I purchased the Golden Memories 773 a couple of weeks ago, and finally got around to running it last night. I noticed that the engine wobbled diagonally (right rear goes up, then left front goes up) while running with or without a consist. The wobble doesn't match the wheel revolutions, so I quickly ruled out a bent wheel or axle.
Upon further investigation, I noticed that only one of the two rear drive wheels has a traction tire. The other rear wheel has the groove, but no tire. I'm wondering if installing the spare traction tire on the grooved wheel will stop the wobble. Does anyone else have this model? Do your rear drive wheels match what I'm seeing?
