[Spridgets] Thoiughts on where to plumb the vacuum guage....

[Dave G.]

While I was deciding (with the lists help) were to put the vacuum 
guage, I started to think about vacuum feed to the dizzy.

With siamese intakes and two carbs, the obvious place to put the 
guage is on the balance tube..  in that position I am truly seeing 
engine vacuum.

However, one carb could be set differently to the other, resulting in 
different vacuum readings for the front vs the rear carb...!

So why would the factory put a vacuum takeoff on the side of the 
front SU??

Wouldn't it be better to feed the dizzy from the balance tube?? 

Just curious....
