4.9 Using Ignition Tester

See Graphic: wc_gr002884

A more accurate test of the ignition module can be made using ignition

tester P/N 78836 (a).

4.9.1 Preset gap to 4.2 mm (0.166 in.) (b).

4.9.2 Attach the end of the ignition cable to one end of the tester. Ground the

other end of the tester by clipping it onto the engine cylinder. Crank the

engine using the rewind starter or by spinning the flywheel. If a spark

jumps the test gap, the ignition system is operating satisfactorily.

Note: A minimum of 500 rpm is required to produce spark.
