I just inherited a 12.5 Horse Kawasaki powered John Deer tractor that is about 10 years old. It has been sitting in a barn for a while. I cleaned the carb changed the oil and battery and got it running. The motor runs fine in neutral but as soon as I put a load on it whether it be putting the blades in gear, Putting it in FWD or Reverse- It instantly Dies. Anyone have any ideas? I can get the RPMS up pretty high before the choke kicks in and it sounds pretty strong until a load is put on the motor.
