Smokin Dodge said the oblong holes are for moving the plate. Yes, I understand and did that. I also noticed the AFC housing cover that is held down by 4 bolts (1 being the breakoff bolt) has oblong holes in it that allow it to slide back and forth about 1/8 inch. Thus you can move the fuel plate and also move the AFC housing cover on top of it. Does sliding the cover have the same affects and to which direction does sliding the cover have what affect?
