tighten it securely.
10. Wipe up any spilled oil.

Servicing the Spark Plug

Service Interval: Yearly—Service the spark plug and
replace it if necessary.
Use a Toro spark plug (Part No. 119-1961).
1. Stop the engine and wait for all moving parts to stop.
2. Disconnect the wire from the spark plug (Figure 13).
3. Clean around the spark plug.
4. Remove the spark plug from the cylinder head.
Important: Replace a cracked, fouled, or
dirty spark plug. Do not clean the electrodes
because grit entering the cylinder can damage
the engine.
5. Set the gap on the plug to 0.030 inch (0.76 mm)
(Figure 31).
