Kohler 18 to 20 hp

I bought a used Lazer Z last fall. It has the 18hp engine. I have read that it can be raised to 20hp by removing the throttle stop screw and changing the governor spring setting. Well I cannot see how this will achieve this. Removing the stop screw seems to allow higher rpm's but I could have achieved this by putting the governor spring in the next hole. Also I noticed that specs on both engines are rated at 3600 rpm. If the rpm is set at 3600 then how could the hp be raised? Mike
