    I doubt the oil pump is malfunctioning giving too much oil. Very rare for this to occur. It sounds like a fuel delivery problem. When you say rebuilt carbs,were they rebuilt with new kits? Was the pop off psi set properly? I would also check the fuel valve for obstructions or damage. Be sure the lines from the tank to the carbs are flowing freely. Check these items and i bet you will find the problem. Its starving for fuel at high rpm.
