Just talked to my service guy about when to expect my Stihl 110 back from him and he said that there is nothing that he can do to fix it. It has now been in the shop for over three months and I bought it one year ago last week.. He told me that he called every Stihl service center around to see if anyone has figured out how to fix it and no one has had any solutions.. One thing he said was one guy explained that the valves needed to be adjusted every 8-10 hours or so... Holy Hell... So pretty much I just spent $350 for nothing except for about four months of use... Does Stihl not have a response to this issue?
