I have two MTH Bump-N-Go Trolleys (30-5143 & 30-5146). After I lube them (per the Manual and 1 drop per spot), for a few days(10-20 hrs of running), they don't run smoothly. They hesitate with no pattern of specific spots on the track.
During Christmas one runs under the tree on 6ft of 0-27 track(2-35"+1-5"). The rest of the year, I un one on 10ft of 0-27(3-35"+1-10"). Both use Lionel 26/260 bumpers.
Am I missing something or using the wrong oil?
