am i right in thinking that the standard carb on the fiat 2 litre is a weber ADF? not sure of the size but 34/36 rings a bell. looking for service stuff on ebay and there is only one thing for this carb which seems odd as the engine swap was so popular back in the day that i would have thought there would be an abundance of parts for it, couldn't even find air filters for it!
so...a couple of things...
1.is it an ADF carb?? or did i just make that up?
2.are there any other webers that fit onto the standard manifold?
if i wasn't so tight i'd look at getting some fanct carbs on it as i really don't like staged carbs as they don't feel right to me!

Surely it will be marked on the carb - some form of reference ID ? The 'staged' carb should help with the economy !

yeah i had a long look at the carb, couldn't see it stamped anywhere, might be hiding under some grime somewhere though.
needless to say, fitting this engine, fuel economy was never a real issue! i don't do enough miles to really worry too much about that!

There is a Ford carb from a V6 I think that bolts straight on.

I produced a few twin SU manifolds that worked very well.

i have seen the DGAS carb, that says it is from the V6, i was looking quite a bit a that one as the two open at the same time as opposed to staged or whatever the technical term is!
SU would be fun but don't know enough the conversion! please feel free to Pm me some info on it!

stick a 38 dgas on as the 40 dgas will suck to much fuel and you would have to set the mixture so lean at tickover that it would'nt run or idle under 850 1000 rpm, but in saying this the dgas carbs can set you back a preety penny

hi again, on thinking that carb will be a 34 ADF webber and with that I think you would be better off with the DGAS weather you use the double pumper or the progresive, good luck anyway!

It's not a standard fitting but I had a Weber 32/36 DGV on until recently. That fits straight onto the standard manifold.

The DGVs were available new a few years ago (perhaps now) but aren't as good as the original which, as you say, isn't so widely available. I found the DGV was restricting power at higher revs. It kicked off nicely from standstill but ran out of puff at 4000 ish.

Although 'back in the day' it was a popular engine swap, I suspect that once someone's gone to the effort to hoik the engine in, any temprementality from the existing carb makes a good excuse to whack on the twin 45s

Have a look at motorbike carbs, they are like twin Webers in power output but work more like SU's. Having fitted a set (and before the engine bay caught fire!), they idled quite nicely even on a lumpier cam.
