Stihl 012 carburetor issues

[Wood Doctor]

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.

My 009l has a little rubber guide for carb adjustments

Those rubber guides wear out and some owners just throw them away in frustration.One thing for sure, thus saw is a noisy barker. I would have sworn the last one I serviced was running straight pipe without a muffler.
