New to flat heads

Iím new to ford flatheads and need some help. Iíve got a 48 ford super deluxe rebuilt the carb this morning and took it to town it runs ruff at speed vibration from 45 mph and up. Take the load off the engine it goes away. It has a electric fuel pump and a regulator on it right before the carb. pump was installed to help with vapor lock only on when turned on with a toggle switch. What should regulator be set at for a stock engine. I think carbs run about six psi but not sure on this engine. Any help would be appreciated
