THE ACFT WAS ENGAGED IN AN AERIAL APPLICATION FLT WHEN THE ENG LOST POWER. THE PLT MADE A FORCED LANDING IN A BEAN FIELD. DURING THE LANDING ROLL, THE ACFT STRUCK A LEVEE THAT WAS OBSCURED BY HIGH VEGETATION & NOSED OVER. A POST-ACCIDENT INVESTIGATION REVEALED THE CARBURETOR NEEDLE VALVE SEAT WAS LOOSE & ALLOWED FUEL TO BYPASS THE VALVE & ENTER THE INTAKE MANIFOLD. AN INTERVIEW WITH PERSONNEL THAT OVERHAULED THE CARBURETOR REVEALED THAT RECOMMENDED TORQUE VALVES WERE NOT BEING USED DURING INSTALLATION OF THE NEEDLE VALVE SEAT.
