1. Check the fuel level. Make sure the mower has enough fuel in the tank. If the fuel level is low, add more fuel and try starting the mower again.
2. Check the oil level. Make sure the mower has enough oil in the crankcase. If the oil level is low, add more oil and try starting the mower again.
3. Check the spark plug. Remove the spark plug and check for any damage or wear. If the spark plug is damaged or worn, replace it and try starting the mower again.
4. Check the air filter. Remove the air filter and check for any dirt or debris. If the air filter is dirty, clean it and try starting the mower again.
5. Check the drive belt. Inspect the drive belt for any damage or wear. If the drive belt is damaged or worn, replace it and try starting the mower again.
6. Check the battery. If your mower is electric, check the battery to make sure it is properly charged. If the battery is low, charge it and try starting the mower again.
7. Check the throttle control. Make sure the throttle control is in the correct position. If the throttle control is not in the correct position, the mower will not start.
If you have checked all of these things and the mower still does not start, you may need to take it to a lawn mower repair shop for further diagnosis and repair.
