Smells like gas

[lukecp]

I was driving around town last night, when i decided to light up the tires in my truck and do a really cool smokey burnout. After i was done, i stopped to pull out into traffic, and there was a fairly strong smell of gas coming from the truck (windows were down), it it was idling kinda funky, a little bit slower than usual. The carb is an edelbrock 1406. It then ran fine when i pulled out into traffic. I'm usually not very hard on the truck, so this is the first time it has done this. Is it just unburnt fuel from opening up the secondaries in the carb, and then hitting the brakes to stop it?
