Thanks Pete and Pat. I’ll try what you have recommended right now.
sequence of events....Nov of last year purchased used. Smoked perfectly for a few days. Added Lionel smoke fluid occasionally without problem during that time period. Around day 4-5 added a half to 3/4 of the dropper of JT Mega-Steam accidentally. Squeezed to hard. Wasn’t able to get it to smoke again. Ran it off and on for a few days. Reset the loco to factory TMCC settings via reset. Blew down the stack a few times and placed it overnight upside down during those few days. Switched the smoke lever off and on a few times. Still couldn’t get it to smoke again. Gave up, figured it needed repair.
The loco sat untouched from Jan of 2021 to yesterday. When I placed it on the tracks it started to smoke within 30 seconds and smoked perfectly for the next couple of hours of run time. Shut down for the night while it was smoking. The next afternoon, fired it up and it would not smoke. Hit AUX1 9, not too long to burn anything up, 1-2 seconds max. Still nothing.
