I was hoping someone could help. Here are the symptoms:

1. Overfilled with oil, started choking and losing power. Eventually stopped and won't start.
2. Oil was changed and new filter was installed.
3. Still won't start. The starter turns and it feels like it wants to start but it won't ignite.
4. Checked the battery (full) and the spark plug.
5. The spark plug has no spark. There is voltage (12.2V) and I managed to electrocute myself while checking, but the engine won't start.
6. Checked compression by placing my finger over the spark plug hole. That was fine.

Anyone any ideas?
