Getting ready to start and break-in my Evolution .46NT I know the high speed adjustment is the one on the rear of the engine. On the front there seems to be three adjustments,
(1) a screw with a lock nut near the air intake,
(2) mounted on a blue ring is a small peg that adjusts about 90 deg. Before it hits one of the two stop tabs,
(3) there is a small flat head screw inside the blue ring.
What are these and how do you adjust them?
