Holley instructions contradicting on fuel bowl level ??

I went back and forth with the same dilemma many times, without the sight glass adjustment is made up to bottom, with sight glass it is mid point, on my Ultra 670 I am just slightly over half. The float adjustment screws sound like their out from each other, there should be screw slots once you take the cap off that is in the top of the needle. One thing I had to do was after adjusting was to drive and burn the fuel out of the bowl, there was a process I found that described how to do it without driving but I never could make it work, the rear bowl would not dump at all and the front didn't dump as much, set them close as you can with each other to about mid way, take it for a drive and carry the tools to adjust on the road. another thing, it looks like your missing a nut on the needle, called the adjusting nut, Im guessing your starving for fuel
