uenced by:
○
An incorrect carburetor setting.
○
Wrong fuel mixture (too much oil in the gasoline)
○
A dirty air
fi

○
Hard running conditions (such as cold weather).

check the spark plug

it and check the electrode gap. Readjust if necessary.
The correct gap is 0.024” (0.6 mm). The spark plug
should be replaced after about 100 operation hours or
earlier if the electrodes are badly eroded.
