Echo cs 8000/800p/qv-8000 had a production run from 1985 to 2020. Last of the new but discontinued 800p's sold in early 2022.
Over 35 years, no recalls or flaws or serious problems. Quite an accomplishment. At roughly 16 lbs, 1.5 lbs lighter than a new 585 husq. I've heard folks claim they're heavy, but I think the weight is appropriate. Perfect balance with a solid 28" bar.
The press-fit metal oiler gears on the 8000/800p never strip, like the plastic ones on other saws. They'll over-oil a 36" bar. I like the manual oiler for instantly freeing up a frozen, below zero bar at start-up. Finger adjustable idle is pretty sweet, I always seem to use it. No decomp bllsht and a nice d-handle on the qv models.
Unlimited ignition coils and no carb governor bllsht like some of the 81 cc husq saws.
Fire departments all over the country used them as a qv-8000 (quick-vent) saws with carbide chain on a special downward-pointed bar.
The qv surplus saws are a good way to get into 81 cc's of muscle saw for cheap. But cutting into asphalt and metal roofs shows unique damage to these saws that you may not ever have seen:
Flame damage to air intake. Bits of metal and abrasive shingle remnants vibrating around the flywheel and rubber lines causing pinholes in rubber lines. Excessive vibration rattling screws loose. Excessive abrasion to the entire exterior.
I'm porting one right now. I've seen them sell for $225-$400.
Converting to a regular chainsaw:
The steel armor plate uses long screws. Those 3 screws will need to be replaced with shorter ones.
A set of felling dogs+hardware will need to be ordered.
