That is an oldie! If your serial number is correct, that is a 1948 model 14. That is the first year they were made. It was made in July or August and the first one was made in March. They were first listed as 5hp. Later the listing was changed to 5 1/2, then 5 3/4 and finally 6hp. The 6hp model 14 was discontinued in 1966. They are a real challenge to find parts for, but searspartsdirect can still find parts.
