Resetting the Throttle Control
The following steps can be used to reset the Throttle Control to an
approximate factory “tune”.
Clearing the Throttle Control
☐
With the engine off, rotate the “MAX RPM”, “IDLE DOWN PRESSURE” (IDP) and
“VR IDLE” adjustment screws counterclockwise 20 full turns (Figure 131).
The Throttle Control uses 20 turn adjustment screws, turning the
screws past this point will not damage the Throttle Control.
