Not Ranked

I've modified/blueprinted hundreds of holley type carbs for some big cam engines and generally around .105- .110 will get the idle to around 850 with the butterflies adjusted to where the transfer slots are the little perfect squars---Sometimes I take a .025 drill and reverse broack a little exact hole there with the plates just lightly snugged closed---will need about 1 1/4 turns on idle air screws
