I suspect your smoke smell comes once the damper is set because the turbulence in the pipe creates a rolling motion fooling the smoke into thinking the draft has been reduced.
As far as the pipe gap, the single wall reducer that you have is prob sufficient without stove cement if you can get screws into the flue collar to pull the reducer tighter to it.
