Carb tuning help

[Danman2540]

My bike has gotten to where it won't start at all without the choke. Even with the choke, it starts and dies and starts and dies, each time running a little longer, until it FINALLY stays running, but still not that great. I tried the normal cleaning the jets, but they were already pretty clean. And it still does the same thing. What should I try now?
