Default Fourstroking @ WOT... help.

My engine doesn't run right at WOT. It fourstrokes for about 4 seconds, runs good for 5 seconds then back to fourstroking. I'm not sure what is causing this so I don't know where to fix it.

I took the bowl off the carb and cleaned out what little debris was in there.
Tried the top two grooves in the needle to try leaning out the engine a bit.
Different plug wire, as well as different plugs, and the stock plug...
Still fourstroking.
I don't know what to do, the engine wants to keep pulling, is pulling hard, then squat.

Can someone offer a fix for this or head me in the right direction?
