Good afternoon everyone,
I don't know if anyone has done a thread on these puffer units, sorry if it has been done before. I figured I would pass it along if anyone is interested.
This morning a very nice fellow forum member came by my house and he was telling me that his Lionel J1A had a puffer unit in it and the smoke output was poor at best. So I opened her up and I completely dismantled the puffer unit and started a complete rebuild on it. What I did was put a new resistor in it and new wick material. There's also two small holes that lets the piston of the puffer unit push air into the smoke chamber. I decided to drill these two small holes slightly larger and we ended up with an awesome smoke output.See photo's and video below.
THANKS FOR LOOKING, ALEX
