I have to wonder if there was something wrong with the old engine or
setup. Did you ever play with the ignition timing before? That is
about the only thing that can make a basically healthy engine give such higher
fuel burn. (retarded ignition timing). Anyway, glad you found the
extra efficiency & power. Even with a bit more weight & drag,
your -6 should not have been that much different than my -4.

I would expect ignition timing to be advanced right through 30-35 degrees
with LOP operation.
It would appear as very high octane fuel to the rotary. If you notice EGT
go up slightly with leaning, that is the cause.
