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).
