I've been re-building / repairing lots of smoke units in the past 5 years.
The ARE the achilles heal of most engines. In repairing Lionel smoke units I have notice the following
The puffing smoke units produced in 2002 steam engines and earlier were poor smokers compared to today
The fan driven smoke units are better but the resisters were not consistent in ratings, the nylon sleeves charred and burned out, the smoke regulator boards were separate and prone to issues. Also alot of the steam engine features/smoke features were not consitant, some chuffed, some constant all the time, etc.
For diesels; I always replace the wadding, cut the nylon sleeve off and suggest a needle applicator to fill the smoke unit.
I pulled off the nylon sleeves, replaced the wadding material with material from a tiki wick and opened up the hole in the regulator board to 1/4".
How hot should the resistor get? Mine seemed to top out at about 150F.
