Replacing the Spark Plugs

Service Interval: Every 800 hours
Type: Champion RC14YC (or equivalent)
Air Gap: 0.76 mm (0.030 inch)
Note: The spark plugs usually lasts a long time; however,
you should remove and check them whenever the engine
malfunctions.
1. Clean the area around each spark plug so that foreign
matter cannot fall into the cylinder when the spark
plug is removed.
2. Pull the spark-plug wires off the spark plugs and
remove the plugs from the cylinder head.
3. Check the condition of the side electrode, center
electrode, and the 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 the 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.
4. Set the air gap between the center electrode and side
electrodes to 0.76 mm (0.030 inch); refer to
Install the correctly gapped spark plug with the gasket
seal, and tighten the plug to 23 N-m (200 in-lb). If a
torque wrench is not used, tighten the plug firmly.
