Tighten the nuts to the following torque. ... 6 ± 1 N·m (4.4 ± .7 lb ft)

(2) Transformer assembly

(3) Extension assembly

(4) Spark plug

Tighten the spark plug in the cylinder head to the following torque. ... 68 ± 4 N·m (50 ± 3 lb ft)
Spark plug gap ... 0.29 ± 0.04 mm (.011 ± .002 inch)

Note: A new gasket should be used when a spark plug is installed. Install the spark plug gasket with the tangs toward the sealing face of the spark plug.
