Mine does the same thing, but I don't have any starting issues. The tank vents to atmosphere (directly or indirectly depending on whether or not the emissions parts have been removed). At the same time, if it's getting too much fuel, there could be unburned gas in the exhaust. I would recommend checking the spark plugs. They will tell you a lot about what's going on. There are also a number of threads on here about starting issues. Start with a search in the Vulcan Verses and expand it into a general search.

Sometimes the petcock can have a slow leak as the fittings are just pressed in, so one can leak slow enough not to form a puddle.

You can turn the petcock to "off" when parking (lever pulled towards the back of the bike) you just have to remember to turn it back on when you start the bike.

If doing this stops the gas smell you likely do have a petcock leak or a clogged float valve.

Smell or strong smell of gas around a parked motorcycle?! Yeah, something wrong with this picture.

Everybody knows how easy it is to check the gas level in the carb bowls. Right? I like to check with the motor running on the center stand also.

edit- if the level is not too high, wad a piece of writing paper and place in the V under the carbs. Leave while parked. Carb and tank vents should not have a gas smell. All tanks and all carbs are vented.
