Option 1 allows for the inner idle needle to be adjusted and a white plastic cap placed on top to hide the needle. Option 2 is with the same inner idle needle but also has a black idle screw located above the needle for a fine-tune adjustment.

Please read the following instructions for correct adjustment of the WY J at the idle position. Remove the plastic plug located directly above the inner idle needle. Using a 2. Turn inner idle needle clockwise turns very slowly. Start engine. With the engine in the idle position, continue turning the inner idle needle clockwise.

Turn inner idle needle counterclockWise rich until optimum idle is obtained. Please note that carburetors and engine applications will vary, therefore the needle setting may vary also. Adjust the idle speed screw to the correct idle RPM. Check idle, progression and wide-open throttle. Reinstall the white plastic plug. Start engine and place throttle in tile idle position.
