How It’s Used
The magneto is mounted near the flywheel and generates electrical current as the flywheel rotates. This current is sent to the spark plug to ignite the air-fuel mixture.
Maintenance Tips
- Replace if engine has no spark or intermittent ignition
- Check spark plug and wiring before replacement
- Set correct air gap during installation
- Keep ignition components clean and properly aligned
