Why won't my Powersmart DB8621C engine start?
- J
  James MarshallJul 27, 2025
  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.

Why does my Powersmart DB8621C have an uneven cut?

  Shawn OrrJul 31, 2025
  An uneven cut with your Powersmart Lawn Mower can occur if: * The grass is excessively high - mow once at a high cutting height, then mow again at the desired height or make a narrower cutting path. * The blade is dull - sharpen or replace the blade.
