Looking for a good locomotive mechanic, I have a Kato BR 86 that I've kitbashed for my logging layout, the thing doesn't run worth a darn, any tips. I've lubed it, cleaned wheels, put on metal wipers, with no luck. It just stutters about the track. Secondly, anyone ever re-motered a bachman 0-4-0? what motor did you use and where did you get it. thanks.
