Carb balancing

It's ALIVE !!!
Got my rebuild engine running, now that the car is somewhat mobile I should be able to move her outside and take some pictures, which I will post.
Anyway, wondering if anyone can recomend a method of sycronizing the two carburetors? The steps in the Hudson manual seem kinda lame.
I've never done multi carbs other than motorcycle engines, in those cases I used a mercury manomiter attached to a vacum port at the carbs. My carbs don't have a port.

Cheers Dave

Yes you need to use a version of the balancer that sits on the throat of the carb. Its called a Uni-Syn. Pic below.

You use this tool. Its not perfect but it gets the job done. I much prefer using a manometer which I also use on motorcycle carbs. I do not like putting something over the throat of the carb as its counter intuitive to interrupt the air flow but I have the tool and it works well enough.
