Thanks,

I suspect I will have to live with the fouling until I get EFI running
as the current DCOE is seriously rich at low RPM (i.e. in traffic). Not
my choice I hasten to add.

Rotaries tend to be a particular b*tch on plugs--as the plugs never get
a
chance to cool off  during the "overlap" and intake portions of  of the
cycle, as they do in a piston engine.

For a rotary, I would say go absolutely as cold as you can get without
fouling, and also to as erosion resistant a plug as you can find--yep,
Autolites are pretty good in this regard.
