O.S. 46AX 15481004 ABL w/Muffler OSMG0547

As the replacement for the high-performance 46FX, it's no wonder that the .46 AX shares many of its features. The raw power. A remote needle valve. Mounting bolt patterns. A balanced "D"-cut crankshaft supported by dual bearings. CNC-machining for the piston and other parts. And the same exclusive ABL cylinder liner that has made FX reliability a byword. But all the same, the 46AX is a different - and better - engine. Why? Because times change and technology advances. And because O.S. uses the best of both to make a good engine a better engine.

Features

• Features the 46FX'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
