Re: fuel condensate drain on the carb

This is based on my experience with the 356 engines and may not be the same thing. The condensation drain on the 356 is connected to the rear of the intake manifold [not the carburetor] and allows excess fuel in the manifold to drain off. The drain is closed by means of a ball bearing that is pulled up by vacuum when the engine is running.



An earlier discussion on "Anti puddle valves" can be seen here.

I have a 356 with and a 356 without and generally I don't think the valve makes any difference in engine performance.
