CH23S over revving
Long story short, My son gets out of the Navy next month and starts with the Pipe fitters through the VIP program. We were given a Lincoln Ranger 250 to get him started. It has a Kohler CH23S 76635. When it last ran it was running on high idle, when it started running even faster and blowing black smoke. The owner shut it down in about 30 seconds and has never tried to restart it. It appears to have fuel in the oil, but running rich enough for the black smoke, could do that.To me it sounds like carb / governor issue, but being unfamiliar with Kohlers and not finding a manual on their website, I'm here, hoping for some insight, before beginning work on it.
