Balance Throttles Screen
The balance throttles screen shows the vacuum value of each throttle in mmHg. In
addition, when the throttles are balanced to an acceptable range of each other the
words 'THROTTLES BALANCED' in green text will appear on the right of the screen. At
this point, no further adjustment is necessary or productive.
If the throttles are not balanced to each other the words 'THROTTLES UNBALANCED'
in red text will appear on the right of the screen. At this point adjustment will be
necessary.
The adjusters operate on the outer cylinders only (cylinders 1 and 3). The centre
throttle (cylinder 2) adjustment is fixed, this being controlled by the throttle control
motor. Note that the centre reading may alter slightly as the two outer cylinders are
adjusted.
DO NOT attempt to adjust the throttle stop screws, located below the fuel rail. The
stop screws are set at the factory during manufacture, and must not be adjusted.
