I can't figure this one out. I changed out the cylinder to a big bore + stage 2 cam. Now what happens is that it starts rough but it will start. It will idle fine for several minutes (turns off by itself though), and as soon as I apply throttle the engine suddenly looses power and dies (this happens almost instantaneously). I checked the intake and exhaust, no problems there, I'm 95% sure the timing is correct, there's spark with the spark plug, what am I missing? Why would it be idling fine but dies with throttle?

So I checked and the fuel system is working properly. The spark plug does have a lot of black sutt around it, but there is spark. Also the engine backfires through the intake when gas is applied
