Weber Marine Carb on 360 la engine?

I have a Weber (9635sa 3026) on my 360 with an Edelbrock performer 318/360 manifold and I am not getting any vacuum at idle from what is supposed to be the manifold vac port
(drivers side).
I recently rebuilt the carb and it runs a lot better than it did but still has an inconsistent idle.
I do get vacuum from the port under the electric choke at idle.
This is my first project car and I have some pretty gapped knowledge as I just learn as things go bad.
Any info would be extremely appreciated.
