Hi all, This is my first post here and I sure hope that you can help me. I have a two year old Stihl MS290. It has had light use, cutting firewood and a little fencing around the ranch. Recently, while cutting up a log, I noticed that it did not have a lot of power. I only had a few cuts to make so I did those and shut the saw down. A short time later, the saw was still warm, I dumped the fuel and added fresh. The saw would start, idle for a few seconds and die. I brought it home and it has never run since. In fact it doesn't even try, no pops or sputters at all. I have cleaned the air filter, checked the spark arrester screen and found it to be clear, replaced the fuel filter and the spark plug and replaced the fuel. None of this has helped. Is there something simple that I can try before attempting to rebuild the carb or paying the dealer to do it? By the way, how difficult is it to rebuild a carb on these things?
