How to Crank a Flooded Chainsaw

When too much fuel enters the carburetor and combustion chamber of a chainsaw during starting, the engine will flood. After fuel is sucked into the combustion chamber, getting the combustion process started and the chainsaw running is difficult. The combustion chamber needs enough air in the cylinder for the fuel to ignite. This problem can occur often, especially if the choke was left open while starting the chainsaw, but it won't damage the engine or carburetor.
