46AXII ABL .46 Airplane Glow Engine with Muffler

Experience the all-out power of the O.S. 46AX II ABL w/Muffler! Features include a squared-off E-3071 Power Box muffler, a 40K carburetor with a rear angled needle valve, a ball bearing-supported crankshaft and an A3 glow plug.


  • Ball bearing-supported crankshaft.
  • A3 glow plug.
  • Two 0.1" x 1.4" (3 x 35 mm) cap head muffler screws.
