## Discrepancy

A MAGNETO NEWLY OVERHAULED, WOULD NOT SEAT ON THE ENGINE.  FOUND THE BUSHING WHICH CAME INSTALLED ON THE MAGNETO WAS TOO LARGE IN DIAMETER TO CENTER THE BORE OF THE DRIVE GEAR.  COMPARED TO ANOTHER BUSHING .827 INCH, IT WAS .829 INCH.  THE LYC TABLE OF LIMITS SPECIFIES .0015 INCH - .0035 INCH LOOSE FIT.  SUBMITTER STATED USE OF THESE BUSHINGS AND THE RESULTING IMPROPER FIT COULD RESULT IN MAGNETO MALFUNCTION.  (X)
