Also: In most pictures of the throttle [like in that one, not mine], the three tabs on the pot are facing upward, away from the slider. (Which seems to be the correct way how a pot is manufactured).
In my case, these three tabs were bent (or assembled to the part) the wrong way, facing down (!) with the tabs and then the wires awfully close to the slider. Of course this could spell troubles since the slider would constantly touch the wires and this can cause all kinds of problems of course.
