One vote for a push/pull pin that will need to be glued back or replaced, and another vote that it's a hex head screw. Has anyone taken off a 682 shell recently who might be able to confirm the correct removal method? What's frustrating is that I made an hour drive each way twice in one workday to the train shop, paid $30 for the repair, and the gentleman only fixed the stray wire issue and didn't even look at the smoke unit like I requested.
The problem: When the 682 is in neutral with the ZW transformer bumped up at 18-20v, the smoke slowly starts to waft out. When I send it forward, the smoke is imperceptible. (My 681, on the other hand, has not had the smoke unit primed in over a year, and it smokes like a chimney). As smoke does appear out of the smokestack while in neutral, I can assume that the unit does work but is simply clogged, correct? I have unclogged the smoke unit on the 681 many years ago, but my fear with the 682 is damaging the side pistons since I'm not sure how they are supposed to come off/go back on...
Thanks again for any/all info and advice!
