How to fix Briggs & Stratton engine?
An engine that wont run is not getting one or more of the three things it needs; gas air and a spark. If yours is running with starter fluid, that means air and spark are probably not your problem. If you know the gas is good and the line is clear, that points to a problem with the carburetor. You can clean it yourself if you take your time and don’t lose any tiny parts. Carb cleaner spray is available at any auto parts place.
