Timing Check Procedures
1, The ignition timing check hole is in the starter recoil/magneto housing. Remove the check plug.
NOTE: The ignition timing marks are stamped on the outside of the flywheel. Ignition timing must be inspected
with the engine at room temperature (68°F / 20° C).
2. With the transmission in neutral, start the engine and set engine speed to 3000 +/- 200 RPM (3500
±
200 RPM
for EH42PL, EH50PL).
3. Direct the timing light at the ignition timing check hole and check the ignition timing. NOTE: Do not allow the
engine to warm up. The timing will retard approximately 2° when the engine is warm.
If the ignition timing is not within the specified range, adjust the stator plate position as described below.

retards (delays) the ignition timing. Moving the plate counterclockwise advances it.
