Servicing A Kohler Engine - Toro TITAN HD 1500 Series 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 0.75 mm (0.03 inch).

check for loose or damaged components. Replace all
bent or damaged air-cleaner components.
