Zachariah, I feel your concern (I think I hijacked one of your threads in Spring of 2018 on smoke units). Messed up my Big Boy by either overflowing smoke units onto the boards or overheating by not feeding them enough - result, frying an RCMC that Mike R. repaired along with all smoke units - see https://ogrforum.ogaugerr.com/...45#79142442594295045
I take an interest in threads involving smoke units. Got a lot of info from 'laidoffsick's' threads: https://www.youtube.com/watch?v=WRcpFRtA6IY https://www.youtube.com/watch?v=1asUWbJtfok
