Sorry, I let my factory manual go with mine about 7 years ago. I had all the technical updates with mine too. The 74 updated main crankcase upper and lower halves which corrected several oiling problems. Most of these motors blew up before they reached 20k mi. Mine, a 73 never had the factory recall to replace the engine cases and it was still running strong with 68k mi on it when I sold it. Maybe that was because I never let any dealer mechanics near it. I did have a problem with it jumping out of gear when it had low miles on it, I found a small broken spring on the gear changer and replaced it and no more problems.
