In my zeal to have my UP diesel A unit run more smoothly, I used the grease in my cleaning kit on the wheels as the Greenberg Manual instructs. However, I may have used too much grease, and now the diesel drags no matter how much track cleaner I use on my tracks (O gauge). Is there a way to de-gunk the UP and have it run more smoothly, short of cleaning the track ad nauseum?
Thanks.
