Yep, I still have a 16" bar Mobilco Echo CS601VL. That was a 1970's trade-in, from a farm, where it had been worked hard.
It cut a power of really old, very hard yellow/grey box firewood [ringbarked 50+ years before] for the old man, before he passed it on to me around 1992, when the olds moved to a house without an open fireplace.
It probably needs a kit through the carby, and maybe fuel lines, but it still runs OK. I just don't leave the fuel in it between uses now, due to the properties of modern petrol!
