  Shawn SimonAug 12, 2025
  If your White Outdoor Lawn Mower engine won't start, several factors could be the cause. First, make sure that the blade control handle is engaged. Next, check that the spark plug wire is connected securely to the spark plug. Also, ensure that the fuel tank isn't empty and that you're using clean, fresh gasoline. If the engine is flooded, wait a few minutes before attempting to restart it, and avoid priming it this time. Other potential issues include a faulty spark plug (clean, adjust the gap, or replace it) or a blocked fuel line (clean the fuel line). For priming issues, consult your engine manual.
