This is a very well crafted motor.
Haven’t bought a glow engine in several years. I must say, I a quite impressed with the quality of this AX motor. After break in, the idle is very constant, power or best of any engine this size I’ve ever owned and starts super easy. Only issue I had is the o-ring on the muffler allows the tail piece to rotate and loosen the bolt holding it together. To fix that, I removed the o-ring, tightened the bolt and jamb nut, problem solved.

Another great running OS Engine
I bought this for a Hanger 9 Ultra Stick. It started right up using my starter on the first attempt. Recommend this engine for anyone looking for a .60 size engine.
