     I had originally considered using a carburetor instead of EFI, just for simplicity. (No high pressure fuel pumps, fuel returns, etc). I was not sure how to handle the leaning reguirements that go along with changes in altitude. I hadn't considered using an aircraft carburetor.
 
If I were going to try to use something other than EFI, it would absolutely be an Ellison throttle body.  I put one of those on my old RV-8, and it really worked great,  even when flying inverted :-)  Nothing could possibly be any simpler, though they aren't cheap. 
 
Cheers,
Rusty (will fly for Argon)
 
 

   The Elison throttle body wont flow enough air unless you run two of them with is cost prohibitive.
  I am running a 48mm Weber and love, I have an air ram setup to create a pressure difference between the Venturi and float bole for mixture control and it works fine.
