🔌 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

  

📦 Condition

  

• Genuine used part

• Removed from running engine where applicable

• In good working condition unless otherwise stated
