They look pretty simple and I was thinking about them as a carbed 2.8 canidate.

They were used a lot in the late 60s and 70s

not sure - but I helped my dad tune his two banks of tripple webber carbs on his porsche 3 liter flat 6 after he put it into his 914

I bought a book on the subject because I had the same thoughts. One thing I found out is you REALLY have to know how to tune them. They rely on engine vacuum to operate correctly. Once you get them "dialed" in they are good to go.

would you be willing to let me borrow it if i pay for shipping?
or are the "important" pages scanable?

For what it's worth, I heard that Weber recently closed its doors for good.

Buddy there's 3 or 4 fairly inexpensive books on Webers on these sites.

Do a search for Weber carburetors.

"Let a man drive a Fiero and he'll own one.
Teach a man to fix a Fiero and he'll own eight."

Engine masters magazine (winter 2004 edition) had a great article on EFI in carbs clothing. There's a company called mooneyes that makes some replica stromberg carbs. However they are actually throttle bodies. Perhaps they can help you out (that's if you wanted to go efi).

I also had dual 3 throat carbs on my Porsche 911 engine. They were a real PITA to adjust. They do make a gauge that goes in the venturi to help you syncronize them. I had to constantly fool around with them. Remanufactured ones cost arount $1200 and far as I could find, only one place does them in the country. They do look impressive though. A friend has 8 (4 dual throat)on his 289 Ford GT40 (OEM in it) and he spent a lot of time getting his to run right.

They are similar to Mikuni's either side or down draught you need the synchronizer which is like a ball to stop the ram pipes and adjust each of them individually to the same level in the sequence of the firing order once you are finished adjusting them you can use nail polish to lock ther screws from backing out .

i have a 4 tube sync gage that i use on bikes.

but i was wanting tuning tips and pitfalls to watchout for.

other than being a pain to tune they work really well

oh and make sure you clean any burs out of the jet orifaces before use or it'll run like crap

I was going to use Webers on my 124 spider, but they were too costly, I went with 4 Mikunis from GSR on my own manifold instead. While they look neat, some day I'm going to change the whole setup over from an Electromotive Tec I to Tec II or III and go with Fuel injection. FI is so much easier to work (just burn a new chip) with and is simply the beter setup.

I had webers (2) on my Fiat 124 back in "72 - the car was a '69.
I never had to touch em. I heard they were a PITA to work on (like the rest of the car) but I was lucky, I guess.
IMO, Mikunis would be a better choice. More people are familiar with them and they are pretty easy to play with.
HMMMMM, A fiero V6 with 6 downdraft singles or 3 - 2 bbls would look like a vintage Ferrarri, If you could cobble a linkage and get the jetting right. Very cool.
