(i read this in a rc car bokk i bought but it was an older edition)
the high end needle is easiest to just set by feel, start where you know its too rich and then lean it until it produces the correct power a bit at a time. drive it around for 3-4 minutes at a time and make sure it doesn't start to lose power or feel different, that means you're close to too lean.
