My Mk 1 concentric currently has a 106 needle jet fitted, with the needle at its highest setting (clip in lowest position). I want to richen the needle stage by the "one step", so when I fit a 107 jet, I assume this richer step will be acheived when the needle is then set a its lowest position with the bigger jet (clip in top groove). Is that correct?
