Why is the primary pickup setting on the mercury 650 1972 different than all of the other years? The reason I ask, is because my carbs are off of a '74. After setting the link and sync to near perfect with the primary pickup at 0-2, my idle timing turns out to be around 5 degrees btdc, and my idle lever causes the carbs secondary pickup to engage. I figure that if I start with the pickup at 3-5, my idle lever won't cause the carbs to hit their secondary pickup, and I would start off at a good timing with little adjustment needed on the idle stop screw.
Thoughts?
