I love the term "Mao's Revenge" 
Your method is for sure the more professional leading to stable results. The conductive grease is sometimes a quick fix for simple cases.
I remember your thread about pickup problems of the Genesis MP15AC. The plastic frame of the trucks prevented the axles to securely touch the brass bearings. The conductive grease cured some of mine while some needed a more rigorous repair action similar to yours.
The symptoms you describe for "Mao's Revenge" sound similar to my very first US and LikeLike engine. I got the axle in the brass bearing block oiled. The oil was a totally unpredictable isolator. A firm break in solved the problem temporary that came back ofter some time of rest.
It was a nightmare until the axle and brass bearing got an intensive alcohol bath. Some say oil in the LifeLike brass bearings should be no problem. My experience differs a lot. Anyhow the bearings of your engine look different but the symptoms are similar.
