Assuming your float is working properly in the carb, it could be that the diaphragm in the fuel petcock isn't responding to the call for more fuel. You might take the petcock apart and make sure there are no tears in the diaphragm.

Hard to diagnose some things over the net. good luck.

You might want to try starting it with the petcock set to prime. That will tell you if your petcock is starving the carb for fuel when you throttle up.
