🔌 Function

The magneto plate supports and positions ignition components under the flywheel so the ignition system can generate and trigger spark at the correct timing point.

⚠️ Common Signs of Failure

• No spark
• Weak or intermittent spark
• Ignition timing unstable
• Engine hard to start
• Misfire at idle or under load
• Plate damaged, cracked or loose
• Worn sleeve allowing excess movement
• Spark returns after fitting a known-good magneto plate assembly
