My father gave me his old Wheel Horse tractor model C-111 that he does not use anymore it sat for many years it's in good shape he took good care of it. The motor ran great when it was put away but back then we were having issues with the carb and it could really use a new one. The motor is an 11 hp B&S does anyone know where I can find a new carb for this? According to B&S they no longer make this motor if the motor dies what can I replace it with?
