As most know, I got my PPort back from MazdaTrix two weeks ago or so,
and have been busily reinstalling it into the airplane.  Last time I ran
it I was puzzled by two things - the strange low temps in rotor 2 (a
symptom that the pport was leaking) and the rough running of the engine
in general.

Well, this weekend as I was reinstalling the engine I fabricated a
supplemental wiring harness to allow me to easily trace the wiring to
the spark igniters to confirm I was hooking them up correctly.  What I
discovered is that I had the igniters reversed for each rotor -- rotor 1
T and rotor 1 L were swapped.  Similarly rotor 2 T and rotor 2 L were
swapped.  Would this explain the rough running I experienced in the past?

It might Mark but don't expect smooth running until you get
over 3000 RPM. More likely the mixture was not set right
in Tracy's EFI system. Let me know when you want to tune it
and I will come over and help as long as it is not during
Sun n Fun. I think Tracy fires both plugs at the same time
so swapping the plug wires should not matter with individual
coils one per spark plug.
