If engine is down on power, difficult to

start or runs poorly at idling speed, first

check the spark plug.

Fit a new spark plug after approx. 100

operating hours or earlier if the

electrodes are badly eroded.

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 result in trouble in operation.

Remove the spark plug

N Move the Master Control lever to the

stop position 0

N Turn the knob above the rear handle

in the direction of the arrow and

remove the carburetor box cover
