yep... My buddy at CheapStihlparts used a vertical (the side opens and you put your saws in on racks) hot water part cleaner to clean the most disgusting chainsaws you've ever seen.. Couple of teaspoons of transmission cleaner, insert 3 to 6 entire saws (with ports blocked off) and 10 minutes later they look like new. They come out so hot they air dry in a couple of minutes. If you not tearing them to pieces like he does, start them up to clear out any condensation and now it's pleasure to work on them; well, kind of...
Cost was about $2,000 including freight of about $450... It has an oil skimmer on the side to removed the oil that separates. Very nice unit.. I'll track down the name.
