how can i fix my bolens BL100 31cc weed trimmer?

I have a yellow, Bolens BL100 31cc weed trimmer and the pull string broke. When i went to fish the string back through the hole, the winding spring came out. i winded it back up and put it all back together and for some reason the clutch seems to not be working right. when i pull the string to start it up, the head spins too and with full force. i dont see the clutch anywhere from trhe starter,and forward. is it something i did? isnt the clutch behind the flyweel? i never saw one and this is really frustrating me..someone please help
