INSTALLATION
To install the MPU sensor, bar the engine until a
gear tooth on the flywheel lines up in the center of
the mounting hole. Thread the sensor in gently by
hand until it just touches the gear tooth. Back it out
one quarter turn and set the locknut.

Do not use fan blade to bar over en-
gine. That can damage blades and cause prop-
erty damage and personal injury.
