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

Still using the original that came on the 88 junkyard engine I bought 9
years ago.  Guess I ought to replace it soon :-)
