RELATIONSHIP BETWEEN MACHINE TROUBLE SYMPTOMS AND RELATED PARTS EXTRACT:
Symptoms in machine operation when trouble occurs..

EC Motor

Even if engine control dial is turned, engine speed does not increase from slow idle speed.
• Engine start may be difficult though starter rotates. Engine will stall if discontinuity occurs in EC motor while engine is running at more than a specified speed.
• Engine will become uncontrollable if discontinuity occurs in EC motor while engine is running at lower than a specified speed. Engine cannot be stopped with key switch.

EC Sensor

Error in setting will seldom occur so that change in machine operation will not be noticed.
• In case error is set on lower side, engine speed changes but runs slower than normal through the full range when engine control dial is turned. (Note: In case error is set on upper side, EC motor is driven so that it runs faster than the control range. However, motor, a worm gear type, holds governor lever at maximum constant position, preventing engine stall. When engine control dial is turned to minimum speed position, governor lever is returned to idle position.) When starting engine, engine speed fluctuates.
• Starting engine is occasionally difficult.
