The first thing you need to do is get a high speed needle valve to turn into the neelde valve body. Both pictures show that it is missing from the carb. It turns onto the exposed threads and is held in position by the clip from turning on it's own. With the needle missing it draws air through the inside of the tube that the needle screws into causing the engine to run way too lean at any setting above idle.
