Ok, I have spent the past day reading every thread on MA that mentions dual carb Vespas in their entirety, and resisting the urge to resurrect 10 year old threads. There are quite a few. But so far, every thread has just been discussion and no evidence of any action. Lots of people wanting to do it and then nothing. Who knows, maybe I will end up the same. But, the pinasco case halves have become so cheap on treats I decided to pick one up and try this, and I'll either drill a hole in a stock crank or Benji is trying to source the mazzy special crank with the web and hole.

For the purposes of this thread let's forget about the fact that dual carbs on a vespa is pretty ridiculous and the more logical option is aftermarket cases. Previous threads already discuss in much depth the differences between one large carb and small ones, and their effects on flow characteristics.

Has anyone here on MA actually personally built and run a dual carb Vespa? I'm talking one rotary valve intake and one reed valve intake on the small half . . . but slight variations are welcome. What was your experience like? Challenges? Outcome? Was it un-tuneable and un-rideable?
