Hi, I picked up two of these and I'm fixing them up to sell. Sometimes when I put the stater rope, it feels like the is nothing there!? If I pull it gently a few times it seems to eventually catch the pawls? Any idea what could be causing this. I doubt that I can easily find parts for this. I also noticed the coil system is kind of strange on this saw. Works fine, starts and runs but I can't figure out where the contacts are. Thanks for your help, especially with the starter rope recoil issue
