## Discrepancy

INVESTIGATION FOR DETERIORATED LT MAG FOUND LEFT MAG WAS (PRESSURIZED) FROM SAME 'T' FITTING AS RIGHT MAG BUT HAS MORE HEAT.  LEFT MAG HAS B AND D TACHOMETER PICK UP WITH LARGER ORIFICE WHICH ALLOWS ALMOST TWICE THE AIRFLOW ALLOWING MORE HEAT INTO MAG.  SUBMITTER STATED SLICK REPORTED OVER 1 YR AGO THEY WERE AWARE OF PROBLEM AND IT WOULD BE CORRECTED.  THIS IS THE 2ND TIME HAVE HAD THIS PROBLEM WHICH IS SHARED BY MANY MOONEY OWNERS.
