Default WOT cut out

Having some issues with my gy6. It has been cutting out at WOT and kicking back in. It does this constantly and for the life of my I cannot figure out where the problem lies. I swapped my manifold out to one of the 30mm with riser tube and don't seem to have any sort of vacuum leaks. Switched the fuel to gravity fed, thinking the fuel couldn't keep up. Swapped out electrical parts with extras I have (coil, rectifier, cdi). Only thing I haven't done is readjust the valves. Last I checked they were good, and I haven't really ran the buggy since then but to idle and wear the new piston in. Any ideas? I am stumped.

Do a video, but it does sound like the main jet.

Well I swapped jets. Both higher and lower. Still cuts out. and now it completely cuts out and will stall the engine if I don't let out WOT. I am stumped. On top of that I am having starter issues. After running for a bit all I get is a click at the solenoid. however jumping the terminals with turn the engine over. Any ideas?
