I agree with Mike100. Go back to the first start up after rebuild. Has the car ever run properly?

I wonder if there is some fundamental timing or fuel problem that was masked by the seemingly OK operation that was really just the engine running in Ignition Module spark control mode ( I can't remember the correct name, but it means that the ECM is not controlling the spark timing.)
