The way I see it is that "original" is nigh on impossible. So there will always be something not quite right. And if it is quite right, then I will bet you your Sports 850 that the "original" did not leave the factory that way when you take into account batch differences in parts, continuous design improvement, relaxed production scheduling methods etc. What is original on car A is just a replacement part on car B.
All parts wear/perish/age especially on 40+ year old 850s. If it runs then it won't have the original fuel in it now will it??? Because you can't even get the correct replacement fuel

Then there is points, plugs etc.
Original "appearance" is a different thing altogether, easier to achieve and a lot less anoraky (is that a word?). What about common period modifications, or ones 10 years after the "original" came off the production line?
I just say have fun with it!
