Why Your Lawn Mower Will Not Start

The most common reasons are stale fuel, dirty carburettor passages, a fouled spark plug, restricted air filter, low oil issues, blocked fuel flow or safety cable problems. A proper diagnosis saves guesswork.

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.
