Just purchased a 1987 312-8 I'm thinkin in pretty good shape--got a lil rattlin when clutch is out--kinda like an old Harley panhead I had--should I be concened--I'm thinkin not--this is a real informative site--bein kinda cyber dumb, I'm gonna do my best to learn what I can. Would like to confirm year--pix of model #'s included. 12 hp Kohler Magnum runs great. Any advice/help appreciated
