212 dies after pulling Gs

[shewannameetkarty]

hi, I have a predator 212 with a stage 1 kit from gps and I put a .038 jet in it since it was running lean with the .034 I got when the .036 it came with was way too rich, and it runs fine it does tend to "run out of gas" for half a second while cruising at lower rpm but loves throttle and acceleration, but when I go to my local parking lot and pull Gs on the track the engine doesn't want to keep running, the oil sensor is disconnected and there isn't anything blocking fuel lines and replacing the carburetor didn't help

Gas tank vent blocked or restricted???
Those stock style carbs get slung around pretty hard and stay running. Even a .038 jet is not gonna run the bowl dry at WOT.
Sounds like a fuel restriction somewhere.
