  Inspection of the magneto consists essentially of a periodic breaker point and dielectric inspection. After the magneto has been inspected for security of mounting, remove the magneto cover, or breaker cover, and check the cam for proper lubrication. Under normal ... these have an adhesiveness that collects dirt and grime that could foul an otherwise good set of breaker contact points. Figure 4-65. Felt lubricator…

  check and adjust the timing of the breaker points for the S-200 magneto, which does not have timing marks in the breaker compartment: 1. Remove the timing inspection plug from the top of the magneto. Turn the rotating magnet ... place the pointer in the zero position. [Figure 4-52] 3. Connect a suitable timing light across the main breaker points and turn the magnet in its normal direction of rotation 10° as indicated by the pointer. This…
