  If your Stihl Saw engine won't start, it might be due to several reasons: * The fuel tank may be empty. In this case, mix the fuel and top up the chainsaw. * The engine may be flooded. If so, vent the combustion chamber. * The carburetor may be too hot. Allow the chainsaw to cool down. If a manual fuel pump is fitted: Press the manual fuel pump at least 10 times before starting the engine. * The carburetor may have iced up. Allow the chainsaw to warm up to +10 °C.
