I found a Stihl BG-85 gas leaf blower while I was out on a run. It was in the ditch, so you really couldn't see it from the road if you were in a car. I left it there for 3 days, in case the owners came back for it. Since it was still there when i ran by three days later, I came back with my car
A new spark plug, air filter and a tube/nozzle (free from the dealer, Thanks Guys) and it's been cleaning my driveway for years.
