Scott had a few suggestions.
Re-loaded the engine back into the CAB-1.
There is a heat sensor on the smoke unit that may need adjusting.
The heater coil sometimes is too high in the smoke unit's stack and needs to be pushed down with a toothpick.
I reloaded the engine and the engine puts out a light smoke exhaust (more like a full size drifting down hill). I think that's as good as it's going to get. No big deal as the engine is a fine, smooth runner with lots of detail and excellent paint job.
I took off the boiler front plate (held on by friction) but unable to move the smoke unit out of the boiler (it appears to be glued in) for any sensor adjustment.
The heating coil was difficult to look at from the smoke stack so I left it as is (no use rooting around in there with foreign objects).
I was just expecting too much after having MTH's engine smoke.
Each brand has their strong and weak points.
