How are rotary engines balanced?
With a rotary engine, (the Mazda 13b specifically in my explanation) there exist two rotors that spin about the eccentric shaft. The rotors are typically arranged so that when the front most rotor is in a position where the apexes are facing (N, SE, SW) respectively, the rotor behind would be positioned where each apex is (NW, NE, S) (using compass directions for lack of a …

Singer 153W102 feed eccentric troubleshooting
Also at that point, the head of the feed driving arm moves slightly away from the feed eccentric. Considering the shape the machine was in when I started, it's a small thing, but I don't like the turning resistance. (The gap between the feed arm and eccentric was much larger when I got the machine!)

any rotor with mass eccentricity can eventually appear to be balanced perfectly well in a balancing facility, since it is operating in an uncoupled condition. However, when the balanced eccentric rotor is reinstalled in the field and coupled to other rotors, it very often has excessive vibration and doesn't run as expected.
