Hello All,
Steve, good explination about the third spark plug.  Ken at StarApex has
suggested a high pressure line from the other rotor, using combustion
pressure to provide already burned gas to the leading edge to eliminate
the unburned fuel problem.  Seems like a good idea - will this work?
May cost a little power but should lower BSCF and some of the waste heat.  :D

The first thing Ken  needs to do is get StarApex working with the high leaning
angle. That is probably the reason Felix did not choose that configuration.

Feeding back heat and fire from leading chamber was proposed on here years ago.
I can look it up. Perhaps Ken read about it on here :)

The trouble with it is the fire goes out because passing it back
through a tube cools it too much or no O2 I suspect. One might get around that
by injecting fresh air and a bit more fuel.
