Dissecting a 4-Stroke Carb and How To Troubleshoot It

This is a carburetor from a Chinese made buggy / go kart, but it works the same as all other 4-stroke carbs that look like it.
I will go over how to clean it, inspect it, and troubleshoot it.
Feel free to ask me any questions. I will respond as quick as I can.

I apologize for the parts that are blurry. I realized it after I got it up and viewed it.
