Jim, head down to your local auto parts store and ask the guys behind the 
counter to have a look at a Standard Motor Products or Echlin emission
controls catalog.  These have nice little pictures of a zillion different
types of throttle position sensors, I'm sure you could find one to fit 
your application.  It's just a pot, hook the ends to 5V and ground and
read the voltage at the wiper to get throttle position.  Resist the 
temptation to just use a 99 cent pot from your local Radio Shack, they
are not made for the constant dithering and movement that a TPS sees.
Once you get this data, you're on your own...

See my reply in diy_efi subject "Lawnmower Man".  It was originally 
targeted to another guy doing a B+S conversion, I didn't realize until 
just now that there were two of you.  Jeeze, now ya got me contemplating
hopping up the old garden cultivator...
