edelbrock carb question

the main problem that i get with ALL eddy carbs is that the floats are always out of whack. the float drop is supposed to be 15/16" to 1", and its always 1 1/4" to 1 3/8" and that makes a big difference. i have put on so many this year and not one has been correct out of the box. pop the top airhorn off and reset the float drop and float level(7/16").
