Weber Marine Carb on 360 la engine?
Okay so I've taken it off and apparently both of the ports for the primaries are above the plates.
I did see light through the driver's side passage so it isn't blocked.
You can see the line where the plates are closed is above the ports.
And this last pic above is with them closed...
So I guess if I want manifold vac from the carb it will have to be off of the choke port?
It has the choke installed but I've never had it wired so it's always been capped.
