I have an older Craftsman rider with a Kohler CV16 motor. The motor was surging a lot last year. When I started it up this year, it was surging and would only run for about a minute then die. I purchased a new spark plug, spark advance module, ignition module. Installed all of these and followed the owner's manual on adjusting the governor. I had a hard time getting the spring to go into the hole I wanted, so I just clipped it on the arm and tested it. It started right up and had stopped surging. So I finally finagled the spring into the hole, put all the covers back on, and voila! The starter will not spin or engage. It will spin and engage if I "jumper" the starter from the battery, but will not start (this may because I did not have the clutch pushed in). So what did I do wrong that caused the starter to quit responding to the key?
LOL! I'm so dumb. The positive battery cable was loose. That's why the starter would not engage. But here's an oddity: The throttle doesn't change any from the run position down to the lowest position. It does change moving it up into the choke area, but not down.
