Weber DGV float setting

awesome PDFs for the 'ol Weber. Ill assume the (new) 18mm clearance is accurate for new style gasket and new floats per Redline as they probably sell the most WEBER cast carbs here in USA. I can get that measurement at the tip of the float. When they show it parallel to the top is were I lose it as it cant be 18mm AND parallel unless you bend the tab at like a 30 degree angle.
