Unfortunately this is not a problem unique to Stihl.I do not have all of the current line up of Stihl chainsaws. I was sold a bill of goods that a MS 661 could handle any thing but turned out to be junk. It has some engine monitoring system that does not work. I would have to carry around two MS 661 to just to keep one running. I can not afford to have a saw quit for any reason. With my 056's all I have to have is a spare ignition, carburetor, and oil pump. When the carb on the 661 got plugged I nearly crushed it with my splitter. I am thinking about parting it out and trying to get some money back out of it. The 070 cuts circles around the 661. The 070 has a slower chain speed that allows for more cutting less sharpening. The 070 is too heavy to climb with though. Climbing is not some thing I do much of any more. That is one example of Stihl being junk. For those who are happy with the Stihl products that is their choice and for many upon many are happy with their Stihl products. New Stihl technology does not work for me as I need absolute reliability. Thanks
It is also the reason I grabbed a 461 last year. Not that the 462 is a bad saw and I'm sure the 500i will be great, but it's tough to beat the simplicity of a good carbed saw.
