I'm confused.  In my experience, even .016 is an anemic gap.  Check

out the

gap on a stock Mazda rotary plug (not adjustable).  It's something

like

.040" - .050".

Just a note; A few years ago I converted an O-200 to full MSD,
set the plug gaps at .065 & has been running fine at that.
Some race cars run them at .070-.080.
