Jerry,
I'm looking at developing some endhousings - one small problem is the
ports.
I noticed Richard Sohn is going P-Port as well in his single rotor.
My concern is the rough idle at low RPM, how are you getting around
this
particular problem ?

BTW great work mate, I'm looking forward to see the drawings for
greater
clarification.

Rough idle is supposed to go away when the butterfly is located close
to the port. That is what PowerSport does and I have not heard
complaints about their idle.     Maybe the rough idle thing is a little
bit exaggerated. I have seen p ported race cars with a carb about a
foot away from the port  setting at idle.  It was "rough" but not that
bad.  Some  round engines are worse.  Jerry
