Old fuel can leave deposits that block tiny carburettor passages. This leads to hard starting, surging, hunting and poor throttle response.
What to watch for
If your machine is hard to start, runs rough, vibrates, leaks fuel or feels unsafe, stop using it and get it checked. Early repairs are often cheaper than running a machine until it fails completely.
