Two questions. I have a JD314 with the Kohler 321. First question is what is the overall length of the spring? Mine measures 8" and doesn't hook up correctly but it wasn't when I bought the tractor either It was hooked over the edge of the throttle lever . Second question is what holes should the initial starting place be. I took pictures when I took it apart but I lost all my pictures on my computer. Thanks for any help .
