12 hp Briggs and Stratton model # 284707 1025 e1
Hello I have a riding mower with a 12 hp briggs engine. I went to get it started the other day and it would turn over and the starter turns the motor but it wont catch on and run . It sputters for maybe 5 seconds. I cleaned out the carb and the fuel tank. The starter goes ata high speed until it makes a whizzing sound. What could this be?
