A dirty air filter decreases the amount of air supplied to the engine. This can lead to an increase in fuel consumption which is something we are all keen to avoid. It can also turn into a sooty black residue which then begins to impact on the spark plugs, in turn reducing their efficiency. If this is the case with your petrol mower, you will hear irregular engine noises.When you finally have the opportunity to get into your garden to tackle those overdue projects, or even just a bit of standard tidying, it is important that your mower is in good working order and ready to go.
