Every one of the governor designs I've seen over the years are designed to close the throttle plate. They are designed in this way because no matter what it's application an engine always starts under some amount of "load" wether it's coupled to a piece of equipment or it's just the extra load of having to start with cold oil, etc in the winter. If it were to start with the throttle plate closed there wouldn't be enough initial flow through the throttle plate to supply the engine with the needed air and fuel to getit started and up to a stable speed. Basically it would be like putting your tractor in gear, blocking the wheels, and trying to start it. You'd never get the engine turning fast enough to gain the needed, initial momentum for the governor to take control and open the throttle plate. When starting with the throttle plate wide open it will provide maximum flow through the plate which allows the engine to gain speed rapidly until the engine gets to the set speed at which point the governor takes control and shuts the throttle plate to restrict the flow and control the speed. This is more or less a simplistic explination of what's happening but I hope it'll give you an idea of why they do it the ay they do.
