[Spridgets] Early Smog Carbs

[David Lieb]

Brad,
1) Ported vacuum would have been on the front carb on a Spridget.
Barbed pipe pointing horizontally frontwards near the top of the mounting 
flange.

2) The overflow was "intended" for fumes, not liquid. If you have a charcoal
cannister, there would have been a pipe and some hoses to connect these to
the cannister. Their purpose was to cease venting gasoline fumes to the
atmosphere. Earlier carbs has a vent hole with an aluminium cover over it to
keep debris out.
