A friend brought me his Stihl ms 180c with the complaint that it would not rev up. This saw is used as a weekend home owner. After checking the muffler for carbon, and found none. Next removed carburator and checked the metering lever which is level. the diaphram. The saw is still running too rich to rev up to its potental. The fuel line and filter looked ok with no sign of any leaks. Also the piston does not have any scratching. I'm puzzled as to what could be causing the overly rich fuel mixture, that is not allowing this saw to rev up. the muffler is also wet after running the saw. Normally the ms 180 has bog problems and not getting enough fuel. This saw is getting too much.What are the options, as I'am puzzled by this.
