Too lean? Doesn't smell like it!

Lean and rich smell the same. Unburnt fuel is unburnt fuel. But, lean and smelling of fuel will have given you other syptoms long before it smells rich, and tying to sniff while your driving is not a great idea...lol In your case, the idle mix is off, or the throttle is open too far, or not enough.. It needs to be tuned. that's all.
