  If your McCulloch Lawn Mower engine won't start, there could be several reasons. First, make sure the fuel tank is filled. If that's not the issue, the spark plug might be faulty and need replacement. Also, check the spark plug connections to ensure they are secure and the cables aren't interchanged. Other potential causes include dirt in the carburettor or fuel line, which requires cleaning, a faulty starter motor needing investigation, or contaminated fuel in the tank that should be emptied and refilled with fresh fuel. Finally, ensure you are using the correct fuel type.

  If your McCulloch Lawn Mower is mowing unevenly, the blades might be blunt and need sharpening. Long or wet grass can also cause this, so mow when the grass is dry and at an appropriate height.
