摘要： PROBLEM TO BE SOLVED: To provide an engine working machine capable of preventing stopping of an engine by fogging of a spark plug, while suppressing an increase in an engine speed when starting.SOLUTION: When it is detected that the engine exceeds a predetermined engine speed slightly lower than a clutch engagement rotational speed while it is detected that a throttle opening is set to a starting position in starting the engine, a control means delays the ignition timing to a first angle (-25 degrees) from an ordinary angle (for example, BTDC 25 degrees), and also advances the ignition timing to a second angle (+10 degrees) for a specific period (for example, by one cycle) at a specific interval (for example, by 10 cycles), and thereby, the stopping of the engine, which is caused by the fogging of the spark plug, is prevented while the engine speed is controlled to be not higher than a centrifugal clutch engagement rotational speed.
