I figured it was from running too rich, as oil smoke tends to be blue.
I just checked the valves as a routine thing seeing the engine has only 600
miles since rebuilding..I probably should have retensioned the head first,
but I had done that after just a few miles.

If your clearances are too small then your valves may not be seating
properly after the engine is warmed up, allowing gases to blow by and oil to
seep in to chambers after turning off. That would give a puff of blue smoke
on start-up
