Adjusting float level on three screw SU's

Played with the float levels tonight. Removing the lid is stupid easy when you rotate it properly as @siteunseen described. 

Instead of going by just measuring the float, I checked it against the fuel level in the nozzle when 2.5 turns down. From my reading the fuel level should be 1/16 below the nozzle when they are 2.5 turns down. Thats where I tried to get it.
