There seems to be a digit missing from the Code, rayman. If you correct that I can tell you the engine's date of manufacture. Meanwhile here is the Illustrated Parts List:

At this point I think we need clarification that the control in the picture is the same as yours, plus we need a picture of yours, and clarification of your exact question. As you can see, there are three things to connect to the throttle butterfly lever. At the long end of the lever, the main link (from the top of the governor control) is connected. In the middle, the anti-oscillation spring goes through the tiny hole. (Note that the anti-oscillation spring is slid over the outside of the main link). At the short end of the lever, the remaining link (from the middle of the governor control) connects.
