Just wanted to say thanks again for the help I got concerning my question on rebuilding the carb on the NAA. I got a kit, took two carbs, and proceeded to make one good carb from the two. One of the carbs did not have a power valve and the other did so I kept that feature. One didn't have a choke setup and the other did so I kept that feature. There were a couple other internal differences but it all worked out to finally put one together. I roughly set the valves and reinstalled it on tractor. The old Ford fired right off and ran great. I messed just a little with the idle and power but not much. So happy it came out good. I have been knocking on wood since. : ). I got my NAA back, YAY! Thanks guys. Now I need to go spend some time cleaning up my mess on the workbench. : )

Maybe I’m just not well awake, but what is a “power valve” in the NAA carb?

Hello Jesse ,
Well the power valve (my words) is actually the main power adjustment needle. I just did not know the correct terminology. Thank you guys again for the drawings you have there in the How-Tos.

Fine, thank you. And you are welcome
