The engine should idle smoothly at 350 to 400 RPM.


When your engine is idling with the choke fully open and the hand throttle cable in the off position, the idle speed screw should be resting on something, usually a fast idle cam. At idle with the choke wide open, the screw should rest on the lowest step or lowest portion of the fast idle cam.

With the engine off, moving the choke plate by hand should cause the fast ilde cam to move.

Your idle speed screw doesn't appear to be in contact with anything in the photo.
