To fix a flooded Stihl chainsaw, first, turn off the chainsaw and remove the spark plug. Dry the spark plug thoroughly. Next, set the chainsaw to the 'run' position, and pull the starter rope 6 to 8 times to clear out excess fuel. After this, reinsert the spark plug, and attempt to start the chainsaw again. If it doesn’t start on the first few tries, repeat the process. Remember to also check the air filter to ensure it's not soaked with fuel as it may need drying or replacing.

FAQs & Answers

  1. What causes a Stihl chainsaw to flood? A Stihl chainsaw floods when excess fuel enters the combustion chamber, often due to repeated pulls on the starter rope without the engine igniting or a clogged carburetor.
  2. How do you dry a flooded chainsaw spark plug? Remove the spark plug from the chainsaw and wipe it dry using a clean cloth. Allow it to air dry completely before reinserting it to prevent further flooding.
  3. How many times should you pull the starter rope to clear a flooded chainsaw? Pull the starter rope 6 to 8 times with the spark plug removed and the chainsaw set to the 'run' position to clear out excess fuel.
  4. What should I check if my Stihl chainsaw still won't start after clearing a flood? If your chainsaw doesn’t start after clearing a flood, check the air filter for fuel saturation and dry or replace it as needed. Also, inspect the spark plug and carburetor functioning.
