When you pull the rope and it feels like theres no tension on it, you need to determine if it is the rope assembly not catching all the time. You can do this by removing the spark plug and holding your finger over the hole and see if there is any compression. If the rope assembly is not catching all the time it can cause it not to start if your not getting a full pull on it. If the rope assembly is catching good and you may have a compression problem, like a valve sticking open on it, this will make the rope fell like there is no tension on it also.
