If you're having trouble starting the engine, the Stihl operating manual provides several troubleshooting steps on page Particularly several issues can arise when the engine is cold.

For cold engines and very low temperatures, allow the engine to warm up after starting by moving the setting lever to the lower stop as soon as the engine runs, and opening the throttle slightly. This will allow the engine to idle and warm up for a short period. If the engine does not start at all, it may be because you did not turn the choke knob to open quickly enough for a cold engine.

In this case, the combustion chamber can flood. To address this, pull off the spark plug boot and unscrew and dry off the spark plug. Set the stop switch to 0 and open the throttle fully before pulling the starter rope several times to clear the combustion chamber. Fit and reconnect the spark plug, move the stop switch to the on position, and turn the choke knob to the open, leftmost position even if the engine is cold.
