Weber Marine Carb on 360 la engine?

The simple questions.....
How much idle vacuum do you have?
Possible vacuum leaks?
Is the port/circuit plugged/blocked?

Aside from that, some tuning instruction here............

That should be a sticky in the Carb forum ! How is it I have never seen it before ? The current Edelbrock instructions are so vague !
