To check:  Remove the spark plug cap.  Clean any dirt from around base of spark plug.  Remove spark plug using wrench (not included).  Inspect spark plug for damage, and clean with a wire brush before reinstalling. If insulator is cracked or chipped, spark plug should be replaced. NOTE: If replacing, use the following recommended spark plug or equivalent: NGK BPR4ES.  Measure plug gap. The correct gap is 0.028−0.031 in. (0.7-0.8 mm). To widen gap, if necessary, carefully bend the ground (top) electrode. To lessen gap, gently tap ground electrode on a hard surface.  Seat spark plug in position; thread in by hand to prevent cross-threading.  Tighten with wrench to compress washer. If spark plug is new, use 1/2 turn to compress washer appropriate amount. If reusing old spark plug, use 1/8 to 1/4 turn for proper washer compression. NOTE: An improperly tightened spark plug will become very hot and could damage the engine. air filter cover screws filter element air filter unit 120V AC/CA 120/240V AC/CA Fig. 11 120V AC/CA CIRDCIUSIYTUBNRTEOARKER ReCtaoirnder ReCtaoirnder oil drainage oil CAP/ bolt dipstick Fig. 12 spark plug spark plug cap Fig. 13 Page 18 - English
