If you over heat it will start to missfire abit and run really rough. thats to hot and on the verge of over heating.
either kill it or take off and let the air cool action work. If you kill it setr till you can touch bare handed the exhaust pipe near the head. before you take off again.

I have no faith in human perfectability. I think that human exertion will have no appreciable effect upon humanity. Man is now only more active - not more happy - nor more wise, than he was 6000 years ago. Edgar Allan Poe
