Removed the carburetor, gave it a good cleaning, replaced the adjusting needle and jet and all the gaskets and seals. Now it starts and runs like a champ. by the way, I bought this mower back in 1968. It's a riding mower with a 5hp Brigs and Stratton engine. They just don't make them like they used to.
