Ok, I was driving down the interstate with my friend following me. So we decided to go a bit faster, and when I gave it some extra throttle it appeared as "black smoke" which I can assume is a rich secondary circuit since the car show no smoke at all when idling or regular throttle. I'm pretty sure there was some carbon in there too since it's been awhile since I've romped on it. Any second thoughts?

 

More likely just carbon buildup in your exhaust,or
a bad ignition system. You would have to enrichen the secondary
side quite a bit to get it rich enough to produce black smoke
on acceleration.
