Although that is a good observation, Mr. Stout,
The 800 type QJ have the same throttle plate and blades but flow considerably more on the primaries due to a larger venturi for those carburetors which produces an average of 207cfm to 209cfm. And the bias changes the percentage of fuel used, but that is yet another oddity of the QJ organized leaks.
Makes for interesting work on the dyno long before heading to the track.
Regards to all that like this kind of stuff,
