I have made another significant discovery regarding smoke production in my LC+ B&O:
First, I was starving the unit of fluid by using the MegaSteam needle dispenser; the drops of fluid out of it are micro drops - you have to at least double the number of drops (good dispenser though, great for getting fluid down the stack). However, as soon as I began using the Lionel pipette and putting 1 line of drops in the stack, smoke production went from anemic to almost as good as my Big Boy.
Second, I was being conservative with my ZW-L and only supplying about 16 volts to the track. Today, I increased that to 17.96 (all the way up on the ZW-L lever), and the smoke unit came to life almost immediately with Big Boy like smoke production - well darn close.
