Has anyone seen a Ruixing carb on any husqvarna saws? I was working on a blower and saw it had a Ruixing carb, typically found on cheap and nasty homelite / ryobi equipment. I asked around to see if someone had put it on after sale, but it was an as new machine. I found out it’s sold with the machine like that from factory, is this the same for their saws?
