GRRREAT!!! Good work!
Yes, there will always be lots of smoke for awhile, the oil in the cylinders from assembly will sometimes take a half hour to burn out.
There are always bugs to iron out after major surgery like this and I'm sure you'll get them all taken care of.
The not idling situation could very well be a vacuum leak. It might be related to the hose you can't properly locate. I'm sorry I can't help more with that.
Hang in there and work through it. It feels good doesn't it?
Have a great day,
