On pulling the starter cord, there is a rattling noise as if a nut has come loose. The motor does not kick over.
When you pull the starter cord, three things are happening inside;
The cord is spinning the spool that it is wound on, the spool has a gear or molded teeth which engage the motor through spring-loaded levers, and a coil spring returns the spool to it's original position...hence the name "recoil" starter.
The first possibility is that the gear has come loose (if a mounted gear) or broken (if molded to the spool), and the rattling is the loose part(s) flopping around instead of engaging the motor.
The second possibility is that the lever springs are a bit dirty/rusty or bent and stuck out of position, and the gear/teeth of the spool are just banging across them instead of engaging.
Start by removing the plastic cover(s) to gain access to the starter rope's origins, ie; the spool and the starter levers.
The recoil spool with sping are likely attatched to the cover as a unit, so you don't have to go any deeper into the recoil.
Check the drive gear/teeth for a solid mount and teeth damage (they are saw-tooth shaped), then check the 2 small levers mounted to the crank for free swing and solid springs...a drop of oil or WD40 at their mounts won't hurt, just wipe the excess and while you're there, clean the magneto face and the magnets on the crank with a little WD40 on a rag.
* Don't despair if they look fine...it's entirely possible that they were stuck out of position until you pulled the recoil, and a decent cleaning will keep it from happening again.
