## Discrepancy

PILOT REPORTED THAT HE LOST CONTROL OF E2 DURING CLIMB OUT, ENG WAS UNRESPONSIVE TO THROTTLE MOVEMENT.  PILOT SHUT DOWN & SECURED ENG.  MX FOUND THAT THE THROTTLE ADJUSTMENT LINKAGE WAS LOOSE ON THE SERVO, DUE TO IMPROPER INSTALLATION, CAUSING THE ADJUSTMENT SERRATIONS NOT ENGAGE ONE ANOTHER.  THROTTLE LEVER MOVEMENT WAS NOT BEING MECHANICALLY TRANSMITTED TO FUEL SERVO.  FUEL SERVO WAS CHANGED FOR OVERHAUL ON THE PREVIOUS DAY.
