The old cast iron K series. Have a 12HP K301 in a 67 Ford 120 lawn and garden tractor. I just replaced the head gasket and was adjusting the points, timing, carb etc. It appears the governor is not functional. Tried adjusting it according to the book and get nothing out of it.

What I really want to know is has anyone torn one of these engines apart? From what I've read they start with the governor gear and assemble the engine around it. Well not really but sounds like the engine needs to be completely disassembled to replace the gear. If anyone has rebuilt one, how tough is it? Any special tools required just to replace the governor gear?
