Common occurance .... a slight amount of oil leaks down the intake valves when the engine is sitting for long periods of time. When you start the engine the oil is sucked off the intake valves and burned which is the smoke you are seeing during startups. It’s no big deal don’t worry about it unless it starts to get worse.
