If you haven't checked it with a timing light, it's probably way too retarded...and you're not getting complete combustion, so it seems as if it's running too rich (spark timing too late for the fuel in the cylinder to all burn).

Still sounds to me like a timing problem.

My base timing is spot on. If you have a better write up other than what I have found then be my guest and show me. Base timing at tdc is spot on is what I mean, I went over this on page one of this thread.
