    My Echo CS-400 has what is called the i30 Starting System. I have not been able to find any technical description anywhere as to what exactly this is. I don't know if it is an automatic compression release, or automatic ignition timing retarding, or what, but whatever it is, it works. It pulls very easily for a 40cc engine and always starts right up. Does anyone know just exactly what the i30 Starting System is?

    The main feature is a secondary helper spring that is wound as you pull, and at a certain tension point, this secondary spring "releases", aiding in turning the engine over. Most of the Echo engines now have digitally controlled ignitions that automatically adjust timing depending on the engine RPM.

    Sounds similar to a Husqvarna/Poulan system that is installed but not advertised in most cases. Craftsman called it "Sim-Pull" if I remember correctly.

    Thanks, Edge. That makes sense. It explains why a slow pull can start the engine.
