I have two running echo 500evl chainsaws with 24" bar. They haven't been used in a couple years. I always stored them and overwintered them properly. Put gas in them a week ago and they both started right up - after 10 pulls or so. One was dropped a few years back and has a broken handle. The throttle and choke and everything still work fine.
Only reason I'm selling is I worked out a deal with a friend who has property to use his equipment in exchange for my labor.
