not 100% original, has a newer replacement OEM recoil cover, newer top cover and badge, new fuel cap (these sometimes leak as they are not a perfect match for the flat caps in all cases)
suspect AM replacement top handle as well
A real nice example might bring $800 retail but the sell around here for @600-650 in nice solid running condition with a 28-32" b/c. I have several that wouldn't be for sale at any price and a true NOS example would easily bring upwards of $1000.
the single, distant, blurry pic isn't a great tool for determining value.
If I was buying to flip I would be at $400.00.
If I was buying to cut wood, I would check the piston and offer as much as $600 if that is what it took and the saw looked and sounded good in person.
If I was buying to have it ported I would figure $950.00 total budget and back down to my offer based on what it really needs to be as nice as you want it.
I would switch to HD air filter setup immediately unless flipping.
