I took apart my carburetor and cleaned it a little. I took it off because of an idle and full throttle bogging. None of the jets were clogged, I sprayed carb cleaner to just make sure. My question is are my vacuum tubes correct. I have searched for diagrams, but none show the correct tubing. The black piece to the left of the carburetor. Any help would be much appreciated. Also it is a pain to start now worse than before lol. And it has a new spark plug in it.

Here is a video of me trying to start it. Right before this I cleaned the jets and carb. I put oil in because it was too low, but wasn't paying attention and accidently filled it up the entire way fml. I'm going to drain it a little in the morning. Near the end of the video you can hear what is sounds like to me air being pushed out. Can anyone help me.

I found out why it doesn't look the same. Its because its a wr400 Carb lol. I guess the guy that traded me the bike didn't know what he was talking about. He said it was a yz but i pulled the diagram of a wr400 carb and it matches mine lol.
