00 Flying Scotsman – Repaired Running Gear

Neil would like some help if you have a Flying Scotsman train or understand the workings of running gear:

“My son’s Flying Scotsman lost a hex screw from one side of the running gear recently (it is 3 months old). Returned to the shop for repair under warranty. It runs but seems to me to waddle or fish-tail, especially at slow speeds. It does this forward and reverse. Should it do this? I think the running gear left and right are out of sync with each other. Should they be in sync? Seems to me the wheels on one side have rotated leaving the drive for the left and right sides out of step. I think this could have happened when the hex screw came off while running. Any help appreciated.”
