It is true that the pulse damper is a well known failure point (fuel leak)
in the Mazda rotary.  Still, Mazda put it there for a reason so I'm still
using mine.  The purpose is to dampen out fuel pressure variations caused by
two sources:  1. fuel pump pulsations and 2.  injectors switching on & off.
Those of you who remove the dampeners could help us all by reporting on any
anomolies you may notice.  The ones I would expect are EGT variations
between the two rotors.  The variation would likely change depending on
engine rpm.  If you get any unexplained EGT imbalances, let us all know.
EGTs should match within 50 degrees or less.

     Tracy,
       Are you still using the 86-88 damper or the later and improved 89-91
