Pete, the way to use the Unisyn is to open the throat up so that there
is a minimum of interference with the airflow. Put it on the intake
(centered), and dial in the throat until you get the ball in the middle of
the guage. You will get a small amount of idle decrease, but no worries.
Then, move the Unisyn to the other carb intake and see where the ball lies.
Adjust the idle of the lowest flowing carb to match the higher one. When
matched, look at your idle RPM, decide if it needs to go up or down
(probably down), and lower the idle of each carb until the preferred idle
speed is met. No Worries!
