# Flywheel magneto

> The flywheel is the heavy rotating disc on the crankshaft that carries magnets; with the stator it generates electricity and smooths engine rotation.

A trigger lug on the flywheel's outer surface produces the [ignition](https://motorsikletparcasi.com/en/glossary/cdi) signal. On most engines the [starter clutch](https://motorsikletparcasi.com/en/glossary/starter-clutch) is bolted to the back of the flywheel. Its mass helps the engine run smoothly at low revs.

- Use a proper flywheel puller; hammering it off damages the crankshaft and magnets.
- A sheared woodruff key shifts the ignition timing, causing hard starting or kickback.
- A loose or broken magnet can rub on and damage the [stator](https://motorsikletparcasi.com/en/glossary/stator).
