To all.. I rag on this at least once a yr..Cranked up my 1650 after sitting outside for 3 weeks..By the time I got to the garage it was rolling smoke from engine.Scared the heck out of me you can bet!!Then came the unmistakeable aroma of burning mouse residue...Ended up removing all the muffler surround to get to a pile of smoldering grass and paper.Every yr 1000's of fires are caused by leaf and grass residue placed graciously by mice..don't put them away without cleaning them off .If there is a way a mouse will build....All kinds of warnings are coming out about new battery powered machines..
