## Discrepancy

SERVO WAS OVERHAULED ON APPROXIMATELY 1-28-97.  COMPONENT OPERATED WITHOUT PROBLEM UNTIL 5-11-97 WHEN IT HAD ACCUMULATED 30 HOURS IN SERVICE.  ON 5-11-97, EXPERIENCED IN-FLIGHT ENGINE ROUGHNESS WHICH ABATED SOMEWHAT WITH EXCESSIVELY LEANING OF THE MIXTURE.  UPON LANDING, ENGINE POWER COULD NOT BE SUSTAINED DUE TO EXCESSIVELY RICH MIXTURE.  UPON DISASSEMBLY, FOUND THAT SEAL PN 2539561 WAS LEAKING FUEL INTO THE AIR CHAMBER.
