RTR12 - I've had several older RK Scale RS3's and none of them had smoke, only the two RS1's that I have now - NH and Southern. Both of them are pretty finicky however, sometimes they smoke profusely but others will almost quit. :-(
This D&H is the first RS3 I'd seen advertised with smoke..
I was questioning whether mine had smoke or not when I got it, forget the details (been a while) but there were conflicting descriptions. I added smoke fluid thinking it had one and it leaked out the bottom of the engine. I was then thinking hmmm...maybe it didn't have one? I asked here and several folks said the same as you did that they did not previously have smoke units. So I took it apart to to see. I found the smoke funnel and gaskets out of alignment (reason for fluid leak), but it did at least have the single element smoke unit.
As I recall the wick and everything looked OK, but I replaced them anyway while I was in there. It smokes, but has never smoked like the other MTH diesels I have, like the ES44ACs, SD70s etc.. The RS3 is the only older model Diesel I have, the rest are all more modern ('80s to current) so I don't have anything to compare to.
