Replacing the Spark Plugs

Service Interval: Every 400 hours
The spark plugs usually last a long time; however, remove and
check the plugs whenever the engine malfunctions or every
400 hours. Replace the spark plugs to ensure proper engine
performance and reduce exhaust emission level.
The correct spark plug to use is a Champion RC 14YC or
NGK BPR 4ES.
1. Clean the area around the spark plugs so foreign matter
cannot fall into the cylinder when you remove the
spark plug.
2. Pull the wires off the spark plugs and remove the plugs
from the cylinder head.
3. Check the condition of the side electrode, center
electrode, and center-electrode insulator to ensure that
there is no damage.
Important: A cracked, fouled, dirty, or otherwise
malfunctioning spark plug must be replaced. Do
not sand blast, scrape, or clean electrodes by using
a wire brush because grit may eventually release
from the plug and fall into the cylinder. The result
is usually a damaged engine.
