Thank you very much; very informative. If someone reading this knows where I can view a video dealing specifically with the “32BI” model I would be most appreciative,
You mean how it gets from the float to the various ports/circuits mentioned? There are internal channels/drilling that allow the flow of fuel and the "jets" meter the air and fuel respectively to ensure the ideal air to fuel ratio. If you are asking about how the fuel gets sucked from different "paths" then that depends on the amount of vaccune that the throttle valve exposes to these "paths". To understand the theory, you can read about Venturi effect
