Every time I read one of these threads I have to wonder why my 010 is still running today. That carb setup is an engineering nightmare. For example, note where the tank vent goes. Then see how Sthl thought that their buyers should tune the carb by playing blind man's bluff. Add to that the impossible mission needed to rebuild the top end. Then there's the power switch issue, a complete after thought -- a 5" length of copper attached to a slide switch to make contact with the frame? I could go on and on, But heck, guys, this is a classic.
