OS .75AX ABL ENGINE (OSMG0575)

Power up your big bird the easy way: simply swap out your 61FX with the awesome 75AX ABL! It uses the same mount and fits the exact same bolt pattern, so there's no modifications required. The angular head not only looks sharp, it also significantly increases surface area for better cooling. A diagonally positioned needle eliminates the need for a remote needle valve. Plus, you get a Power Box muffler that's small in size, but robust in volume.
