The 209 spring should be slack when the speed control is in the idle position, because then the engine speed is being controlled by the 211 spring. At any higher speed than that, the speed must be controlled by the 209 spring. If it is being controlled by the 211 spring, or not being controlled at all, with the speed control above idle, something is wrong with the linkage set-up. A series of pictures of the linkage at various speed settings should help us get to the bottom of the problem.
