 Paul/Bill,  Ken shipped the variable intakes to me, hoping I would do
 something with them.  Would  you like to have them?     Jerry

Good idea Jerry. Bill Jepson may have more time.

BTW guys I think it best if we run them upside down from the way
I show them in the drawing. That seems to be the way NSU and
Mazda time the engine for low power and better idle.

Bill,  send me your shipping address

Also Bill this arrangement will be better for low and medium power.
Timing is more favorable over the HP range.
