Why Powersmart DB7651-24 engine fails to start when it cranks over?

Several factors can cause this. The engine ignition switch might be in the OFF position, so ensure it's set to ON. The spark plug wire could be disconnected; make sure it's connected to the spark plug. A faulty spark plug might also be the culprit; clean, adjust the gap, or replace it. The engine might be flooded with fuel, so discontinue choke or primer use, and clean or replace the spark plug. Ensure the safety key is fully inserted into the ignition. Also, check that the choke is in the START position, and if not, move it accordingly. Other potential causes include the engine not being primed with fuel, incorrect or stale fuel, a blocked fuel system, or the fuel shut-off valve being in the OFF position. Address these points to troubleshoot the issue.
