Zee, call Sudco. They might have a jet not listed. They are very helpful and were VERY good with directing me to the correct needle. You are going pretty far with the needle. Cam is the expert on Jetting. I just know from his experience helping me with my jetting woes years back. Infact, he was helping me even to the point of breaking my arm workong on that jetting issue. LOL
Learn from example: Start with the pilot and move up to the needle/mainjet. As Cam said, post in the jetting thread and he/I(?) can help you start from the bottom up.
