carb/idle

well I dont know what carb you have but will try to help. If it is a holley, they are on the side of the metering block. towards the front and on each side of the carb. the metering block is located behind the fuel bowl and in front of the main body of the carb, the screws are fairly small and as is common to most carbs, clockwise is lean and counterclockwise is rich. Most other types and makes of carbs, the metering screws are in the front of the carb down low on the base plate. Some times they are very apparantly located and sometimes you got to look close to see them but usually not too hard. All this info goes out the window if this is a slant six were talkin about here cause they have one barrels and the mixture screw location varies a bit. Its still down low on the bas of the carb but maybe in a different orientation than to the fron of the vehicle.
