I took my lawn tractor out for the last mow of the season, and wouldn't you know it? After about three minutes, it stalled suddenly and spewed out a big cloud of blue/gray smoke. I pushed it back around to the garage, looked around the engine for anything unusual and decided to try it again. (This all took about ten minutes, and therefore it probably cooled a little bit). It started, but ran kind of rough, and I think there was slightly more smoke than usual. Then, again after about
2 minutes, it suddenly stalled again with a cloud of smoke. The engine is a 5 yr old Briggs and Stratton, model 287707. I went to check/change the oil, and over 1/2 gallon of oil/gas mix (mostly gas) came out. Somehow the gas is leaking into the oil reservior. What has happened? What do I need to check?- posted
