Or have I over simplified it?
Thanks!!!

where can you get the wadding or wicking for these units? couldnt find it on the lionel website, Or a good substitute?

Jeff T I modified my old Challenger from 27 ohm to 24 ohm ceramic wire wound resistor. The inlet air hole above the fan was enlarged to the ID of the fan. The direction of rotation was changed for max air flow and the die cast outlet was drilled out to maximize air flow. I repacked the bowl with pink fiberglass insulation to the bottom of the air notch from the fan side to resistor side of the bowl. I would recommend a 25 ohm resistor as the 24 ohm ran a little too hot. Use Mega Steam or the new Lionel fluid. My rule of thumb was to measure the resistance of the existing smoke element and decrease the resistance less then 10%.

If I hold the smoke boost down for 4-5 seconds, it smokes great, but when I let go the smoke is almost non-existent. Is this just the way it is or is there something else to try?

Took my Lionel T1 apart trying to do the upgrade Lionel has posted on youtube. My pcb board under the resisitor looks pretty fried. Board is blackened directly under the resistor. Is this normal wear? Engine never smoked well since I've owned it. Did anyone else have a blackened board when performing upgrade and smoke unit worked upon completion?
thanks for your help!

yes and no..On lionel from the parts breakdown pics they dont have that gasket running under the resistor ... On the MTH smoke units they have a heat restance gasket that runs under the retire area where the resistor is at. thats supose to protect the board.. well I did that mike regans mods to my MTH smoke unit and man it goes it blows away Lionels !! But my gasket was bad..I'd ran it without it .it almost burn up my board..So Id cut out a piece of copper tin and placed it where the gasket was at and used copper high heat automotive RTV.. woked out great..I use the RTV on my exaust headers to seal my gaskets with no proublems! That copper tin acts as a heat sheild to that circet board..
