Roger this is simply over carb base angle words which I don't believe Richard even pushed-
I believe he referenced that phrase as an initial get close starting point as he then wrote about using the bubble angle finder against the crank pulley---and about the same as Inland Empire did with putting it on the starter mounting area( only works gm ) You and I are the ones who have continued this and it seems to me that you are more inclined to push carb angle being a huge factor in a build than the proper establishment of driveline angles----------


Using the issue of carb base angle as the go to prime issue is about like going with windshield wiper mounting as the second item on the build list--------
