Why is my Mantis Tiller engine noisy or knocking?
- AAlex MillerSep 6, 2025
If your Mantis Tiller engine is noisy or knocking, the spark plug might be in the incorrect heat range; replace it with plugs specified for the engine. Alternatively, the bearings, piston ring, or cylinder walls may be worn, requiring you to contact your local authorized dealer.
