On a Holley carb, there should be a fuel level adjusting plug on the side of the float bowl. With this plug removed, the float level should be adjusted so fuel just starts to run out of this hole. This level will give you the best performance and economy.
On the "white smoke" issue. I've pulled a lot of motors and in doing so, it's almost impossible to do it without spilling some coolant into the exhaust header pipes. If this be the case, it takes quite a while for this to burn out of the system. If it persists, you may want to be concerned.
