(7) Install timer head on base (par. [86 c] (11)).
(8) Connect spark control wire to timer lever and adjust (par. [88]).
(9) Connect battery negative post wire to frame ground terminal.
(10) Swing air cleaner bracket back into place and install two bolts, washers, and nuts securing bracket to frame clips.
(11) Replace timer cover and check engine for starting.
88. ADJUST SPARK CONTROL.
a. Spark advance and retard is controlled by left handle bar grip. Spark lever operates within a quadrant mounted on engine. Spark must be fully advanced (lever inward toward engine) when handle bar grip is turned inward to full extent of its travel. When handle bar grip is turned outward, spark lever retards (lever outward away from engine).
(1) With control wire in lever stud and clamp screw loose, turn left grip fully inward; then back it out just a little.
(2) Shift spark lever inward toward engine as far as it will go; then tighten control wire clamp screw. Test by turning left grip fully inward and noting position of spark lever. It should be against inner side of quadrant ([fig. 51]). Retard spark and check position of lever within quadrant; it should be against outer side of quadrant.
(3) Check final adjustment. Readjust full advance and retard timer lever positions as necessary when left grip is turned inward, and outward, respectively.
