Here's another easy test:
Crack the thottle about half open and see how much side-play is in the throttle shaft. i.e. clearance between the shaft and casting. A proper rebuild would include drilling out the housing and pressing in a brass insert. If rebuilt properly there should be an 'interference fit' between the shaft and brass bushings. If not done properly this could be a source of air leak and whistle.
I don't know if they did the brass inserts or not.

I put the throttle half way and I can move the throttle side to side. Not sure if that is what you mean but I can move it laterally. When I pull the throttle out from the body, I can get almost a penny wedged in.

Yes, she was full warmed up real good.

What do you mean by QC ... to me that means quality control.
