Plug
Important:
Always replace the spark plug(s)
when it has a black coating, worn electrodes, an
oily film, or cracks.
1. Clean the spark plug with a wire brush to remove
any carbon deposits.
Use carburetor cleaner to wash the plug and
ensure any foreign matter has been removed.
2. Inspect the spark plugs for cracks, worn
electrodes, black coating, or oily films or other
wear or damage.
3. Replace the spark plug if necessary. Replace all
spark plugs if only one requires replacing.
4. Check the spark plug gap and reset if necessary.
To change the gap, bend only the side-electrode,
using a spark plug tool.
Set the gap to 0.75 mm (0.03 inch).
