Installing the module and setting the air gap
NOTE: If just setting the air gap, loosen the module
mounting screws first then follow the same steps
as described below.
1. Rotate the flywheel so that the magnets are away
from where the module is mounted.
2. Install the module. Do not tighten the module down.
3. Place a non-ferrous feeler gauge between the mod-
ule and the flywheel.
NOTE: The air gap should be 0.016” - 0.024” (0.4-0.6
mm).
4. Rotate the flywheel so that the magnets align with the
legs of the module while holding the feeler gauge in
place.
See Figure 7.13.
5. Tighten the module mounting screws to a torque of
80 - 106 in-lbs (9 - 12 Nm).
6. Rotate the flywheel to remove the feeler gauge.
7. Install the blower housing and starter.
8. Hook the spark plug wire from the clip in the carburetor insulator.
9. Install the Heat box and intake elbow by following the steps described in Chapter 3: Air Intake Systems.
10. Connect the spark plug wire to the spark plug.
11. Test run the engine before returning to service.
