Spark Plug

Spark Plug Inspection

Using a non-recommended spark plug can result in serious engine damage. Always use recommended spark plugs. Refer to the Specification section for the recommended spark plug type. Always torque spark plugs to the specification.
In order to service the spark plug, the provided spark plug wrench is required.
caution
A hot exhaust system and engine can cause burns. Wear protective gloves when removing a spark plug for inspection.
IMPORTANT
To ensure proper engine operation, the spark plug must be free of deposits and properly gapped. If the engine has been running, allow it to cool before servicing.
The spark plug can be accessed through the spark plug access door at the top of the generator, or by removing the maintenance panel.

  1. Remove two screws from spark plug access door.
  2. Remove the spark plug cap .
  3. Clean any dirt from around the base of the spark plug.
  4. Using the provided park plug wrench, remove the spark plug.
  5. Inspect the electrode for wear and carbon buildup. Look for a sharp outer edge with no rounding or erosion of the electrode.
  6. Inspect spark plug. Replace if electrodes are worn or if insulator is cracked, chipped, or fouled.
  7. Clean the spark plug with a wire brush if it is to be reused.

Normal Plug

The normal insulator tip is gray, tan or light brown. There will be few combustion deposits. The electrodes are not burned or eroded.
This indicates the proper type and heat range for the engine and the service.

Wet Fouled Plug

The wet fouled insulator tip is black. A damp oil film covers the firing end. There may be a carbon layer over the entire nose. Generally, the electrodes are not worn. Fouling may be caused by excessive oil or by frequent short trips, especially in cold weather.

Spark Plug Replacement

IMPORTANT
Prior to replacing the spark plug, complete the inspection steps outlined on Spark Plug Inspection.

  1. Open the maintenance cover.
  2. Remove the spark plug cap.
  3. Clean any dirt from around the base of the spark plug.
  4. Using the provided park plug wrench, remove the spark plug.

  1. Using a wire-type feeler gauge, measure the spark plug electrode gap. If necessary, correct the gap by carefully bending the side electrode.
    MEASUREMENT

    Spark Plug Gap

    0.024- 0.028 in (0.6-0.7 mm)
  2. Ensure the spark plug sealing washer is in good condition and thread the spark plug in by hand to prevent cross-threading.
  3. After a new spark plug has been seated by hand, it should be tightened 1/2 turn with a wrench to compress the sealing washer. If a used plug is being reinstalled, it should only require 1/8 to 1/4 turn after being seated.
  4. Re-install the spark plug cap and close the maintenance cover.
    NOTICE

    A loose spark plug can overheat and damage the engine. Over tightening the spark plug can damage the plug threads.

    Never use a spark plug with an improper heat range.
