I have a C/Cadet XT1 LT46. I think it's a 22 HP Kohler. In order to start the mower, I need to push up on the choke lever momentarily and it will start right up. I'm assuming that there was a linkage or spring that came off. Can someone confirm this for me? How and to where does the linkage attach? If anyone has a part number and/or photo of how it attaches, that would be great. I'm sure I can fabricate one if need be but need some direction on where it attaches. Thanks so much!
