Depending on the engine there should be either 3 or 4 adjustment screws.
If you have a 2 needle carb then you'll have a Low speed needle (either on the throttle arm, or the opposite side of the throttle arm), a High speed needle (should sit right above where the fuel enters the carb), and the Idle Adjustment screw. This is generally the smallest diameter needle on the carb and is gnerally on the carb body. The idle adjustment screw is a small screw that stops the carb from closing completely when you hit the brakes or let go of the trigger.
If you have a 3 needle carb the idle screw is still generally the smallest diameter screw and will usually sit on the carb body.
