A big part of that is the condition, but here is a link to a thread here on the forum with a 090 that was sold last year. Another thing too with the forums here, typically you cannot sell anything until you have made at least 10 posts (gives people a chance to get to know you), since you are few months from getting any pictures posted, have a look around the forum and interact, that way if you do decide to list your saw here, you will be able to put the big shiny "SELLING" tag on your post and get lots more attention that way.
I have decided to sell my nice all original 090 with the 41” West German bar, looked all over and it’s so hard to get a good value and although eBay isn’t the best place to look I don’t have much choice but to look there for comparisons. This saw will be shipped in two packages saw in one and bar/chain in another the bucking spike won’t be coming with its for an early contra project I have. Also needs the new choke rod assembly that’s 9$ on eBay for an oem one no idea what happed to original. This saw runs as good as it looks asking price is 2000$ plus shipping o.b.o.
