If your lawnmower starts with starting fluid but won’t stay running, it usually indicates a fuel supply problem. The engine is getting an initial burst of fuel from the starting fluid but then fails to receive a steady supply afterwards. Check and clean the carburetor, as it may be clogged. Also, inspect the fuel filter and lines for blockages or leaks. It's essential to ensure the fuel is fresh and the fuel system is clean for optimal operation.
