engine was smoking added oil unable to get engine to start Update (07/25/2017) engine was smoking added oil still unable to get engine to start.
Was the smoke white before you added the oil? If a lawnmower engine blows white smoke out its exhaust, it means that the engine is burning oil - meaning that there is too much oil in the engine. If you added more oil to your lawnmower after it already had more than enough, you’re in for a bit of trouble.
