Why my Toro 74311TE Lawn Mower engine does not start, starts hard, or fails to keep running?

There are several reasons why your Toro Lawn Mower engine might not start, starts hard, or fails to keep running. First, check if the fuel tank is empty and fill it if necessary. Also, ensure the oil level in the crankcase is adequate and add oil if it's low. Make sure the throttle control is midway between the Slow and Fast positions, and the choke is in the closed/on position for a cold engine or the open/off position for a warm engine. Other potential causes include a dirty fuel filter (replace it), a dirty air cleaner (clean or replace it), corroded or loose electrical connections (check and clean them), a fouled or improperly gapped spark plug (adjust or replace it), or a disconnected spark-plug wire (check the connection).
