It be nice if we could put a single small sensitive gauge in our panels that
could tell us when our 912 carbs were out sync and allow us to make
adjustments without having hook up temporary gauges "under the hood". Yes,
I know we can feel it when the carbs are not in sync, but if they are just a
little off, or when I am not certain if a rough running engine is due to
sync problems, a panel instrument would be very helpful. Does such a dual
pressure differential gauge/sensor exist?

Yes,
I have thought of the same thing but that would be some long vacuum hoses
for me. I have an Aventura II and the engine is up in the back on the wing.
I wonder if it would work?

Sorry guys, won't work. You have the cross over balance tube from carb to carb. That would throw off any real worth while reading.

I am in total agreement with an in panel gauge. Maybe you could come up with some sort of valve in the cross tube(of course it would probably leak air). I have a knob on the back of one of my throttle cables and can make micro adjustments on the carb sync without ever getting out of the aircraft.It does a great job of syncing one carb to the other. But alas, I have to have the gauge(I use a Twin Max) to get it "on the money"
Maybe someone will invent something.

You would have to also install a centre valve in the cross tube to be able to shut down the cross flow make a reading. As for leaks not properly installed. My beef would be more weight.
