ment, or repair to the unit, disconnect the wire to the
spark plug. Remove the wire from the spark plug to
prevent the engine from starting by accident.
tf a drive belt becomes worn or after the installation of a new drive
belt, the speed control lever may need an adjustment. When the

lever was in the NEUTRAL position, then turn the adjuster nut
