As part of the basic servicing to keep your petrol mower running smoothly, it is recommended that your spark plug is replaced every season for easy starting. If you have your mower serviced by an authorised dealer then this will be part of the work they carry out. If you’re not having a professional service carried out though, this is an easy task you can do yourself at home to give your lawn mower a new lease of life. We’ve put together a short video aout how to change a lawn mower spark plug to show you how it’s done.
