Pulling V.A at idle

And the primary picture was with the blades all the way closed. They are a little more the square. I would square them up and crack the secondaries just a LITTLE. Dont crack them enough to expose any of the t slots. Just a little.
Ok cool. But would the main idle on the throttle level affect the t-slot on the primary? And No Sir, no finger on the primary pic. Should I close the main idle screw ?
