Is this saw worth trying to fix? I just moved into a house with a few acres of thick woods. I was planning on buying a new chainsaw, but... I was cleaning out a shed in the back when i found a stihl 038AV. I have no idea how old it might be. It has a broken recoil. I took the recoil cover off and the spark plug out and was able to turn it over. I have also been able to determine that it has spark and compression. should i go further??? how old is it??? I know very little about chainsaws, please advise.
