Support both inspection advice and global parts supply for remote projects
This is often caused by a failed 2523-9016 throttle motor. When the internal gears or electronic sensors inside 25239016 wear out, the signal from the controller cannot be translated into mechanical movement. We recommend checking the wiring harness first; if the signal is reaching the motor but it fails to move, a replacement is necessary.
Ensure the machine is powered off. Locate the actuator near the engine fuel pump. Disconnect the electrical plug and mounting bolts. Install the new 2523-9016 unit. Note: Some models may require a simple calibration via the monitor panel to sync the new motor with the engine idle settings.
