I messed around with that on my DGV as well... They most likely are opening up more than halfway at half throttle, but still, by looking into the throats of the carbs, you can see that the throttle plates still had much more to go to open up... But yes, it probably mostly is just the way i have the linkages setup. But they're all running towards the end of their adjustment, so we'll see what happens when i get my aluminum manifold on tomorrow.

And guess what! The oil leaks stopped!
