Type: Champion RN14YC (or equivalent)
Air Gap: 0.030 inch (0.762 mm)
Checking and Replacing the Spark Plug
Note: The spark plug usually lasts a long time; however,
the plug should be removed and checked whenever the
engine malfunctions.
1. Clean the area around the spark plugs so that foreign
matter cannot fall into the cylinder when the spark plug
is removed.
2. Pull the wires off of 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 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.
4. Set the air gap between the center and side of the
electrodes at 0.030 inch (0.762 mm) (Fig. 41). Install
the correctly gapped spark plug and tighten the plug to
14 ft.-lb. (20 N⋅m).
