Carb Rebuild Yields Extra Parts!?!

My daughter and cleaned and rebuilt a 1972 c10 Quadrajet Carburetor. Things were going well until we found two issues, one of which we will order the second is where we are stumped.

1. Our carb is missing the Power Piston Spring, I'm ordering one today.

2. We found we ended with an extra part and can't find a diagram, pic, or anything related to this bonus part: Secondary Air Valve Cam (see stock pic below).

While I know that being more efficient is important, I can't see having extra parts left over from a rebuild being a good thing. Can anyone provide a pic, or an idiot proof reference where this little guy should be located in my carburetor?

Thank you in advance.

Mike
