Help Please!!

I went out this morning to my bike and I decided to check the e clip. First I took the bowl off and it looked good. So i put that back on and went to the e clip. It was on the 3rd notch so I moved it up to the second notch. I took it for a ride and I automatically noticed it was a lot slower. So I went back and put it back to the 3rd notch where it origianally was but when I when I went back out for a ride it was still a lot slower than what it was. Does anyone know how to fix this?? I'm getting mad at it and can't figure it out!

It's hot here 2. But i've ridden in this hot of weather. What I thinkin is that I'm going to change the mixture to 32:1. I think what might be happening is the plug getting fouled up since of the rich mixture. So I'll take the plug out an clean it. And try the 32:1 mixture.

I also forgot to mention that when I try to adjust the idle, nothing happens. It just stays the same. I'm not sure what to do. The only thing I did was take the bowl off along with the needle and float assembly. Put it back together and then changed the e clip. Not sure how doing that would mess anything up
