This is a Genuine Stihl 031 AV Chainsaw with 18" Bar and Chain. This saw has all original parts. Look at the pic with the original air filter. Very few hours. No issues with this saw what so ever. Coil has good fire, Compression is 175lbs. I have not tried to start this. I felt that if someone wanted this saw they could go through it and check it out. The gas was just stale in it, no hardening or varnish look. I personally have been doing this for 20yrs plus and have never had an 031AV in this condition. This will come with a-new Service and Parts Manual. This will be shipped Same Day or within 24hrs of purchase.
