## Discrepancy

DURING INSP CYCLE, MAGNETO TIMING NOTED TO BE ADVANCED 3 DEGREES (ENGINE TO MAG TIMING FOUND AT 28 DEGREES).  PREVIOUS COMPLIANCE WITH SB2-08B CONFIRMED. CAPACITOR COVER REMOVED FOR INSP,  WAS FOUND THAT MAIN POINT BRASS ASSY SCREW WAS LOOSE.  THIS CAUSED THE SPRING STEEL ARTICULATION ARM TO MOVE OUT OF POSITION AND AFFECT MAGNETO TIMING.  ARTICULATION ARM RE-ALIGNED AND SCREW TORQUED TO 25 IN LBS.  NO WEAR FOUND ON CAM PADDLE OR CARBON BRUSH.  MAGNETO RE-ASSEMBLED IAW L1363E.
