I'm glad you're squared away on that Bill. I have early and late Mikes, and Pacifics. Have changed a few Seuthe's along the way. I too tried a bunch or smoke fluids. I found that those with low viscosity (more like water then syrup) work best. Examples include ANormal1, LGB blue smoke fluid and track cleaner (discontinued I think), Seuthe fluid (of which I have some if you want to buy it, works great as you would expect, but don't like the smell it gives off or lingers), and Lionel Premium Smoke Fluid (not simply Lionel Smoke Fluid, that contains some water). While finicky and not as good by comparison to modern fan-driven smoke units or Gilbert for that matter, a decent Seuthe with the right type and quantity of smoke fluid can be fun for quite a long time. I found that starting off with 7-9 drops into a dry unit and then once running adding more, but even then limited compared to fan or Gilbert, keeps one putting out a fairly good amount of smoke. Keep an eye on it though. Running a dry one will ruin it. Early TMCC engines also had voltage reg problems that didn't help matters. Another story.
Which fluid are you purchasing from Walthers?
