To be fair, the YouTuber DID know exactly what was wrong (he successfully troubleshooted the problem, and really didn't need help)...if you watch his video from about the 8 to 11 minute mark, he covers:
- the wrench is defective (and sets the timing wrong)

- how to set timing the Ford way (from Victor Page's Blue Book, pages 310-312)


If one were to just watch just those three minutes, and skip the first eight minutes, then all the pertinent information is covered.
