to further clarify in case this was inadequate... 32/36 Weber DFEV carburetor, which is an electric choke carburetor only used on Fiats aftermarket. Coupled with an 1800 intake manifold, this becomes a HUGE performance increase for the sickly, over emission controlled '79-80 carb'd spiders. not legal in all states, yada..yada.. as the carburetor has zero connections for emissions equipment.
not trying to insult the original poster, but this looks like it is a 2 litre engine, due to the fact that he swapped in a F.I. dispstick tube. if it were an 1800 engine, that modification would not have been needed.
as an update, i have installed a 12mm carb spacer provided by IAP since my last post. previously i had run for two full seasons with the carb bolted directly to the intake manifold. i have found zero difference in performance, having not experienced any issues without a spacer.
Terry - - are you referring to the 1800 intake manifold with the pipe off the front of the manifold? that sucker can be on real tight! Try a modest amount of heat with a propane torch (of course remove any fuel source, or take the intake off the car). as i recall, that pipe removal takes a hex key or allen wrench. there is a secondary fastener inside, might be hard to see while on the car.
