The oil was darker than I expected, but there were no contaminants noted or metal shavings/filings. After removing the gas tank guage unit with associated copper pipe for the beginning of the gas line back to the engine, we discovered that both the guage unit and the pipe were both leaking. I ordered all new stuff from Clark's but then my helper went ahead and brazed up the pipe attachment and scrounged around for appropriate washers/bushings for the sender unit and we succeeded in putting it all back together with no leaks.
Next was to work on the idle problem. Mark Durham had suggested in a post that it sounded like the carbs were not set up correct independently before connecting them and he was "right on." We got all that smoothed out, put the timing light on it and made a few minor adjustments to the distributor. VOILA, we're good to go! Now if I just had tags and insurance.
The smoking has stopped, except at real high rpm bursts (4k-4.5k), and that's only for a second or two and is black, not blue. After yesterday's running, the other smoke, which as Mark had also mentioned, was apparently burn-off from all the new parts with oil residue, etc.
Thanks to everybody for your help so far. There'll be more questions as I go along.
