Engine running lean, stinky exhaust

The car was smoking before I did the carb. At first is was light just when I started the engine cold, then it went away. The smell is bad, I dont smell sweet smell like AF but I have been doing some reading and maybee it is a bad head gasket? Your eyes will tear up if you hang around long enough. Or maybee that Vacum module thing from the Trans leaking into the intake manifold. got me. I'm not the greatest mechanic but I am learning
