A person has a Stihl MS460 for sale, says it runs fine but the rubber mount slipped out, needs a new case. Is that a broken case, I can't really see or know enough about a MS 460 nomenclature to know. I have to drive about 60 miles to check out and they said their bottom dollar is $225. Odd amount, but is that a broke case? If runs, are used cases available to repair? Or give $225 and part out, which is not what I prefer, would like to fix and keep, maybe sell. Thoughts?
