Pinion angle question

If he wants to compare to the original (and he said he did) He'd need the perches dead level to measure the pinion angle.......but he's makin this way too hard. 5* pinion up (down doing it like Cass said) and he's spot on. That's the right way to do it and too many people have muddied the waters on this thread and made him scared.

I get what you're saying, but nothing needs to be level. It just makes the math easier. 1 and 6 is the same as 'level' and 5.
