Spark Plug Inspection and Replacement

2.Remove the spark plug cap (B).

3.Clean any dirt from around the base of the spark plug.

4.Using a spark 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.

Inspect electrode for wear and buildup

6.Inspect spark plug. Replace if electrode is worn or if the insulator is cracked, chipped, or fouled.

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

bending the side electrode. The

Spark plug gap

gap should be 0.6 - 0.7 mm

 

(0.024 - 0.028 in).

 

8.Ensure the spark plug sealing washer is in good condition and thread the spark plug in by hand to prevent cross-threading.

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

9.After a new spark plug has been seated by hand, it should be tightened 1/2 turn with a wrench to compress its washer. If a used plug is being reinstalled, it should only require 1/8 to 1/4 turn after being seated.

10.Re-install the spark plug cap (B).

11.Re-install the top of the generator by inserting and tightening the 4 bolts (A) through the handles.
