Servicing The Engine Fuel System - Toro 34215 Operator's Manual

Checking the Spark Plug
Important: Do not clean the spark plug(s). Always
replace the spark plug(s) when it has a black coating,
worn electrodes, an oily film, or cracks.
If you see light brown or gray on the insulator, the engine is
operating properly. A black coating on the insulator usually
means the air cleaner is dirty.
Set the gap to 0.6 to 0.7 mm (0.02 to 0.03 inch).
