How to Clean a Chainsaw Spark Plug

Spark plugs are completely indispensible for your chainsaw engine; but they often get clogged with dirt, oil and grime, causing them to stop working properly.

If your chainsaw’s spark plugs get dirty with use, it is time to purchase a new one. Or better yet, save some money by cleaning the old one.

Though it sounds like a hard job, with a few simple instructions, you can clean your spark plug, making it look and work like brand new.

  • Get your safety gears on, including safety glasses and gloves.
  • If you are about to remove all the spark plugs at the same time, it may be a good idea to label and number down each wire so you can remember ‘what goes where’ afterwards.
  • Use a clean cloth or brush to remove any visible or large debris from the spark plugs.
  • For cleaning the firing end of the plug, you can use a quick drying liquid, like 90% strength alcohol or carburetor cleaner or mineral spirit.
  • If the spark plugs are badly fouled, try dripping them in ? inch of toilet bowl cleaner. Brush or dig out any dirt using a thin wire.
  • Dry well.
  • With an air compressor, blow away any excessive dirt particles from the spark particle. If you don’t have a air compressor, canned pressurized air works good too.
  • Even if the spark plugs appear to be clean, apply a dry compound to it to remove any excess dirt.
  • Use the air compressor again to blow any remaining debris.
  • Clean the threads of the spark plug with a clean brush.
  • Use a rag to clean the holes of the spark plug. If they are too dirty, use the same solution and dry well.
  • Reinstall the spark plugs back into their original holes.

An easy procedure to follow to save a trip to the hardware store and some dollars.
