Hi, there everyone. I'm new on here and own a 1969 Cub Cadet 124. I've had some issues deciphering the serial number of the K301A (Kohler) motor on it. The serial number is E0022933. All literature I've seen regarding these serial numbers state that the "E" should be followed by 6 digits, not 7. Also, that the first two digits should be between 10-19. Anyone know anything about this? Appreciate any info possible.
