that was an Emissions carb that they sold for places that needed to be emissions compliant - they never worked right and they then quit making them when they closed down the italian Weber factory. Try ebay - there are a couple of sellers on there that specialize in extinct weber models. You would be better off just changing out the 34 for the 32/36 dgev Weber - all the mounts, fuel lines, and cable hookups are the same - just one vacuum line for vacuum advance.
