Use Champion N9YC spark plug or equivalent. Replace the plug
once each year. This will help the engine start easier and run
better.
1. Stop the engine and pull the spark plug wire off of the spark
plug.
2. Clean the area around the spark plug and remove it from the
cylinder head.
3. Set the spark plug's gap to 0.70-0.80 mm (0.028-0.031 in.).
Install the correctly gapped spark plug into the cylinder head
(Figure 14).
