Okay, hello, welcome to the forum. You got yourself a good engine, and yours looks in alot better condition than some of the ones I have made run. I am not good at decoding those ID tags but I believe from past experience it is a 1982 or 1983 and older up to...(I can't remember that exact year). Anyway, as for tune up info, does it run now? If not does it have spark? Are any parts missing? Answer these questions and it will be easier to help you find parts, heck maybe you don't even need any.
