Make sure the air gap between the center and side
electrodes is correct before installing the spark plug. Use a
spark plug wrench for removing and installing the spark
plug(s) and a gapping tool/feeler gauge to check and
adjust the air gap. Install a new spark plug(s) if necessary.
Type: NGK BMR-4A, Champion RCJ–8 or equivalent
Air Gap: 0.025 inch (0.65 mm)
Removing the Spark Plug
1. Park the machine on a level surface and disengage the
blade control (PTO).
2. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
3. Pull the wire(s) off the spark plug(s) (Fig. 28). Now
clean around the spark plug(s) to prevent dirt from

Checking the Spark Plug
1. Look at the center of the spark plug(s) (Fig. 29). 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.
Important Never clean the spark plug(s). Always
replace the spark plug(s) when it has: a black coating,
worn electrodes, an oily film, or cracks.
2. Check the gap between the center and side electrodes
(Fig. 29). Bend the side electrode (Fig. 29) if the gap is
not correct.
