Upon further review, my previous excitement may have been a little premature. I drove the car again and it is clearly smoking more - black smoke - while idling. Did I advance it too far? No pinging/knocking though...

I should add that when I checked the valves, all of the intake valves were loose, while the exhaust valves were pretty much on target. I didn't adjust them, because I didn't have my wrenches - and I was always told to adjust them a little on the loose side anyway, as they tighten up.

Would this effect things?
