I just purchased my first outboard motor yesterday and was very excited to play with it when i got home but i had to go to work so this morning i decided to mess with it a bit and when i got it to start and idle smoke began to fill up my entire garage so I shut it off and decided to wait a bit and went back and started it and it ran without any smoke is this normal or is there something serious wrong. Any help or tips is greatly apreciated.
