When visually inspecting your lawn mower’s starter, inspect the wiring and connections of the starter as well as its casing for any signs of corrosion or wear and tear. Look at the starter switch and make sure that it is working properly, as well as all other components connected to the battery and starter motor. Additionally, check the mounting bolts on the engine block and ensure that they are tight enough so that there will be no slipping during operation. Finally, thoroughly examine the flywheel for any damage or missing parts such as magnets or brushes. All these components must be in good condition for a lawn mower’s starter to work properly.
