45 degrees initial will kick back hard enough to damage the starter. I still think you are reading something wrong.

If you are 45*, you are exactly 1 cylinder number of degrees off (360/8 = 45). FO is 1-5-4-2-6-3-7-8

Guys, Birdland posted this about seven months ago (five posts over two days) and has not been back since. I doubt seriously that we'll see any response from him at this point. Just my thoughts, not saying don't reply...
