Perhaps I am missing something here?

To my mind there are 3 jets in the carby:
1) The Main Jet
2) The Slow jet (or idle jet)
3) The Power jet (sometimes referred to as the air correction jet?)

I suppose the X and Y joints in the air correction circuit could also be considered a type of jet?

Are you able to say which one you are talking about?
Perhaps a photo?

Have a read through this page on NSR-World
