 This guy runs a distributor on the trailing plugs and CDI through the
 distributor for the leading plugs.

 Distributors on rotary engines are totally unnecessary as
 one rotors fire every rev unlike a 4 stroke 1 cyl piston engine that
 fires every other rev. That is why distributors run
 at half crank speed.

 Mazda did away with distributors in 1992 with the 3rd gen
 RX7. They replaced it with cheap crank angle sensor or 2.

 Todd can you turn off your html when you send us a message?
 It seems to add an unnecessary space between each line.

As you said Paul, the distributors were not really necessary. Back in the early
'70s, I had a 1973 RX3. One day I was contemplating navel lint and how the
Rotor Motor worked and came to the same conclusion. I timed the trailing
distributor to the same advance as the leading. I then took the caps, coil
wires and plug wires off and put a wire from the leading coil to the #1
leading plug. Another lead from the trailing coil to the #2 leading plug. I
closed the hood and drove to where my buddies were hanging out. I think their
heads are still a bit messed up trying to figure that out. It ran as normal.
The emissions were probably off some.

What is confusing is Mazda used what they called a CAS which amounted
to a modified distributor base for years. Had two crank angle sensors
inside. One lower one for RPM and one upper one for trigger or "home"
as some people call it.
