Well, I played with the medium speed needle, but only because there was slight hesitation at part throttle. I still haven't reattached the return line. I'm going to play with the adjustment with the line reattached now, because messing with the needle only made the overall performace worse. I'm hoping with the return line connected correctlly, I can tune it correctly.

Does anyone know what the factory adjustment is on the medium speed needle on the O.S CVRX 18? I didn't check before I started fiddeling with things[:@], and I want to make sure I'm not running around in circles. It doesn't say in the manual.
