REPLACING THE SPARK PLUG
Use a Champion RCJ6Y spark plug (or equivalent). The
correct air gap is 0.025 in. (0.655 mm.). Remove the plug
after every 50 hours of operation to check its condition.
1. Stop the engine and allow it to cool. Grasp the plug
wire firmly and pull the cap from the spark plug.
2. Clean dirt from around the spark plug. Remove the
spark plug from the cylinder head by turning a 5/8 in.
socket counterclockwise.
Note: Replace cracked, fouled or dirty spark plug.
3. Set the air gap at
0.025 in. (0.655 mm.) using a
feeler gauge (Fig. 24).
CAUTION: Do not sand blast, scrape, or
clean electrodes. Grit in the engine could
damage the cylinder.
