Thermoquad questions

Just picked up a thermoquad off a 72 340 along with the intake manifold.

For some reason, when I line up the carb with the holes on the intake, part of the throttle arm of the carb hits the intake, preventing it from sitting flat. Do I need a spacer, or am I just not seeing something?

Also the secondary air door has no spring tension whatsoever. I tried tightening it to no avail. This is my first thermoquad so I honestly don't really know what I'm doing.
