Gauge and do not remove magneto frame from T-125 assembly fixture.
NOTE: Retard points are set in reference to primary point settings. The lag angle on
the magneto dataplate is the retard breaker’s retard angle measured in
degrees. Use the following procedure to set the retard points the required
number of degrees from the primary points.
