Matt I think I went into detail to state to use a tach and how and why both mixture screws must both be adjusted. If you have a good ear (retired audio eng) you can do it by pitch as that correlates to a finite RPM. When trimming for the absolute edge, eyes and ears are best together.
Larry. Start by just checking base idle speed. A 50 RPM difference could minimize your issue. That’s the throttle stop screw on accelerator linkage drivers side of Qjet.
