But your question doesn't care which gauge type is used. Vacuum goes up as throttle is closed and vice versa. An easy way to recall this is to remember that the engine is a pump sucking air through the carburetor. The more closed the throttle, the more suction in the intake manifold. Vacuum is a measure of this suction. To get a particular vacuum gauge reading to go down, increase the throttle on that carb. To get a particular vacuum gauge reading to go up, decrease the throttle on that carb. -------- Thom Riddle Buffalo, NY (9G0) Kolb Slingshot SS-021 Jabiru 2200A #1574 Tennessee Prop 64x32 Don't accept your dog's admiration as conclusive evidence that you are wonderful.

I understand the relationship of throttle to vacuum - But still am confused as to which carb I should adjust AND when the LED is skewed left of right does this mean higher or lower vacuum ON WHICH SIDE. I've decided to use the right Carb as the Master as the cable run is very short and probably less chance of error. OR question to those who are running a Rotax 912ULS am I again being anal about adjusting when only one led out???
