neww problem,,,,,

so now i know its the float. While riding today it would bog down and fuel would leak bad. Id shut it off and kick it to clear the bowl. Start it run it turn gas on then it would bog down a little further down. I then tried puttin the petcock to a little towards reserve, it would last longer then full on but it would still bog. Whats the proper float setting (measurement)?
Thanks!
 
heres my spark plug:

its a dry blackish brown. And it has a weird plug, BR8EIX....anyone hear of this one? Should i get a B8ES?
 
ok.
So ive removed the airbox lid and threw a 250 main jet in it. Its harder to start (alot more kicks) and when it does start it has a meaner rumble to it (kinda lean but it goes away, it sounds alot meaner then the normal 2 stroke you hear). Should i go one size up on the main jet?
I did let it run for about 10 minutes and pulled the plug it was dark brown and light brown in some places. So thats good......
