220 views

A chainsaw floods when too much fuel enters the engine cylinder or carburetor. This can happen for several reasons: 1. A choked engine not started correctly (using the choke too much or too long), 2. Leaving the chainsaw on its side (which can cause fuel to flood the carburetor), and 3. Poor starting technique, such as pressing the throttle while trying to start it. To prevent flooding, follow the manufacturer's starting procedures carefully and avoid overusing the choke.
