## Discrepancy

DISTRIBUTOR ARM COMING LOOSE FORM THE GEAR.  WHEN THE ARM COMES LOOSE, IT CAUSES WEAR ON THE ARM CTR AND AS THE CTR WEARS TO A LARGER DIAMETER HOLE, THE ARM FLIES OUT CLOSING THE GAP AND GRINDS INTO THE CONTACTS OF THE DISTRIBUTOR BLOCK.  THE MAG RAN NORMAL AND WAS FOUND DURING AN INSPECTION.
