When adjusting the carb, when you turn the needle in it leans the mixture and out richens it. As far a fuel in the carbs throat it is normal but it should not be runing out of the throat either

if per chance you are indeed refering to fuel running out of the thoat (front) of the carb, my main suspects would be the needles and seats getting old. simple procedure to replace, and the parts are cheap.
