Holley 1850 fuel transfer tube seals??

When you reinstall the needle & seat assemblies lube the o rings, then screw them in deep enough that the nut barely has anything to grab... That way when you start the engine you'll know the fuel level should be low.... So, with the sight plug out and a screwdriver & 5/8 wrench you can slowly raise the level... If your careful you can do it with the engine running, back the lock screw off slightly so fuel weeps but not so much that it becomes a serious leak... Turn the nut one flat & snug the screw... Let the fuel level stabilize... Repeat till the fuel level is at the point it just trickles from the sight plug hole....
Thankyou, i did watch several videos on this, a couple were from a Holley executive, but what I understand is that the start point is to set them static with the bowl inverted and the float level with the bottom, ( well top actually as it's upside down at this point ) of the bowl, which is what I have done however if I understand you correctly you are suggesting otherwise, doing it your way will there be enough fuel in the bowls for the engine to start and run while I do the adjustment?
