Why Challenge XSZ40E engine does not start?
- Ttravis17Aug 5, 2025
If your Challenge Lawn Mower's engine won't start, there are several possible reasons. First, make sure you are pressing the start/stop bar. Also, check if the primer bulb is empty and press it 3-5 times. The spark plug might be defective and need replacing. Ensure the fuel tank isn't empty and refill it if necessary. Finally, the engine may be flooded; if so, remove the plug and dry it.
