I am retired and been buy things that no longer run, fix them and resell, sometimes. I have 5 Stihl chainsaws, 021, 026, 031AV, MS360 Pro, 440 Magnum and a HT 56 C limb saw. Every time I Google to find chainsaw info, the Arborist forum pops up and I usually fine the info I am in need of. So thank in advance. - Rick
