What do you guys do?, take it to the dealer, do it yourself, by ear or with a tach? Now that it is broken in, I took the saw back to the dealertoday to get him to check the carb and set it. First thing he says when he takes it out of the case is "why do you have the bar on upside down?" I'm thinking Oh great, THIS guy is going to set the carb! "You only flip the bar when you sharpen the chain" he says. Then I explain to him that the saw has about 8-10hrs of use on it (hence why I am here) and that I have touched up the chain half a dozen times, I had it apart to clean it anyways, so I flipped the bar. He looks at me like I'm nuts, then disappears into the shop with the saw. He's back in a minute with the saw and says he leaned out the low screw a little bit and that it was good. I asked him if he put it on a tach and he said "it's good" Now I'm a little picky about my stuff, but the reason I bought the saw there is because they are whats called a STIHL RETAIL READINESS DEALER which means they carry the full Stihl line plus the techs receive training annually from Stihl. My understanding is that the saw must be warmed up first, then held Wide Open Throttle for a couple of seconds to see what the max RPM's are. He just bliped the throttle 10-15 times. I also thought the adjust of one screw was dependant on the others. Who knows, maybe it's the OCD but I like knowing that stuff is done right, especially with expensive equipment. I think I will have to learn to adjust the carb myself.
