Prevention Tip: Store mower indoors reducing moisture exposure around ignition system components.

Sudden Loss Of Ignition Spark

Quick Check: Test spark output using approved ignition tester before further engine diagnosis.

Fix Suggestion: Inspect the magneto armature, ignition wiring, and connections for damage affecting spark generation.

Prevention Tip: Protect ignition wiring from abrasion near moving engine components during maintenance.

Engine Stalls Unexpectedly

Quick Check: Monitor engine operation after warming checking for sudden ignition interruptions.

Fix Suggestion: Check the magneto armature condition and air gap to maintain reliable spark during engine operation.

Prevention Tip: Perform routine engine maintenance identifying ignition concerns before speed noticeably declines.
