Ignition System
Description
Models 42, 42D and 242 are equipped with an
electronic ignition system. The spark generated
by this system has a higher energy and a
shorter burning time than the spark generated
by a breaker point ignition. Because of this, the
spark, across the spark plug electrode,
appears to be weaker.
0.5mm (.020”)
Checking the Spark
Remove and clean spark plug. Check spark
plug electrode gap.
Spark plug gap should be 0.5 mm (.020”). If
electrodes are worn, spark plug must be
replaced.
With ON/OFF switch in “ON” position, ground
spark plug to cylinder and pull starter handle. A
spark should appear across the electrodes.
