Checking the spark plug caps
1. Remove the spark plug caps from the
spark plug wires by turning the caps
counterclockwise.
2. Measure the spark plug cap resistance.
Replace if out of specification.
Checking the pulser coil air gap
1. Turn the flywheel clockwise to align the
projection of the flywheel with the pulser
coil projection.
2. Measure the gap between both projec-
tions with a thickness gauge. Adjust if out
of specification.
3. Remove the flywheel magnet nut and fly-

4. Loosen the pulser coil screws, adjust the

position, and then tighten
the screws finger tight.

6. Tighten the pulser coil screws and fly-
wheel magnet nut to the specified
torques.
Checking the engine start switch
