I found this on the desk of a long time Porsche mechanic locally - I may try to borrow it to have it reproduced if there is any interest
Sorry for the blurry iphone pics, but it's a 1974 print of the VW / Porsche MFI adjsutment procedures for techs.

Cool! If you do reproduce it you'll have to decide whether to keep or fix the typo for the plug gap in inches.
Whatever - I've been gapping my plugs near a 1/4" for years now!
Yes, I'd probably fix it :)
