Why does my Toro Lawn Mower engine not start, starts hard, or fails to keep running?

Several factors can cause this issue. First, ensure the fuel tank isn't empty by filling it. If your model has a choke, make sure it's on. A dirty air cleaner can also be the culprit, so clean or replace it. Check that the spark-plug wire(s) is securely connected to the spark plug. Inspect the spark plug(s) for pitting, fouling, or incorrect gap, and replace if necessary. Other potential causes include a dirty fuel filter (replace it) or low oil level in the crankcase (add oil).
