STEP 11: Be sure the Idle Valve Adjustment screw (gold colored slot head) is turned clock-wise until it bottoms out. Do not use too much force when bottoming out.

STEP 12: Start the engine, if no idle can be achieved, turn the gold colored idle valve screw counter clock-wise in small increments, restarting the engine until desired idle is achieved.
