I'm not doubting your expertise, I'm doubting whether it's actually possible to improve on the performance I currently have, given the age, small size, and high-stress of this particular engine in this particular application. I've been working on it for about a year now, and I've had a much easier time tuning larger engines.
I never did understand how mid-range needles work. I know what they're supposed to do, but I can't imagine the physical arrangement of parts that enables it to work as intended.
