## Discrepancy

(CAN) PILOT REPORTED ENGINE NOT DEVELOPING FULL POWER.  GROUND RUN CONFIRMED THIS.  INSPECTION FOUND PIECE OF CARBURETOR HEAT VALVE SEAL MATERIAL (.25 INCH BY 3 INCHES) STUCK AROUND THE VENTURI OF THE CARBURETOR.  THE PIECE WAS REMOVED AND THE  SEAL WAS TRIMMED.  THE ENGINE RUN-UP WAS NORMAL.
