Figured it out albeit a little embarrassing. I had a little difficulty setting the timing after replacing the intake and had ended up with only a 4 degree advance in order to get to run reasonably well. Still, just didn't feel like it was running right. Did a little reading last night on the forum and it prompted to see if advancing the timing would solve the problem. Well it was quite to the contrary. Some in early last year, in the process of trying to determine the max advance of the distributor, I had made a timing mark with white paint at 32 degrees advance. Well dumba** me had been using the 32 degree timing mark in stead for the factory mark( which I had also marked white) on the crank pulley. Used the correct mark set it at 12 degrees and runs like a top and no smoke.
I hope this post will someday help someone diagnosing the cause of smoke. Too much advance can make it smoke.
