What is the gasket set up for the Weber starting from the intake to the base of the carb. I think i've got a bad vaccum leak between the heat shield and intake or heat shield and carb. What gaskets do i need in what order? The PO didn't have the carb tight, just sitting on the intake.

Baz, I used that on my hose setup, but i have not found anywhere the placement of the gaskets and spacers for the mounting of the carb to intake. Really, i've looked. Maybe i just have not used the right search word combo yet.

Gasket stack ...

Manifold - paper gasket - heat shield - paper gasket - insulating spacer - paper gasket - carb.
That is why the studs are so long!

Thanks here is a picture of the carb with questionable hoses. There is no charcoal canister in the car. I think the PO tried to route around it. Hoses don't fit where the diagram in earlier post say they should go.

Here's a pic of the carb. The label saying 2 lines going to distributor are the 2 lines going to front and back of vaccum advance. So there are 3 vaccum lines here, brake booster vaccum advance and retard. This doesn't seem right to me.

Thumbs up Manifold-to-carb stacking order

If you follow that stack-up, you won't have any fuel bowl percolation problems . . . even if driving in Texas summer heat!

Yes

Yes, the Weber 32/36 DGV 5-series, 5-A series, and 33-B series
(as well as the 32/36 DGEV and 32/36 DGAV) will bolt up to a
1.9 Manta manifold (although you'll need to adapt the throttle
linkage and air filter).

Additional instructions are here:

I don't know where to post my questions but this looked like a good spot.
How much milling of the choke housing before ventura booster problems? (32-36 DGxV)
I need air and lots of it under the confines of the GT hood.
Also is the 32-36 choke housing interchangeable with the 38 DGxV?

If you want a carb that you can just put on and not worry about jetting and all that fun stuff, you need to go to OGTS. I got my from them and it works GREAT! Very great quality. I think I paid 383 for the carb all the linkage things gaskets and the chrome air filter. WORTH EVERY PENNY!

the answer is YES for the choke question. With regards to milling, you dont want to mill that housing. that gives more air into the carb
