I've just acquired a Lima loco that's pretty old (25 years, to be precise). Before running it, I gave it a good clean up, and lubricated it etc. Motor appears to be a Ringfield, possibly 3 pole, bogie mounted.
However, after about 10seconds of running, there is a nasty smell of electrical burning eminating from it, but it still runs very well.
Is there anything I can do to eliminate/minimise the smells ? Can I give it a drive transplant from a newer model (but retain the original for resale etc)
Given it's rarity and age, I don't intend to run it often, just for the odd "specials", but I do want to keep it in good running order.
