Why won't my Toro DH 220 engine start, starts hard, or fails to keep running?

Several factors can cause this issue. Make sure you are sitting on the seat and that the fuel tank isn't empty. Check if the air cleaner is dirty and either clean or replace it. Ensure the spark plug wire is securely connected to the spark plug, and that the spark plug isn't damaged or incorrectly gapped—replace it if needed. Also, ensure the choke is closing properly by adjusting the throttle cable. Check the fuel filter for dirt and replace if needed. Finally, check that the fuel shut-off valve is open.
