What was found
(CAN) WHILE PERFORMING A ROUTINE 500 HR INTERNAL MAGNETO INSPECTION THE DISTRIBUTOR FINGER WAS FOUND TO BE LOOSE IN THE DISTRIBUTOR GEAR, PN M3008. THIS IS A PROBLEM THAT WAS COMMON TO THE EARLIER SERIES MAGNETOS OF 20 YEARS AGO. A DISTRIBUTOR GEAR FINGER THAT IS LOOSE WILL STILL OPERATE BUT AS WEAR CONTINUES THE DISTRIBUTOR GEAR FINGER COULD COME OFF AT WHICH POINT THE MAGNETO WILL NOT OPERATE.
