I say run her a while like that. I don't disagree with any of the above, but until I ran her a while like she is, I wouldn't go fiddling with the adjustments. If it is running rich while in the garage, that is not unusual because she probably is not getting warmed up to operating temp there. I would check the fuel pressure to make sure it is not too high, but those dang Webbers are miserable to get right. I also agree with the SU conversion idea!
If she runs great on the road...get her out on the road more and don't worry about the smoke in the garage JMHO
