A very special forum, great people. I opened up the 2025 and checked everything. Looked fine, straitened some wires and runs like a champ. Installing a new smoke unit and will test. Thank you, Bob

Thanks for the great info. A couple wouldn't even squeak. Carefully took them down, cleaned and very lightly oiled and they came to life. Most of this was my fathers and wrapped in the Chicago Tribune papers dated 1967! As I stated more ?s. Most don't smoke. Tried running in neutral to heat up (cleaned the plunger and vent, added a correct spring) We are talking about a early 2025 and 2035. Stick with pellets or convert to liquid? I'm in a very rural area so both would have to be ordered. I have the K-line service manual and have been using Lionel grease and Lucas gun oil where indicated in the service manual. One last ?. The 2025 was running very slow and the smoke element was glowing bright red. I had never seen this before as best I can remember. I disconnected the heat element and she is now dead in the water. They run when they don't smoke so why when it is disconnected would this happen. I'm pretty handy and have been a part time gunsmith for many years but a lot of this is greek to me, Sill its fun a what memories! Thank you all again, Bob
