How do I know if my lawn mower spark plug is bad?
It may be time to replace your spark plug if:
- The engine is dying or failing.
- You have to add more gas than usual.
- The spark plug is visibly damaged and broken.
- You’re having a harder time getting the lawn mower to start.
If you suspect your lawn mower's spark plug has gone bad, hire a pro to confirm your suspicions. A repair technician can identify the problem and perform repairs.
