Smoke on start-up?

[PltwhtSHO10]

Hey everyone, my SHO has been sitting all winter, and was taken out about two weeks ago for a quick detail. After the detail, the car sat for a little over two weeks. I took it out today, and when I started it, I noticed that a small puff of smoke came from the exhaust. It looked as if it was black / blue but really couldn't get an accurate look due to the sunlight. When I smelled it, it didn't really smell like oil, but kind of like raw fuel.

Has anyone experienced this? Thoughts?

If anyone can comment, it would be greatly appreciated.
