First, wow, is it nice!!! Put my 20 drops of smoke fluid down the chimney, then I couldn't believe how tight the whistle was on. I was afraid I was going to break it trying to pull it off to get smoke in for the whistle steam.
Two things I noticed that I don't think I've ever observed before.
1) The smoke coming from the stack appeared to be a bit darker than that coming from the whistle. (No egg nog involved)
2) After running 10 minutes or so I shut her off to return about an hour later. Started her up, no smoke from the stack. Shut it all down and toggled the main smoke switch off/on and restarted. It then appeared fine.
I'm wondering if it might be a loose wire or if this smoke unit may have some known issues?
Thanks for your help!!
