Throttle valve synchronization
Using the vacuum balancer gauge, inspect the throttle valve
synchronization in the same manner as the digital vacuum
tester. Pay attention to the following points:
The vacuum gauge is positioned approx. 45° from the horizontal
level, and in this position the two balls should be within one ball
dia. If the difference is larger than one ball, turn the idle air screw
on the throttle body and bring the ball to the same level.
A correctly adjusted throttle valve synchronization has the balls
in the No. 1 and No. 2 at the same level.

NOTE:
* During balancing the throttle valves, always set the engine
rpm at 1 000 r/min, using throttle stop screw.
* After balancing the four valves, set the idle rpm to 1 000 r/min
by the throttle stop screw.
