Engine that Will Not Start

• 1). Check to see if the switch is set to the "On" button. Many times gardeners will confuse "Off" with "On." Keep your manual on hand to identify parts.
  
  
• 2). Look at the spark plug to see if it has eroded or wet. The spark plug is located down the center insulator. If the spark plug is wet, replace the spark plug with one from a local hardware store or your weed trimmer manufacturer.
  
  
• 3). Examine the fuel supply. Weed trimmers should be drained of fuel at the end of the growing season. Replace the fuel in the spring. Fill your weed trimmer with a fuel stabilizer to keep it running smoothly through the season.
  
  
• 4). Start the engine and check if you smell fuel. A fuel smell emanating from the weed trimmer indicates that the engine has flooded. Set the weed trimmer down for 10 to 15 minutes before trying again. Take the weed trimmer to its manufacturer if the equipment continues to flood.
  
  

Rusted Weed Trimmer

• 1). Wash off the weed trimmer with a garden hose. Mix up one part liquid detergent and nine parts water in a bucket.
  
  
• 2). Scrub the weed trimmer with a metal brush to remove rust. Rinse off the weed trimmer and dry.
  
  
• 3). Sand the weed trimmer with a piece of 80-grit sandpaper. Wipe off the weed trimmer with a towel.
  
  
• 4). Pour two parts motor oil and one part kerosene on a rag. Rub the weed trimmer's blades with the mixture to prevent future rusting.
