.

I also used a Mr. Gasket gauge, model 1561. Again, no dealers in France, but here is the link to dealers in Europe:
http://www.mr-gasket.com/DealerLookup.a ... ntryID=all. It was USD17, also from Advance - but I actually think it was superfluous.
The regulator was easy to install. Just use regular brass plumbing connections. Get them tight! Again, see the "Weberiffic" thread of
splatterdog. With it mounted on the fender, you can reverse the fuel inlet on the front of the carb (not mentioned in the instructions) to move the fuel line away from the engine - cooler and maybe a little safer?

Clarification - hopefully.
1. Clip for air cleaner...What I did for the front clips to save a little space, was to drill holes through the housing, do a bit of a countersink, and inserted long skinny bolts through the housing; not much clearance for them, but they worked. Otherwise, I'd think any place in Europe that sells Weber could supply the clips? Maybe just make them from some springy steel?
2. The line from the carb vacuum port at its base is connected to a steel tube which protrudes from where the EGR valve used to be connected to the manifold (under the heat shield). Why?
3. The vac line from the "gas filter" on the top front of the manifold leads to something on the fender, which looks like just a flat plate/piece of metal. What is it?
4. I understand you!
5. I presume your car originally had an electric choke on the OE Aisan carb? Just connect that wire to the new choke. I do not see the wire in your photos. Refer to the Weber info on T4WD's home page for photos. It needs to be hooked up to electricity from the ignition switch - I think there was info in the instructions on this.
6. Do you have vacuum connected to the distributor for advancing it? Unless - it is from what appears to be a tube running off from the EGR port at a 45 degree angle to the left? True?
7. Well - I had to drill out the holes in the adapter plate AND carb for the adapter plate's studs. PITA !
The Weber seems to be cold-blooded, compared to the Aisan - it takes a while to warm up and coughs a bit in the cold (just about 0 to -12C, so not too cold. I would think the Alps would be
much colder!).
As to the fuel consumption - and I am NO expert with jets and things - could it be that the carb was sent with jets for lowlands and not high altitudes as in the Alps? I don't know if this would be the case, but I think it could be a possiblity - maybe some of the wiser Weber-members could weigh in on this...
The word is that the Toy fuel pump puts out 7psi or so, and the Weber needs but 3.5 +/- psi, so maybe that is part of the problem as well? Maybe the regulator could help here - I do not know - I thought it was to prevent leakage from the carb due to excessive pressure, though. My gauge shows just about 2.0 - sometimes 2.5 psi, no matter where I turn the regulator's adjuster. My fuel pump was new from Advance in September of 2008, so not worn out.
I have only used two tanks of fuel so far, but am getting
about 29-30 MPG (about 12.3-12.4 km per L or 7.8L per 100km). I still have more tuning to do, so do expect somewhat more.
Hope this helps.
