I managed to get a solid 60% better output using the stock resistor.
First take off the sleeve. If it is burnt on use a little alcohol and ...Gently!....use a toothpick to move some of the sleeve residue. If it is too far gone, use a new 28-30 ohm resistor.
Next I placed a piece of MTH wicking a little longer than the resistor standing up along side the resistor with a little sitting on the bottom so it can wick up the fluid. Once closed up the resistor holds the wicking in place.
This smoke chamber is divided in 2. Keep the wicking in the same chamber as the resistor. This is important. The MTH wicking worked better for me than the Lionel wicking for this application.
