Technical Pete Jackson Injection

I picked up a couple of Jackson Injections along with several nozzles.....problem is ,never running the Jackson, I have no knowledge of how to read the sizing on the nozzle. If I could find someone that knows ,I wouldn’t have to flow everyone, so thanks in advance for any ideas.

.021” nozzles( Hilborn 7, 110 bypass pill, gasoline, 4-7% leak down barrel valve. It will run. Good luck.
