Default Re: carb adjustment?

Okay, I'm out of ideas. I've changed back to my previous spark plug, adjusted the carb needle to every level, and even switched my oil mix back in case that was messing with my fuel:air mixture. Nothing has even had a noticeable effect. Even switching the carb needle from top to bottom does not havea noticeable effect. The only thing that I do that has an effect is when I take the air filter off completely, it gets noticeably better, but not completely fixed.

Sometimes at WOT it will go for seconds without ever firing once. It's like the killswitch is being pressed. But I doubt CDI part of the engine has any blame since the removal of the air filter helps.

Does anybody else have any ideas? I'm stumped here.
