You can change the spring location on either end, the governor side and the cable side. I would set it up to the book setting first Doug, then adjust it once you get it running. I know on some of my JD's, I have way more throw on my throttle lever than is on the governor, sometimes I even get the same on the choke side. Setting a Kohler up from the beginning is a bit of process, but once you get it dialed in you'll have a nice little powerhouse. Two upgrades I would suggest, a epoxy filled coil and a Kirk's Transdensor II. The oil filled coils can heat up and vibration tends to make them fail or act up. The Transdensor II gives you a better spark and drops the voltage going through the points, making the points last longer.
