Q Jet Secoundary Rods

I made up a fixture to measure the hanger dimensions. Pretty easy to do. I had several Q jets so I sectioned one so I could see exactly how the secondary rod changes with hanger letter changes. K, G etc.
What I experienced on the Dyno, using LL .040 tips rods , thinking I was riching the secondaries, it went lean. Dont understand why??? I found the primary side jet size numbers can be way off, BEST to flow every jet you have to know for sure which way you are really going with your jet changes.

Thanks to all that responded.
