(1) Ignition control

(2) Tighten the bolt and the nut on the strap assembly to the following torque. ... 25 ± 6 N·m (18 ± 4 lb ft)

(3) Ignition transformer

(4) Extension assembly

(5) 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.

Tighten the nut for the connectors to the transformers, the combustion buffer and the ignition control. Tighten the nut in a clockwise motion. Use 6V-0006 Electrical Connector Pliers to tighten the connectors more than hand tight.

(6) High voltage terminal

(7) Flange (ground)

Test the high voltage side of the transformer by measuring the resistance between the high voltage terminal (6) and the flange (7) .

High voltage resistance ... 5,000 to 12,000 ohms

Test the low voltage side of the transformer by measuring the resistance between Pin (A) and Pin (B) of the transformer.

Low voltage resistance ... 0.2 to 2.0 ohms
