• Features the .46 FX's durable ABL (Advanced Bimetallic Liner) plating, as well as a new design that automatically centers, levels and seats the head during re-replacement. Head snugs down with only four screws — not six.
• Subtly tapered low-end needle eliminates surging at transition, ensuring exceptionally smooth, consistent throttle control from idle to top speed.
• Redesigned liner ports and a ball-milled inlet port minimize turbulence during fuel/air mixing, making combustion and power output more predictable.
• New high-speed needle bracket simplifies horizontal/vertical mounting — and can be replaced in just minutes.
• Minimizes vibration-induced “creep” and re-sets with a ratchet spring on the high-speed needle and O-ring seals on both needles. A simple rotor guide screw replaces the throttle stop screw — and eliminates spring-related movement.
• Includes a new low-noise E-3010 muffler and 2-year warranty protection.
• Includes a lock nut and longer crankshaft with more thread length, for better prop nut engagement and greater pilot safety.
