O.S. Engine 110FS-a Four-Stroke  [OSMG0990]

You don't compromise, and also you don't wish your engine to, either. The 110FS-a doesn't compromise on performance, delivering 12.5per cent more power than the FS-91SII in identical room! But high-performance doesn't mean high-maintenance. Engine blow-by is trapped and re-used to constantly lubricate and bathe the machines working parts inside reducing friction and prolonging motor life.
