Im running a 14mm Bing with:
Needle, 2 ring, second down from top
I have used the 24 slide, the 51 slide, and the modified 24 slide and its still a little rich right off idle to the point it sucks up hills. The clutch is tuned to the max. Im going to shave the slide a little more but wondered how far those of you doing this go.
It runs the same with my modified 24 slide and the 51.
