Paul,

I seem to remember that the key to getting Everett Hatch's
peripheral port motor to idle was to place the throttle plates
very near the intake port. Is that correct? How near to the
intake port where they?

I've looked at some of the pictures you've uploaded and can't
really tell.

Are there any other secrets to getting a peripheral port
naturally aspirated motor to idle so you could use it at less
than 2000 rpm idle speed?

Suggestions from the list?

Absolutely the butterflies are right inside the rotor housing.
Electronic fuel injection will also help. The PowerSport
EFI engine run at OshKosh last year idled fine. I am amazed
Mazda themselves never tried that. They tried almost everything 
else.
