gas leaking from front carb

[stejm]

In the past 2 weeks, I've noticed the distinct smell of gas in the cabin. Thought my carbs might be running rich, but as the car is purring like a catnipped feline rolling in a field of free catfood, I didn't give it much thought.

Cut to today...

I noticed a small puddle on my parking spot at work when I was backing up, so I hit the nearest gas station to have a look. Sure enough, there was a steady drip coming from the front of my engine. I grabbed a drop, and to my horror I realized it was actually gas.

Pulled the air filter, and noticed a steady drip coming from my front carb. Right where the fuel line goes into the side of the carb. I tightened the screws (three in a triangle formation) on the front of the carb and washed away the gas that had pooled in various places. Seems to have stopped the leak for now, but I'm a bit freaked out.

Thoughts? A seal?
