Saw a add here in our local small town paper. Guy has a Stihl Farm Boss 290 for sale, only $100. Sounds like a good deal so I called him. He told me that the saw was less than a year old and was in like new condition, BUT, he loaned it to his brother in law and the saw was serviced with straight gas. So the engine is locked up .. It'll take a new cylinder, piston, rings and who knows what else. So I passed, Did I do right by not taking a project like this.? Probably take some money and effort to bring back from the dead. David
