The timing of the spark is controlled by the location of the flywheel magnet group as referenced to engine top
dead center.

The CD ignition systems are designed to be trouble
free for the life of the engine. Other than periodically
checking/replacing the spark plugs, no maintenance
or timing adjustments are necessary or possible.
Mechanical systems do occasionally fail or break
down however, so the following troubleshooting
information is provided to help you get to the root of
a reported problem.

Reported ignition problems are most oen due to
poor connections. Before beginning the test procedure,
check all external wiring. Be certain all ignition-related
wires are connected, including the spark plug leads.
Be certain all terminal connections fit snugly. Make
sure the ignition switch is in the run position.
NOTE: The CD ignition systems are sensitive to
excessive load on the kill lead. If a customer
complains of hard starting, low power,
or misfire under load, it may be due to
excessive draw on the kill circuit. Perform the
appropriate test procedure.

Isolate and verify the trouble is within the engine
ignition system.
1. Locate the plug connectors where the wiring
harnesses from the engine and equipment are
joined. Separate the connectors and remove the
white kill lead from the engine connector. Rejoin
the connectors and position or insulate the kill
lead terminal so it cannot touch ground. Try to
start the engine to verify whether the reported
problem is still present.
NOTE: If the engine starts or runs during any of
the testing, you may need to ground the
kill lead to shut it down. Because you have
interrupted the kill circuit, it may not stop
using the switch.
