To unflood a chainsaw, first, turn the chainsaw off and remove the spark plug. Dry the spark plug thoroughly. Then, set the chainsaw to full choke, pulling the starting cord a few times to clear the chamber of excess fuel. Next, reinstall the spark plug and set the chainsaw to the 'start' or 'run' position. Finally, pull the starting cord again. If the chainsaw doesn’t start after a few pulls, repeat the process, ensuring the spark plug is dry, and the fuel has not contaminated the air filter.
