Connecting vacuum gauges to each other?

I use just one gauge for a twin cylinder.
I used a Y connector to join both carbs to one gauge.
I then pinch off one hose with a clamp so I'm only seeing the other carb's vacuum signal.
I then switch the hose clamp to see the other carb's signal.
I adjust the carb sync screw till they are the same.
It's easier with multiple gauges but i'm cheap.

Well, kinda cheap--I use a single pressure transducer and an oscilloscope now.
Which makes it harder to read as you see the reversion signal as well.



With 4 carbs you would use 3 clamps.

 

BRILLIANT!

Do the reversion waves also come into synchronization?

Texas,
I'd probably need a second pressure transducer to see what they do during a sync.
If they are on the same channel they may fight each other (which may be interesting)
It's already interesting watching the fuel climb up the clear tubing up to the gauge(i had to use the gauge on Sunday as my laptop battery died).
I'll hook up the scope maybe this weekend and see what happens.
