An ‘Overcrank’ error indicates the generator failed to start after multiple attempts. Possible causes include:

1. Fuel Issues: Check for adequate fuel and ensure fuel lines are clear.
2. Air Intake: Inspect the air filter for clogs that could restrict airflow.
3. Spark Plugs: Worn or fouled spark plugs can prevent starting; examine and replace if needed.

After addressing these areas, clear the error code and attempt to restart the generator. If the error persists, professional service may be required.
