1958 FE intake utilizing 4100 carburetor, vacuum leak at base

[Gene F]

Can't ya get a Holley 4-barrel gasket, and lay it over it, and cut it with an exacto knife? (Not a utility knife)

The 58 intake manifold casting for the carb base mounting surface does not extend out to the perimeter of the carb base at this corner either. So there is a triangular-shaped vacuum leak about the size of a pencil diameter in area. Sounds like a vacuum cleaner when running, unless plugged with a fingertip.

You put your finger where exactly? There is a machine screw hole at that point made to hold the dash-pot assy on. Is that hole threaded all the way through the base plate?
