YZ426F Hot start..how does it work?

I own a 2000 YZ426F and i am wondering how the hot start works, and how it differs from the normal cold choke? do they both choke the engine? thanks would appreciate an answer

The hotstart leans the mixture. All it does is open up a hole in the carb to allow more air to enter the intake on the engine side of the slide. If you ever take you carb off to clean it, you'll see its just a pin that slides out and reveals a hole.
