Stihl chain saws have a choke that makes cold starting easier, but you have to use it properly. If the engine doesn’t start on the first three or four pulls, the fuel and air mixture becomes fuel rich, and if you continue to pull the starter while the choke is closed, there is too much fuel to ignite and the engine floods. You can simply wait for the fuel to drain, but there is a faster way to clear the engine.
