## Discrepancy

OPENED MAGNETO TO TROUBLESHOOT TIMING PROBLEM.  FOUND COIL TAB BENT AT DOWNWARD ANGLE SUFFICIENT TO CAUSE STEEL BARREL OF CARBON BRUSH HOLDER TO BE ROTATING ON COIL TAB, DAMAGING IT SUBSTANTIALLY.  THE SLICK MANUAL CALLS FOR FLUSH TO .0312 INCH FROM THE PARTING SURFACE.  UPON LEVELING THE COIL TAB, IT WAS FLUSH WITH THE SPACERS USED ON THE 4347 (M3826) AND NOT THE PARTING SURFACE.  THIS PROBLEM WAS UNRELATED TO THE TIMING PROBLEM.
