A friend of mine just bought a Stihl MS391 to replace his 1979 Stihl 041AV. Long story short - I am considering purchasing his 041AV. My primary saw is a MS260 with an 18" bar. I use the MS260 on about everything but I have an older Big Blue Homelite for larger cuts I would like to replace. Can you guys help me with a couple questions? 1 - How much would the 041AV be worth? It has been well taken care of and is in great condition, but the bar has a fair amount of wear. It is a 20" bar. 2 - If I replace the bar - how large of a bar could the 041AV handle? The specs state teh saw is around 61cc. I would like to get at min a 22" bar if possible. I figure no sense having my "larger" saw have only 2" more bar than my primary saw. But at the same time I don't want to underpower a longer bar. Any advice would be appreciated - thanks!
