Stale fuel can cause many problems, including preventing your lawn mower from starting.
Old petrol in your mower can go off in as little as 2-4 weeks, so it’s important to drain your fuel before putting it into storage over the winter months.
How can you tell that it’s stale fuel that’s causing your lawn mower to not start?
Typically there will be fuel in the tank but the engine will not fire up. If the machine has been left for a few weeks, you will probably just have to drain the fuel in the tank and / or carburetor float bowl and replace with fresh petrol.
However, if this doesn’t resolve the issue, cleaning or replacing the carburetor may be necessary.
This type of repair would not be covered under warranty so it is important to drain your petrol before long periods of storage.
