OS Engines FSa-72 II with Silencer
The O.S. FSa-72 II is the latest version of this popular sized, high-performance four-stroke engine. Updates include a revised oil breather system which now vents from the crankcase rather than being re-ingested in the inlet to improve the running consistency. The rocker cover is now black in order to improve the appearance of the engine when fitted to a scale model. |
