I'm the one that switched to the 9886 as Neal and Hambone suggested and feelit does free it up but am new to the short needle carb as I see you love Frank and think I finally got it I was having a hell of a time getting a consistent idle so I was telling Hambone who has helped me at at the track and he suggested to richen up the mid a 1/4 turn so tried that and I think it has helped the idle and the tune is more consistent it seems. As much as I love OS the only brand I've ever owned I think my next one is going to be a clockworks B5.
