@ns1001 posted:Finally got a Lionel diesel to smoke after first refill. Solution is to use a bottle with a needle allocator and push the needle all the way down into the smoke unit. Diesels I bought 2,3 years ago no longer have a no smoke problem. Why does Lionel not include a needle applicator with each engine.
I didn't know the Lionel diesels smoke. I learn something new every day. Thanks!
