Starting Kick/pull back?

If there is compression release on it it will be in front of the spark plug. Push it down to release compression. If it doesn't have one then pull out the spark plug and shine a light in the hole and look around for carbon build up on top of the piston that would be hitting the top of the cylinder. This will cause to much compression and cause the kick back. If you find a lot of carbon build up on the piston then you need to get some Stihl de-carbonizer and use it as directed. If the saw doesn't run good when you start(before all of this) it then you might have a sheared or partially sheared key on the flywheel side.
