@B rad posted:Not getting tons of smoke yet but it's good. I don't think I have got the wicking saturated enough yet. Scared to over fill. I have to remember even though the Big Boy is so big the smoke unit probably isnt any bigger than in the smaller LC+ 2.0 locos 😄 but I really don't think 15 to 20 drops is enough for these fan driven smoke units especially with bone dry battling inside.
I use more than that on almost any smoke unit except the tiny ones that MTH uses for whistle smoke and in their little switchers like the VO-1000.
