Final pic before signing off on this thread
Kinda PO'd I did not take any images of the actual replacement process. It was kinda stuck and I was worried that if it just popped out and ended up bouncing around on the workbench - which is what usually happens - I wouldn't know the correct way to reinstall the new one. Anyway the manual calls it the "needle jet," but I think I like your terminology better - jet bridge makes more sense. I had to use a long narrow pick to insert through the throttle body to force the jet bridge out through the top into the float area. As I mentioned there was some yellowish build-up that I cleaned out. Happy to report that all is now good.
