550cc is way more injector than you need so I'm not surprised it's running rich.=A0 (= why are so many doing this?)=A0 Don't worry about what the steps in Mode 3 represent, just reduce it until you get what you need.=A0 Of course the instructions tell you to adjust Mode 3 at a high throttle setting, not the = low end you mentioned.=A0 Mode 2 is for the low end (assuming you have the current version of software, see manual).=A0 Adjust Mode 3 first,=A0 test for possible need to adjust Mode 6 at staging point then do Mode 2.
