does the engine have a carburetor or is it fuel injected? A carbed engine has mixture screws along with a base idle screw, a fuel injected engine the idle is computer controlled.
With the engine running, turn the idle screw until you get the speed you want.
At the base of the carburetor are 2 screws. One adjusts the idle speed and the other adjusts the idle mixture. Screw the idle mixture in until the engine starts missing then screw it out 1 turn. Then, adjust the idle speed screw to about 850 RPM.
there is an Allen screw and a nut on the throttle cable you loosen the nut and the screw and adjust it to make it idle up or down.
Set idle speed to proper r.p.m, by adjusting the IDLE SPEED SCREW. Turn the IDLE MIXTURE SCREW or the AIR SCREW to for correct procedure, achieve highest speed and best response. The IDLE MIXTURE SCREW (FCR) controls fuel delivery to the idle port and the SCREW is located on the engine side of the carburetor slide. Turning the IDLE MIXTURE SCREW out will make idle and off-idle richer. Turning IDLE MIXTURE SCREW (CR, PWK, PJ, PE) controls the amount of air to the IDLE and SLOW CIRCUIT. This SCREW is located on the air cleaner side of the throttle slide and turning the SCREW out will lean the mixture and turning the SCREW in (clockwise) will richen the mixture.
