MOTOR OS FSA-72 II 4T (61N) W/MUFFLER F-5030 ALPHA 34721

Description

The O.S. FSa-72 II is the latest version of the popular, powerful four-stroke engine.
Updates include a revised oil breather system that now vents from the crankcase rather than in the intake to improve running performance. The rocker cover is now black to improve the appearance of the engine when used in a scale model.

The FSa-72 II has the same mounting dimensions of the previous generation as well as the older FL-70 and FS-70U. This makes it easy to change the engine. The compact external dimensions and power/torque are ideal for most models designed for 46cc 2-strokes or 70cc 4-strokes.
