Exhaust emissions are controlled by the
design of the engine and components
(e.g. carburation, ignition, timing and
valve or port timing).
Adjusting Idle Speed
Engine stops while idling:
N Turn the idle speed screw (LA)
slowly clockwise until the engine
runs smoothly.
If there is a loss of engine power, the
machine is difficult to start or runs poorly
at idle, first check the spark plug.
Install a new spark plug after
approximately 100 operating hours or
earlier if the electrodes are
eroded/corroded.
The wrong fuel mix (too much engine oil
in the gasoline), a dirty air filter and
unfavorable running conditions (mostly
at part throttle etc.) affect the condition
of the spark plug. These factors cause
deposits to form on the insulator nose,
which may degrade performance.
Removing the Spark Plug
N Loosen the screw (1).
N Remove the cover (2).
N Pull off the spark plug boot (3).
N Unscrew the spark plug (4).
