## Discrepancy

PILOT REPORTED THAT THE TACHOMETER WAS INDICATING 100 RPMS HIGHER THEN RECOMMENDED BY THE ENGINE MANUFACTURE AFTER TAKEOFF PILOT HAD NO CONTROL OF THE PROPELLER GOVERNOR.  PILOT REDUCED ENGINE POWER TO KEEP RPMS BELOW REDLINE AND THEN COULD NOT MAINTAIN ALTITUDE.  REMOVED GOVERNOR FROM SERVICE AND SENT OFF FOR EVALUATION, THIS EVALUATION DETERMINED THAT THERE WAS INTERNAL OIL LEAKAGE OF OIL PRESSURE CAUSING THE UN-COMMANDED PROPELLER RPM FLUCTUATION.
