Bad Throttle REsponse & Inability to Idle

[Livinstrong]

I can't figure out what's wrong with my blaster, the only upgrades I have done to it are a 14 tooth front sprocket and Boyseen power reeds yet it runs like crap. Also, I can get it to idle, but if I go any more than like 20% throttle, the engine dies.

Did you rejet? Is there crap inside your carb?

The air screw is set all the way in, which is the only way that I can get it to be ridable. If I turn it out, then it can idle, but then the engine dies if I give it any more than like 20% throttle. The carb gets cleaned pretty much every weekend in attempts to fix the problem.

I have tried a 220 and 240 main jet but they don't fix the problem, and my carb is spotless.

I just tried that and it won't idle and if I'm at idle like rpms and give it more than 50% throttle, the engine dies.

Should I try to move the throttle clip position down one?
