OS Engines FSa-110 w/F-5040 Silencer

IC Four Stroke Engine
Designed specifically to offer more power and torque compared to a .91 size four stroke, yet still fit in the same mounting dimensions, the FSa-110 is a real compact powerhouse.
Like all FSa series engines, the FSa-110 has near perfect carburetion across the RPM range, and thanks to the carefully designed exhaust, a soft yet authoritive note to minimise your presence to the neighbours.
Precision carburetion, internal oil recirculation and dramatic styling are all features of the FSa range and put this and the other derivatives that cut above the opposition.
