SVDA Dizzy; Where Do I Connect The Vac Hose?

you have it connected correctly now, don't change it.

Yeah, you're fine. The vacuum port on the intake manifold was used stock to actuate the warm air valve for cold startups, then the thermostat in that valve would slowly close it as the engine warmed up.

The vacuum hose from the SVDA is connected to the vacuum port right beside the mixture and idle bypass screws. From your perspective, it should face left and it's quite high in the carb body. 34PICT3 carbs may have two other vacuum ports facing you at the base of the carb. Don't use these for the distributor.

It's also normal not to have any vacuum at this distributor port at idle or at full throttle. It's only when the throttle plate is slightly open, and the brass plate is above the tiny hole that eventually leads to the port does a signal get passed to the SVDA.
