  There are several reasons why your Powersmart Lawn Mower engine might fail to start: * The engine start/stop lever may be disengaged - engage it. * The spark plug wire may be disconnected - connect it. * The fuel tank may be empty or contain stale fuel - fill it with clean, fresh gasoline. * The engine may not be primed - press the primer bulb. * The spark plug may be faulty - clean, adjust the gap, or replace it. * The fuel line may be blocked - clean the fuel line. * The engine may be flooded - wait a few minutes to restart, without priming.
