Why my Qualcast XSZ51A-SD Lawn Mower engine does not start?

If your Qualcast Lawn Mower engine won't start, make sure that you press the start/stop bar. Check if the primer bulb is empty and, if so, press it 3 to 5 times. Also, check that the fuel tank is not empty and refill it with fuel if needed. The spark plug could also be defective, so replace it. If the engine is flooded, remove the plug and dry it.
