Help fixing chuffing Annie

[Super]

I can't tell you how many replacement gears I have bought that turned out wrong but nothing compared to member Ripley in his search for replacement for the Western Steamers. I think he has a Thread here on his ventures to find gears and axles for those steamers. Good thing that Amazon takes returns so easily. I noticed that two of your gears are 2.0mm and the other 2.5, that may make a difference.
