my exhaust smells bad

[GreenMystChevy]

There's no such thing as a stupid question, just a stupid person. Well, here goes my question.

My exhaust, well, it smells. It has a very pungent odor that smells like gas and/ or something a little different. It's pretty strong.

Basically I was wondering how normal this is and what might be causing it. I know most of my other old vehicles don't smell quite that bad and I know that exhaust does have a smell to it, but something about this makes me think.

The only thing I can think of is the carb running too rich and running a lot of unburnt fuel through my pipes. I know nothing about tuning a carb and how to get the mixture right if that's the case though.

Thanks for the help guys.
