carb help

yes its is a carter that is on it, I will probably get the same one from Napa auto parts. I wish I knew someone around here that could help me in person, everyone i know thinks they know how to work on cars but can't, also I have hardly any tools living in an apt on a hill prevents me from doing more. Do I need a dwell gage to adjust? I tired the whole in find the middle point but it seems the carbs i had ran same no matter how much you turned the mixture screws. seems like I can fix everything else on the car but the carb.
