I don't know why Holley "hides" this info. It's not even included with the electric choke kits!

You're looking for Page 4, figure 15--and also glance at figure 9, page 3. Figure 9 doesn't exactly apply but shows the relationship of the choke blade/air horn, and how to measure the gap.
You'll need a "special tool"--a paper clip with the end bent at a 90* angle.
Also note that you'll want to align the fast idle linkage so that the fast idle cam drops to the second-highest highest step when the choke pulloff pops the choke blade off.
