14. First, set the timing as described in Part A, Chapter 3, Section 6". When you are finished, before removing the timing pin, make a line across the top of the flywheel with a piece of chalk or other suitable marking device and put a corresponding mark across from it on the engine case, as shown in Fig. 145. Removing the timing pin.

15. Connect the timing light to the plug wire, and if it is the type that needs an external source of power, provide that source (battery, wall outlet, etc.) according to its need.

FIG. 145

16. Start the engine and let it idle. Aim the timing light at the flywheel, as shown in Fig. 146, and watch the marks. The mark on the flywheel will be slightly to the right of the mark on the case. Accelerate the engine to approximately 6000 R.P.M. At that point the timing will have fully advanced and the mark on the flywheel and the mark on the case should appear to be aligned.
 

FIG. 146

17. If the marks did not align, turn off the engine and adjust the timing by removing the flywheel and rotating the stator. If the mark on the flywheel was to the right of the mark on the case, turn the stator counterclockwise an equivalent amount. If the mark on the flywheel was to the left of the mark on the case, turn the stator clockwise an equivalent amount. Reinstall the flywheel and check the timing again with the light.

18. If the mark on the flywheel was erratic and seemed to fire almost anywhere, or jump around quite a bit, replace the magneto.
