Black smoke= rich fuel mixture. Could be due to automatic choke when first firing up or it could be an improper fuel mixture.
Blue smoke= oil burning. This is when you need to worry.
Pull your spark plugs and check them out. If they are black, it is probably running rich, if they are white , you are running too lean and a light tan is a good mixture.
