Then, turn the screw counterclockwise 1-1/2 turns. Locate the idle mixture screw and turn it clockwise until the needle lightly touches the seat.With the engine off, remove the air filter and air cartridge.If your carburettor contains these screws, proceed below. Check for an idle speed screw designed to keep the throttle plate from closing completely, and an idle mixture screw that limits the flow of fuel at idle. On some float-type carburettors, you can adjust the air-fuel mixture and engine speed at idle. If it fires only a few times and then quits, assume a dry plug condition and consider the causes of a dry plug, listed in Step 5. Screw the spark plug back in and start the engine.
