Clear up after running it for awhile? If so may have valve seal problem.

Valve stem seals leak a little oil by the valves, after sitting for awhile it will smoke until it burns away this oil. Your brother is right in one way it will stop after it runs a bit but is probably going to keep doing it each time it is started after being parked.
